Abstract

The surface potential decay measurement of the blend polyethylene nanocomposites film containing the untreated and treated (trimethoxy (propyl)silane) nanosilica is conducted in this research for further studying how nanoparticles and moisture absorption affect the charge transport and electrical properties. The surface potential decay measurements were investigated over the negative corona charged voltage in a controlled environment where the temperature and relative humidity were kept at 23 ℃ and 30 % respectively. All specimen were grouped and conditioned as a function of relative humidity. Comparing with the reference sample (non-filled and dry), the surface potential decay rate decreases initially and then increases with the nanosilica loading ratio while it increases monotonically with the absorbed water .
