Research progress of new type carbon materials/polyolefin composite

In the last twenty years，owing to the excellent properties，the novel carbon material (including fullerene，carbon nanotube，graphene，etc.) has opened up a number of applications in many areas. This paper summarizes composites of carbon nanotube and graphene with polyolefin. The composites are made by physical blending and polymerization in situ，which improves mechanical properties，crystallization and melting，thermal stability，and conductivity. Furthermore，breakthroughs have been made in the following aspects：field emission display device，hydrogen storage materials，battery，ultra-intense and super tough composite，microscopic probe，super-capacitor，electron gun，nano-electronic components，and sensors.
