CHASM Advanced Materials and the practical rise of carbon nanotube hybrids

Why CHASM matters in advanced materials

CHASM Advanced Materials is best read as a carbon nanotube and nanotube-hybrid platform company, not simply a supplier of nanoscale powder. Its public product focus covers EV battery conductive additives, transparent conductive films, transparent antennas and heaters, EMI shielding, and cement or concrete additives. The central industrial question is whether carbon nanotubes can move beyond strong laboratory properties into materials that are cost-effective, scalable, dispersible and practical for manufacturers to qualify. Based on public company announcements through September 2026, CHASM is trying to answer that question through application-specific hybrid materials, regional production licensing and field demonstrations rather than one generic CNT product.

For readers following the materials sector, CHASM offers a useful case study in how nanomaterials are being packaged around real manufacturing bottlenecks: battery resistance, antenna placement, sensor icing, EMI shielding and the carbon footprint of concrete.

The product architecture behind CHASM advanced materials

Carbon nanotubes offer high electrical conductivity, low density, mechanical strength and flexibility. Those properties, however, do not create commercial value on their own. Manufacturers also need consistent morphology, purity, dispersion behavior, processing compatibility and predictable cost. CHASM’s public materials repeatedly describe a nanotube-hybrid approach, where CNTs are combined with another material system, such as graphite, carbon black, silver nanowires, copper mesh or cementitious ingredients, to create a more usable intermediate.

This architecture matters because each market qualifies materials differently. A battery maker will test electrode slurry behavior, resistance, cycle life, C-rate performance and supply security. An automotive engineer evaluating a transparent heater is more likely to focus on optical transmission, heat uniformity, voltage, durability and sensor beam distortion. A concrete producer has a different checklist again: batching, workability, compressive strength, long-term durability and code acceptance.

Battery materials make NTeC-E strategically important

The strongest near-term strategic case for CHASM is in battery materials. Lithium-ion batteries need conductive pathways inside electrodes so electrons can move efficiently between active particles and current collectors. Traditional conductive carbons remain widely used, but CNT additives can form conductive networks at relatively low loading when they are well dispersed and compatible with the electrode chemistry.

CHASM positions its NTeC-E platform as a high-purity CNT conductive additive for lithium-ion batteries, including commercial cathodes, high-nickel cathodes, silicon anodes, solid-state concepts and other emerging chemistries. Company technical literature lists typical NTeC-E values including CNT purity above 99.5 wt%, iron content below 10 ppm, median outer diameter around 10 nm, post-synthesis median length above 10 micrometers, and specific surface area above 300 m²/g. These figures help define the material target, but cell makers still need to validate performance in their own formulations and process windows.

The supply-chain angle is just as important. CHASM announced a partnership with Ingevity in March 2024 to expand CNT supply for North American and European EV battery markets. On November 11, 2025, the companies announced a license agreement granting Ingevity rights to manufacture CHASM’s NTeC-E conductive CNT additives for battery applications in North America and selected European countries. The announcement framed the license as a step toward regional CNT supply for gigafactories, building on earlier joint development work.

The commercial implication is straightforward: if regional battery supply chains want alternatives to CNT production concentrated in Asia, licensing and local manufacturing become part of the material value proposition. The limitation is equally important. Public announcements can report validation by partner labs, OEMs or third parties, but broad adoption still depends on multi-year customer qualification, plant ramp-up, cost stability, safety documentation and consistency at production scale.

AgeNT shows how CNTs move into transparent electronics

CHASM’s AgeNT platform addresses a different problem: how to make conductive films that are transparent, flexible and manufacturable. Public product descriptions say AgeNT films are made by printing carbon nanotubes onto silver nanowire or copper metal mesh substrates. In that hybrid structure, CNTs are used to reinforce more fragile conductive networks, add electrical redundancy and support surface connectivity.

The clearest commercial signal came in February 2024. CHASM announced a production expansion for customized transparent antennas, stating that production capacity exceeded 10 million transparent antennas annually. Later that month, at Mobile World Congress 2024 in Barcelona, the company said AgeNT transparent antenna solutions had entered full production and described carbon nanotube and copper hybrid antennas with greater than 90% optical transparency and performance comparable to low-loss ceramic PCB-based options.

Those announcements are relevant because transparent antennas solve a design constraint, not just a materials problem. mmWave, Wi-Fi, IoT, GNSS and future wireless systems often need more distributed antennas, while visible antenna structures can conflict with architecture, automotive design or device appearance. Transparent films allow antennas to be integrated into windows, light fixtures, camera covers or vehicle glass. In automotive sensing, the same film logic extends to transparent heaters for LiDAR covers, windshields, headlights and camera surfaces. CHASM’s April 16, 2024 participation in an fka GmbH and Driving Vision News consortium for adverse-weather LiDAR test methods also points to a market shift from material claims toward standardized performance evaluation.

Concrete applications target carbon and durability at once

Cement and concrete are harder to decarbonize than many materials because emissions come from both high-temperature heat and the chemistry of clinker production. The International Energy Agency and other climate references commonly place cement-related emissions at roughly 7–8% of global CO₂ emissions. That makes incremental reductions meaningful, provided the material can be produced, mixed and accepted at construction scale.

CHASM’s NTeC-C platform is positioned as a CNT-enhanced additive for cement and concrete. The company says the technology uses dry dispersion to integrate CNTs into cementitious systems, with the goal of improving mechanical performance while enabling greater use of supplementary cementitious materials such as fly ash, slag, calcined clay, volcanic ash or limestone. The core idea is that better crack resistance, strength development or durability could allow lower-clinker mixes to meet project requirements. See also: Application.

Two late-2025 demonstrations are notable, but they should be treated as field milestones rather than universal proof. On December 2, 2025, CHASM and the Cleveland County Economic Development Coalition announced a green concrete pour demonstration in Kansas, co-designed by Terracon and CHASM and conducted by Andale Construction at Air Capitol Materials in Wichita. The same announcement described a $24 million CHASM expansion in Cleveland County, Oklahoma, including a CNT and catalyst production facility intended to house two reactors, each with 1,500 metric tons of annual capacity, and projected 84 high-skilled jobs.

On December 30, 2025, CHASM and Saudi Readymix announced a CNT-enhanced green concrete demonstration at Saudi Readymix’s headquarters site in Dammam. The project used two adjacent 4 x 4 meter concrete pads, one with NTeC-C CNTs and one control mix, and the companies said the CNT-enhanced mix maintained workability under Saudi Readymix’s standard batching process. Continued monitoring remains important because concrete performance depends on environment, curing, mix design, loading and long-term durability.

A concise timeline of public milestones

What engineers and market watchers should evaluate next

CHASM’s public progress is significant because it touches three large markets at once: batteries, electronics and construction materials. The questions that matter most now are practical ones.

• Qualification depth: Battery and automotive customers will need repeatable data under their own process windows, not only supplier specifications.
• Reactor utilization: Announced capacity matters only when it becomes consistent product volume, yield and delivered cost.
• Dispersion and handling: CNT performance depends heavily on dispersion quality, binder compatibility, slurry viscosity and health-and-safety controls.
• Standards and codes: Concrete adoption will depend on mix approvals, durability records, carbon accounting and acceptance by engineers, owners and regulators.
• Application focus: CHASM’s hybrid strategy is strongest where CNTs solve a defined system problem, such as lower electrode resistance, transparent conductivity or stronger low-clinker concrete.

The broader lesson is that advanced materials adoption is rarely driven by a single property. It depends on the bridge between nanoscale performance and industrial qualification. CHASM’s most relevant contribution is its attempt to build that bridge through hybrid formats, licensing partnerships and application-specific manufacturing routes.
