摘要：
We prepared polyethylene (PE) / multiwall carbon nanotube (MWNT) nanocomposites with various weight fractions using in situ metallocene polymerization. This polymerization method consists of attaching a metallocene catalyst complex on the surface of MWNT and being polymerized from that. All the procedures of polymerization made progress with one-pot process. The polymerized PE/MWNT nanocomposites showed uniform dispersion of MWNT in the PE matrix. The degree of dispersion has been characterized by means of scanning electron microscopy (SEM), and wide-angle X-ray diffraction (WAXD). Electrical conductivity and thermal conductivity were investigated.
