摘要
Grafted high density polyethylene (HDPE) films have been prepared by grafting sodium styrene sulfonate (SSS) and acrylic acid (AA) onto HDPE using preirradiation method.The structure and surface morphology of both grafted and ungrafted HDPE films were observed by FTIR spectroscopy and scanning electron microscope (SEM),respectively.The humidity sensing properties of grafted HDPE films were investigated.The results show that the impedance of the film decreases with increasing of relative humidity (RH).The films display high sensitivity with nearly three orders of magnitude change in the resistance during the relative humidity variation from 5% to 98%.Grafted HDPE films exhibit excellent properties as humidity sensors.
