Abstract :
Experimental results show the water molecule, as a plasticizer, or via ohmic conduction and its strong poling field, to be able to accelerate the charge decay of the poled LDPE specimen; also, as an accepter, to assist charge injection during poling of specimens. A newly found humidity-induced TSC peak at medium temperature could be attributed to dissociated ions from trap in amorphous-crystalline interface
