Abstract
The investigation of conductive characteristics and surface structure of polyethylene films modified by fillers was carried out. The dependence of changes in surface and volume resistivity on the quantity of non-metallic filler and time-based changes in structure and electrophysical characteristics for three years has been established.
Highlights
The usage of polymer film materials for the needs of electronic equipment is mainly due to its minimization and the use as an auxiliary material
It was established that the surface resistivity of polyethylene films without filler had value near ρs ≈ 2⋅1010 Ω m
The surface resistivity of polyethylene films without filler has practically not changed during aging for 3 years in warehouse conditions
Summary
The usage of polymer film materials for the needs of electronic equipment is mainly due to its minimization (creation of transistors, radiating devices, etc.) and the use as an auxiliary material (barrier laying’s, flexible substrates and screens). Characteristics and properties of such materials should correspond to certain parameters of electronic products and provide the long lifecycle of devices. The main of the polymers materials used in the creation of various types of barrier and insulation materials is polyethylene. The polyethylene composition is modified in dependence of needs and terms of usage. The purpose of this research was to study the changes in the electrical conductivity of polyethylene films, modified by filled with inorganic non-conductive additives
