Abstract

This paper aims to present the statistical evaluation of dielectric constant (έ) and conductivity (σ) performance of composites preparing Maleic Anhydride (MA) and Styrene (St) polymer with various amounts of Cadmium Sülfide (CdS) by analysis of variance (ANOVA) model. For this purpose, frequency, applied voltage and CdS amount at different weight percentages were selected as input factors while dielectric constant and conductivity of the composites were selected as the response. Analysis of input factors was performed, RSM method was designed and used for estimation of response factor. From the analysis results, we found that high values of dielectric constant and conductivity were strongly related to frequency and CdS amount. However, we found that applied voltage in the selected ranges did not have a significant effect on both factors. The structural properties of the composites were investigated by Fourier Transform Infrared Spectroscopy (FTIR). The surface morphology was investigated by Scanning Electron Microscopy (SEM). The presence of CdS in polymers has been proven by X-Ray Diffraction (XRD). The thermal properties of polymers were examined by thermogravimetric analysis (TGA).

响应面法优化聚合物/CdS复合材料的电性能

本文采用方差分析（ANOVA）模型，对马来酸酐（MA）和苯乙烯（St）聚合物的介电常数（έ）和电导率（σ）性能进行了统计评价。为此，选择频率、外加电压和不同重量百分比的CdS量作为输入因素，选择复合材料的介电常数和电导率作为响应。对输入因子进行了分析，设计了响应因子估计的RSM方法。从分析结果中，我们发现介电常数和电导率的高值与频率和CdS量密切相关。然而，我们发现在所选范围内的施加电压对这两个因素都没有显着影响。利用傅里叶变换红外光谱（FTIR）研究了复合材料的结构性能。采用扫描电镜（SEM）对其表面形貌进行了研究。通过x射线衍射（XRD）证实了聚合物中存在CdS。用热重分析（TGA）检测了聚合物的热性能。图形摘要：trsm用于优化聚合物的电性能
