Abstract
The present invention relates to a polyurethane foam comprising graphene, wherein the polyurethane foam comprises graphene structure and a non-carbon non-oxygen non-hydrogen element. By choosing a specific composite having a carbon nanostructure, the present invention achieves compounding polyurethane via simply mixing with polyether polyol, and then polymerizing with polyisocyanate, omitting the step of compounding the composite having a carbon nanostructure, having a simple process and seamlessly connecting with existing equipment.
