Polymers filled with highly expanded graphite

摘要

Polymers are filled with from 1 to 8% by weight of an expanded graphite having a BET surface area of at least 120 m²/g. Processes for preparing such polymers include forming a dispersion of the expanded graphite in a polymerizable monomer or curable polymer precursor, and polymerizing or curing same in the presence of the expanded graphite. Electroconductive polymers can be prepared in this manner using low levels of the expanded graphite material.
