Preparation of Nano Carbon Black/Epoxy Composite by Frontal Polymerization

Abstract

Frontal polymerization is an fast, energy saving approach to prepare polymers and its composites. nanoCarbon /epoxy composite were prepared by frontal polymerization in this study. The composite was prepared using test-tube, and the reacting front was triggered by hot air gun. It was found that increasing the amount of hardener from 10wt% to 20wt%, the reacting frontal propagating velocity of pure epoxy system increased from 0.11mm/s to 0.34mm/s. With the increasing amount of nanocarbon black, the electrical conductivity of the composite was improved. Along the direction of the frontal polymerization, the conductivity of the composite did not change obviously which indicating the forming of uniform nanocarbon black/epoxy composite by frontal polymerization.
