摘要
Abstract
A method for the controlled fabrication of polypropylene(PP)/polar polymer nanoalloys was presented. Its first step was the preparation of PP/ multi-walled carbon nanotubes(MWCNTs) nanocomposites by in situ polymerization with MWCNTs supported Ziegler-Natta catalyst. Then PP/poly(ε-caprolactone)(PCL) nanoalloys were prepared by the ring-opening polymerization ofε-caprolactone(ε-CL) initiated by hydroxyls on the surface of MWCNTs,in which the PCL molecular chains were grafted onto the MWCNTs surface. The catalyst,PP/MWCNTs nanocomposites and PCL were characterized by means of SEM,TEM,FTIR and GPC,and the morphology and stability of the PCL phase among the PP/PCL nanoalloys were investigated. The results indicated that the stable nano-size PCL phase formed among the PP/PCL nanoalloys and the phase size depended on the relative molecular mass of PCL. The PCL phase among PP exhibited uniform dispersity.关键词
