Abstract

The nucleophilic substitution reaction of activated aryl dihalide was used to synthesize heat-resistant thermoplastic polymers, that is, cardo co-poly(arylene ether ketone)s (co-PAEK) with different contents of fluorene fragments. Thermomechanical and electronic properties of thin films of the copolymers were studied, taking into account the prospects of their application for the formation of an electrical contact conducting oxide—polymer-metal. Influence of charge carrier concentration and effective mobility in the polymer were revealed depending on the composition of the cardo co-PAEK in the indium—tin oxide (ITO)—co-PAEK—copper structure. The potential barrier height at the co-PAEK—copper and co-PAEK—ITO interfaces was determined, the effect of changes of the electron work function of ITO on these values was studied. Changes in the parameters of charge carriers and changes in potential barriers over time were investigated.

半导体-聚合物-金属结构中碳共聚（芳醚酮）组成对载流子输运的影响

利用活化芳基二卤化物的亲核取代反应，合成了不同芴片段含量的cardo共聚芳醚酮（co-PAEK）耐热热塑性聚合物。研究了共聚物薄膜的热力学和电子性能，并展望了其在形成电接触导电氧化物-聚合物-金属中的应用前景。揭示了在氧化铟锡(ITO) - co-PAEK -铜结构中，载流子浓度和有效迁移率对co-PAEK的影响。测定了co-PAEK-copper和co-PAEK-ITO界面的势垒高度，研究了ITO的电子功函数变化对势垒高度的影响。研究了载流子参数和势垒随时间的变化。
