Poly ethyl methacrylate (PEMA) films doped with various concentrations of a mixed filler (CoCl2 and LiBr) were prepared by using the casting method and their morphological, thermal and electrical properties were investigated. Scanning electron microscopy showed partial compatibility between the PEMA and the mixed filler. Differential scanning calorimetry was shown to increase their thermal stability with an increase in the concentration of the mixed filler in the films. The electrical properties were investigated using DC electrical conductivity (σ), which showed an improvement in electrical conductivity after addition of the mixed filler.

在 PEMA 中加入 CoCl2 和 LiBr 混合填料的影响及其形态、热和电性能

采用浇铸法制备了掺杂不同浓度混合填料（CoCl2和LiBr）的聚甲基丙烯酸乙酯（PEMA）薄膜，并研究了它们的形态、热学和电学性能。扫描电子显微镜显示 PEMA 和混合填料之间有部分相容性。差示扫描量热法显示出随着薄膜中混合填料浓度的增加而增加它们的热稳定性。使用直流电导率 (σ) 研究电性能，表明添加混合填料后电导率有所提高。
