Method for Producing Graphene Nanolayers

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for producing graphene nanolayers by mixing graphite with a polymerizable substance—such as natural or animal oils—forming an intercalated graphite compound, then exfoliating the graphite via in situ polymerization, and finally isolating the graphene nanolayers. The process offers a simpler and more cost-effective way to make high-quality graphene nanolayers with controlled thickness and excellent electronic, thermal, and mechanical properties.
