摘要

In this work, the properties of LDPE were modified by SiO_2-EVA (Ethylene Vinyl Acetate copolymer) composite, while EVA contributed to prevent nanometer SiO_2 particles from conglomerating. The results show that the polarity of nano-modified PE films increase from 30 dyne/cm to 35 dyne/cm, the friction coefficient drop 1/2 by itself, and the surface resistance decrease 2～3 magnitudes compared with the un-modified. Also, the crystallization of the films and the crystal particles increase effectively due to addition of nano-SiO_2. Hence, the thermal stabilization and elastic modulus of the films can be enhanced, so as to improve the comprehensive properties and reduce existed problems of PE films in applications of printing and packaging industry.
