乙烯-氯乙烯共聚物膜反常电导的某些特征
Some features of anomalous conductivity of vinylene and vinyl chloride copolymer films
摘要:
极性介电膜中的异常导电性的表现首次在乙烯和氯乙烯的共聚物样品上得到证明,正如以前在改性PVC样品上观察到的那样。在这些实验结果的基础上,对传统上在这些条件下使用的比电阻率指标的物理意义的重要新见解,体积和表面,应该分别用横向和纵向电阻(根据聚合物膜表面)代替,因为聚合物复合材料的比电阻率不允许像往常一样计算任意形式的样品的电阻。
英文摘要:
Manifestations of anomalous conductivity in polar dielectric films is demonstrated for the first time on samples of copolymer of vinylene and vinyl chloride, as was previously observed on modified PVC samples. On the base of these experimental results important new insights into the physical sense of traditionally used in these conditions specific resistivity indicators, both volume and surface, should be replaced by transverse and longitudinal resistance (according to polymer film surface) respectively, because the specific resistivity of polymer composite does not permits to calculate as usual the resistance of sample of arbitrary form..
