Air-gap thermally stimulated discharge currents in PVDF-PMMA double-layered samples

In this paper, we have reported the interpretation of air gap TSDC of surface charges in polyvinylidene fluoride (PVDF)-poly (methyl methacrylate) PMMA double-layered polymer thin films. The influence of the layered structure semicrystalline poly (vinylidene fluoride) (PVDF) and amorphous poly (methyl methacrylate) (PMMA) on their electret properties was investigated in detail using the air gap thermally stimulated discharge current technique....
