- W605438315 abstract "In this paper composites were prepared by coupling to the nano SiO2 precipitation into the linear low density polyethylene (LLDPE) / low density polyethylene (LDPE) hybrid system, then the blown film extrusion blow molding system film, a film on the mechanical properties, optical properties. The results showed that SiO2 nanopowder could induce crystallization of polyethylene (PE), the sphemlites of the crystal decreased with the increase of SiO2, content; with the increase in nano SiO2, composite materials, the tensile strength and elongation at fracture, the first increase after the decrease in the powder content of 3% maximum. The IR absorptivity (ranging from 7 um to 11 um) of the composite films increased dramatically with the nano SiO2 introduced. Although the visible light transmittance of the film declined a little compared with the pure LLDPE. the haze value increased much. It was also found that the surface treatment method of nano SiO2 had great influence on the optical properties of the composite films. The infrared absorptive and haze of the composites filled with nano SiO2 treated by silan ecoupling agent in ethanol were superior to those of the composites tilled with nano SiO2 treated by silane coupling agent in a ball mill, because the former had smaller particle size and more uniform dispersion in matrix than the latter." @default.
