Polyolefin's molecular structure primarily consists of low-reactivity sp3 hybridized carbon atoms and exhibits a certain degree of crystallinity.These characteristics limit its toughness,adhesion,compatibility,rheology,printing and dyeing capabilities as well as hinder the functionalization potential of polyolefin materials.The functionalization of polymers represents a highly effective approach for the synthesis of novel materials and enhancement of polymer properties,thus finding extensive applications in various fields.In this paper,a comprehensive review is presented on the post-functionalization methods of polyolefins,with particular emphasis on radical grafting and C-H activation.Furthermore,an outlook is provided for future research directions in the field of polyolefin post-functionalization.
