Transport processes in polymeric solids - the role of the surface and the electrodes

摘要

A non-contacting high definition induction probe surface-potential monitor, together with pulsed corona charging, produces a versatile tool for the study of both dielectric and conduction processes in highly insulating solids and is capable of yielding data of good accuracy under conditions not easily attainable, if at all, by conventional techniques. Moreover, the influence of metal electrodes can be determined with great clarity. Theoretical treatment of the results permits a new insight into the detailed mechanisms of both polarization and conduction processes.
