摘要

聚合物薄膜电容器在高温环境下的充放电效率和能量密度会急剧下降，这仍然是一个亟待解决的问题。本文利用常压等离子体射流（APPJ）沉积 TiO2，以改善双向拉伸聚丙烯（BOPP）薄膜在高温环境下的储能性能。APPJ 以氩气为工作气体，采用多电极接地配置以获得稳定的喷射状态。前驱体溶液采用钛酸四乙酯（TET）与乙醇以 5:3 的比例混合配制而成。结果表明，在 120°C 下，APPJ 沉积的 BOPP 薄膜的充放电效率和放电能量密度（从 3.1 到 5.7 J cm-3）都得到了提高。

Improving high‐temperature capacitive energy storage of biaxially oriented polypropylene through titanium dioxide deposition layer by atmospheric pressure plasma jets

Polymer film capacitors experience a sharp decrease in charge–discharge efficiency and energy density under high‐temperature environments, which remains an urgent issue to address. In this article, atmospheric pressure plasma jet (APPJ) is used to deposit TiO2 to improve the energy storage performance of biaxially oriented polypropylene (BOPP) film in high‐temperature environment. The APPJ uses argon as the working gas and adopts a multielectrode grounding configuration to obtain the stable jet state. The precursor solution is prepared using tetraethyl titanate (TET) mixed with ethanol in a ratio of 5:3. The results show that the charge–discharge efficiency and discharge energy density (from 3.1 to 5.7 J cm–3) of BOPP films deposited by APPJ are improved at 120°C.
