Copper nanoparticles composition-based polyvinyl alcohol/polyvinylpyrrolidone (PVA/PVP) composite films were prepared for select concentrations. AC conductivity, dielectric permittivity, UV–visible and FTIR studies along with X-ray diffraction analysis were carried out on these composites. From this conductivity study, DC conductivity was estimated along with hopping potential, hopping length and thermal conductivity using power law of the frequency-dependent AC conductivity. A correlation study of these parameters using functional analysis method to establish structure–property relation in these composites was also carried out.

铜纳米颗粒基PVA / PVP复合材料的结构-性能关系

制备用于选择浓度的基于铜纳米颗粒组合物的聚乙烯醇/聚乙烯吡咯烷酮（ PVA / PVP）复合膜。在这些复合材料上进行了交流电导率，介电常数，UV可见光和FTIR研究以及X射线衍射分析。从该电导率研究中，使用频率相关的交流电导率的幂定律估算直流电导率以及跳变电势，跳变长度和热导率。还使用功能分析方法对这些参数进行了相关性研究，以建立这些复合材料的结构-性能关系。
