Electron beam (EB) irradiation was known to be a facile and effective method for the crosslinking of polymeric materials, owing to its advantages including absence of noxious additives, high crosslinking density, uniform irradiation, thickness throughout, etc. In this study, we have manufactured a series of crosslinked nanocomposite films based on high density polyethylene (HDPE) and multiwalled carbon nanotube (MWCNT) by hot-compression and EB irradiation. The structures, thermal and electrical properties of the nanocomposite films were investigated as a functions of MWCNT content (1.0-10.0 wt%) and EB irradiation dose (0-600 kGy) by using electron microscopes, differential scanning calorimeter, and multimeters, respectively. The positive temperature coefficient of electrical resistance of the HDPE/MWCNT nanocomposite films was also characterized for the potential application as electric heating elements. |
