The loss of polymer materials is closely related to dielectric properties such as breakdown and the internal charge transport behavior of polymers, and adding chemical additives containing specific functional groups to introduce chemical trap energy levels into polymers is an effective way to improve the dielectric properties of polymers. Since the 60s of the twentieth century, chemical additives have been used to inhibit the long-term electrical aging of polymer insulating materials and improve the electrical resistance of insulating materials. The modifier that can capture high-energy electrons is called thermos-electron trap, which has the ability to regulate charge transport and improve the dielectric properties of insulating materials, and is one of the most widely studied organic modifiers.
