Abstract

Six ratios of nanosilica particles were employed to fabricate low-density polyethylene (LDPE) composites using melt mixing and hot molding methods. Several composite films with different ratios (0.5, 1, 2.5, 5, 7.5, and 10 wt%) of SiO2 were prepared. The obtained composite films were identified and characterized by Fourier-transform infrared spectroscopy (FTIR) and ultraviolet-visible spectroscopy (UV-VIS). At a specific mixing ratio, far infrared radiation transmittance was prohibited while the ultraviolet-visible transmittance is allowed; this will be explained in detail. Optical measurements show that the composite films prevent the transmission of IR radiation near 9 μm and allow UV-VIS transmission during sun-shining time. The mechanical behaviour of a nanosilica-reinforced LDPE composite was studied using tensile tests. The addition of 1 wt% nanosilica has successfully enhanced the mechanical properties of the LDPE material.
