A dielectric study of interfacial water in silane-modified HDPE-glass composites

摘要: Model composites of spherical glass particles dispersed in a matrix high density polyethylene (HDPE) were studied both with and without interfacial modification by an azidofunctional trialkoxysilane. The layer coverage was controlled varying the amount silane used for modifying sphere surfaces. dielectric properties silane-modified as function water content samples after equilibrium uptake. absorbed via relative humidity environment to which exposed. Measurements performed temperature between 0°C 30°C frequency from 100 mHz 1 MHz. A polarization process due adsorbed at filler surface detected. theoretical interlayer model particulate-filled is present shown predict detected loss...
