Abstract

A parallel-plate capacitor, which uses the commercial polymer poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) as dielectric material, was fabricated and characterized. The aim is to exploit the ability of the nanoporous-crystalline (NC) phases of this polymer (α and β) to absorb volatile organic compounds (VOC), even when present at trace levels. Capacitance changes of the prepared capacitors due to the sorption of two analytes (carbon tetrachloride and methyl ethyl ketone), whose dielectric constants are lower and higher (2.2 and 18.5, respectively) with respect to PPO (2.5), are reported. This study provides a preliminary demonstration that capacitors based on the NC forms of PPO, are promising as chemicapacitors for many VOCs.

基于PPO的化学电容器的蒸气响应

制备了一种以商用聚合物聚（2,6-二甲基-1,4-苯基）氧化物（PPO）为介质材料的并联板电容器，并对其进行了表征。目的是利用这种聚合物（α和β）的纳米多孔晶体（NC）相吸收挥发性有机化合物（VOC）的能力，即使存在微量水平。报道了相对于PPO（2.5）的介电常数较低和较高（分别为2.2和18.5）的两种分析物（四氯化碳和甲基乙基酮）吸附所制备电容器的电容变化。本研究初步证明了基于PPO的NC型电容器作为多种VOCs的化学电容器是有前景的。
