“…In situ polymerization is the most often method for preparation graphene/PA6 and other graphene-filled polymer composites including epoxy [84][85][86][87][88] , PS 89 , PMMA 90,91 , PU 92,93 , PE 94 , PANI [95][96][97] , PI 98-101 , etc. This method consist two main steps: 7,8,55,57 1. Graphene or its derivative is mixed pure monomers (or multiple monomers, a solution of monomers).…”
