Structural, optical, thermal, morphological and electrical features of pure blend and composites based on poly(ethyl methacralyte) (PEMA) and poly (methyl methacrylate) (PMMA) filled with different contents of cobalt chloride (CoCl₂) and lithium bromide (LiBr) were investigated. The composite samples at various concentrations of mixed filler were prepared using the casting method. X-ray diffraction (XRD) showed an amorphous feature of the pure blend films. Fourier transform infrared (FT-IR) spectra depicted that components of the blend, PEMA and PMMA polymers, are miscible. Ultraviolet and visible (UV–Vis.) measurement revealed that the values of the optical energy gap are decreasing with increasing mixed filler concentrations. Scanning electron microscopy (SEM) after adding the mixed filler shows small granules and bright spots on the surface of the blend. Differential scanning calorimetry (DSC) results show that adding mixed filler to polymeric solution enhances their thermal stability. The plot of DC conductivity versus temperature shows the Arrhenius model (linear variation).

基于填充有不同含量氯化钴（CoCl ₂）的聚（甲基丙烯酸甲酯）（PEMA）和聚（甲基丙烯酸甲酯）（PMMA）的纯共混物和复合材料的结构，光学，热，形态和电学特征）和溴化锂（LiBr）。使用浇铸方法制备了各种浓度的混合填料的复合样品。X射线衍射（XRD）显示出纯共混膜的非晶态特征。傅立叶变换红外（FT-IR）光谱表明，共混物的成分PEMA和PMMA聚合物是可混溶的。紫外线和可见光（UV-Vis。）测量显示，随着混合填料浓度的增加，光能隙的值正在减小。添加混合填料后的扫描电子显微镜（SEM）显示小颗粒和共混物表面上的亮点。差示扫描量热法（DSC）结果表明，向聚合物溶液中添加混合填料可增强其热稳定性。
