The Preparation of CNTs/PE Nanocomposites Particles with Coral Shape and Core-Shell Structure In Situ Produced via Nanotemplate Catalyst Based on MWCNTs

A kind of nano template catalyst was prepared through loading the active compound (m-CH3PhO)TiCl3 on carbon nanotubes (CNTs). This catalyst can catalyze (co)polymerization of ethylene to form CNTs/polyethylene (PE) nanocomposites particles. The nano template catalyst showed high catalytic activity up to 5.8 kg/(gTi.h.p) for the copolymerization of ethylene with 1-hexene. The results revealed that the nascent CNTs/PE nanocomposites particles looked like coral shape and featured with the core-shell structure which CNTs as the core and polyethylene as the shell.
