• Scalable Process for Post-coating CNS Flake

– Density Easily Tailored to Achieve Flow of CNS for

Compounding

• Low Polymer Weight Post-Coat Targeted to Maintain CNS Network

• 0.13 gm/ml Achieved with ~10% Polymer Post-Coat

3 Highly-Entangled, Cross-Linked CNS Network

• Leveraging CNS to Improve Base Material Properties

– Mechanical Properties

– EMI Shielding

– Electrical Conductivity

– Thermal Conductivity

– Radiation Absorption

• CNS Network Yields Safety Discriminator vs. CNT

– Less Likely to Release Individual CNTs

– Reduced Risk of Respirable, Durable Fiber
