Standard graphene dispersions need surfactants to stay stable — which contaminate every surface they touch. Standard GO dispersions skip the surfactants but sacrifice conductivity through oxidation damage. Either way, you end up with disappointing data. Flexiphene™ was built to solve both problems at once. 100× lower resistance. +19% polymer strength. NASA validated. Free sample.

Graphene is theoretically one of the most remarkable materials on the planet. But standard commercial dispersions force a fundamental trade-off: use graphene (G) and fight agglomeration and surfactant contamination, or use graphene oxide (GO) and sacrifice the conductivity you're trying to exploit. Flexiphene™ is the first to resolve both without compromise.
Pristine graphene is hydrophobic and thermodynamically unstable in water — sheets restack and agglomerate. Without intervention, you get clumps, not dispersion. Standard G dispersions rely on surfactants or intensive sonication to force stability, both of which create their own problems.
Surfactants prevent restacking in graphene dispersions, but they coat every carbon surface in the process — blocking electrical contact, contaminating polymer matrices, and interfering with electrochemical performance. You pay for graphene but your results reflect surfactant-coated graphene.
GO solves the agglomeration problem — it's highly water-soluble without surfactants. But Hummers-method oxidation introduces sp³ defects throughout the graphene lattice, destroying the conjugated π-system. GO's electrical resistance is orders of magnitude higher than pristine graphene. Reduction partially restores conductivity, but structural damage cannot be fully reversed.
Whether you're using G or GO, most commercial graphene dispersions show significant batch-to-batch variability — in concentration, particle size distribution, oxidation degree, and surface chemistry. Reproducing results between experiments, let alone qualifying a process for production, becomes a research project in itself.
GO can be reduced to restore some conductivity — but the sp² lattice damage from oxidation is irreversible. Even with optimal reduction, rGO reaches roughly 10–40% of pristine graphene conductivity. If your application demands high conductivity, you've hit a hard ceiling that no reduction protocol can break through.
Both routes lead to the same outcome: graphene or GO additions that deliver marginal, inconsistent improvements. High loadings to compensate. Data that can't be reproduced in the next experiment. Results that don't match theoretical predictions — because the material in the vial isn't what's on the spec sheet.
These are not marketing claims — they are measured results from ASTM-standard mechanical testing and a peer-reviewed NASA JPL publication.

Electrical data: Noell et al., Electroanalysis (2020), NASA JPL. Polymer data: ASTM Type V tensile / ASTM D790 flexural, PA 66 at 1 wt.% Flexiphene™ loading. Surfactant and agglomeration rows compare against standard graphene (G) dispersions. GO dispersions are water-soluble without surfactants but sacrifice conductivity through oxidation damage — see section below.
Flexiphene™ maintains dispersion stability through patented surface engineering of the nanocarbon structure itself — not by adding surfactants or aggressively oxidizing the carbon. The result is a proprietary nanocarbon dispersion that stays stable, performs consistently, and doesn't compromise your application with contamination.
