摘要

A good method for dispersing Multi-walled carbon nanotubes (MWNTs) in LDPE matrix by melt processing technique had been developed. The surface of MWNTs was modified by HNO3, then, treated with γ-aminopropyltriethoxy Silane. The surface-modified MWNTs homogeneous LDPE composites with 0-0.35 mass fraction MWNTs loading had been evaluated for electrical conductivity. The composites' electrical conductivity (σDC) was improved for the good dispersion of MWNTs in LDPE matrix. The values of aoc obeyed a percolation power law with MWNTs concentration threshold 0.10 mass fraction. 10-2 s/cm conductivity for 0.15 mass fraction MWNTs loading indicated that the composites could be used as lightweight electrostatic shielding materials.
