Most CNT dispersions require surfactants — which coat every tube surface and destroy the very properties you're trying to exploit. Flexiphene™ dispersion achieves stable, uniform dispersion without surfactants, delivering measured results: 100× lower resistance, +19% polymer strength, and 90% batch consistency. Validated at NASA JPL.

Carbon nanotubes have extraordinary intrinsic properties — but achieving those properties in a usable dispersion is genuinely hard. The van der Waals attraction between tubes is strong enough that they spontaneously bundle, and unbundling them without damaging the tube structure or contaminating the dispersion is the central challenge of CNT materials science.
Result: Expensive CNTs delivering marginal, irreproducible improvements
Result: Measured, reproducible performance improvements. Every batch.

Flexiphene™ is not just a CNT dispersion — it's a patented multi-component nanocarbon architecture where different nanocarbon allotropes work synergistically. This is the key insight that makes the performance numbers possible.
The planar nanocarbon component provides large surface area with abundant functional groups. It stabilizes the nanotube network spatially, prevents rebundling, and provides direct bonding points to polymer matrices and electrode surfaces.
High-aspect-ratio nanotubes bridge across the nanocarbon scaffold, creating continuous 1D electron pathways through the network. The combination of planar surface area and nanotube conductivity is what produces the 100× resistance improvement and 96× capacitance gain.
Flexiphene™'s patented architecture forms a 3D interconnected nanocarbon network — the planar component provides area coverage, the nanotubes bridge gaps. This network is more robust and more conductive than single-component dispersions at equivalent loading.
The patented dispersion process maintains this 3D network structure in liquid suspension — surfactant-free — through proprietary surface chemistry that prevents bundling without contaminating the carbon surfaces.
Flexiphene™ can be thermally or chemically reduced post-application to further enhance conductivity. This two-stage approach combines excellent processability with maximum electrical performance — on demand.
Up to 10× higher interfacial activity compared to standard oxidized CNTs — more contact area, more functional groups for bonding, more reinforcement per gram delivered by Flexiphene™'s multi-allotrope architecture.
