説明

The residual voltage which appears in a pre-stressed polyethylene film is found to increase with increasing draw ratio and then to decrease again at higher draw ratio. On the other hand, the ratio of a surface potential decay decreases with increasing draw ratio and then again increases at higher ratio. These results are discussed in terms of the change of the carrier transport process, localized state density and carrier mobility.
