Reasearch Progress in High Value Modification of Polyolefins and Their Application

The high-value modification methods of polyolefin materials and the applications of modified polyolefin materials in the fields of conductivity,dielectric,light transmission and luminescence were reviewed. The introduction of carbon materials into polyolefins by physical or chemical methods was the main method to prepare conductive polyolefins,which can effectively reduce the resistivity of polyolefins. Copolymerization and blending methods can also change the dielectric properties of polyolefins or afford polyolefins with ionic conductivity,which can be applied in capacitors or lithium batteries. Polyolefin copolymers with high transmittance can be prepared by copolymerizing polyolefin materials. If the conjugate structure was introduced into the main or side chains of polyolefins,it can also give them excellent luminescent properties,which can be applied in the fields of optoelectronics.
