Abstract

The temperature dependence of the conductivity of heat-treated polyvinyl chloride films containing conjugated double carbon–carbon bonds in the chain of its macromolecules and representing polyvinyl chloride–polyacetylene copolymers is studied. The samples with an above threshold concentration of conjugated carbon–carbon double bonds and associated charge carriers (π-electrons) exhibit changes in the conductivity by ten orders of magnitude as the temperature increases. It is found that the semiconducting state of the copolymer in the temperature range, the width of which depends on the concentration of conjugated double carbon–carbon bonds and associated charge carriers, is unstable. Qualitatively, the increase in the concentration of conjugated double carbon–carbon bonds was controlled by recording photoluminescent spectra and infrared absorption spectra.

聚氯乙烯-聚乙炔共聚物的电学和光学性质

摘要

研究了热处理的聚氯乙烯薄膜的电导率对温度的依赖性，该薄膜在其大分子链中包含共轭双碳-碳键，代表聚氯乙烯-聚乙炔共聚物。随着温度升高，具有高于共轭碳-碳双键和相关电荷载流子（π电子）的阈值浓度的样品的电导率变化十个数量级。发现在该温度范围内共聚物的半导体状态是不稳定的，该温度范围的宽度取决于共轭双碳-碳键和相关电荷载体的浓度。定性地，
