Abstract

ABSTRACT: In this paper, the distribution of trap levels of alumina/polyethylene (Al2 O3 /LDPE) modified by maleic anhydride (MAH) was studied by photo-stimulated discharge (PSD). The PSD results show that the energy level of charge traps in the 0.5% and 1% Al2 O3 /LDPE modified by MAH is mainly distributed in 4.68–5.64 eV, and the trap density maximum is at 235 nm and 230 nm, respectively. According to the experimental result, the maleic anhydride can provide pure polyethylene with abundant deep traps. However, it can effectively reduce trap density of the Al2 O3 /LDPE system, especially, this kind of mechanism of action is more obvious for the 1%-doped Al2 O3 /LDPE system.
