Specific features of the electret effect in two-layer polymeric films

Effect of aluminum oxide coating on structural, barrier and electret properties of polyethylene terephthalate films

“…For this reason different methods are used to increase quantity of charge carrier traps with high capture energy. It includes polymer filling [9][10][11][12][13], foaming [14][15][16][17] and surface modification [18][19][20][21][22]. Another promising technique is synthesis of low molecular weight nano-sized clusters on the polymer film that are able to capture homocharge responsible for electret state [18][19][20].…”

Organic molecular and polymeric electrets toward soft electronics

“…17 While among organic electrets, the dominant dielectric materials are polymers, such as polytetrafluoroethylene (PTFE), 18 polyethylene (PE), [19][20][21] polypropylene (PP), 22 polyethylene terephthalate (PET), 23 polyimide (PI), 24 polyIJmethyl methacrylate) (PMMA), 25 polyvinylidene fluoride (PVDF), 26 and ethylene vinyl acetate (EVA). 27 Typical representatives of organic electret are shown in Table 1. They all show high insulating properties.…”
