Abstract

In this study, pure polymer blend (PVA:PVP) film and salt (CdCl2·H2O) reinforced polymer blend films were prepared at different weight ratios (10 wt%, 20 wt%, 40 wt%) using the casting method. The effect of the salt weight ratio on the dielectric properties of the polymer blend films reinforced by CdCl2·H2O salt were investigated, and the experimental results showed that the dielectric constant and the dielectric loss factor decreased as the frequency increased for all polymer blend films. Moreover, the above-mentioned properties increased with increasing salt weight ratios at the same frequency. The experimental results also showed an increase in AC electrical conductivity with increasing frequency, for all polymer blend films, and the AC electrical conductivity also increased with an increase in the weight ratio of the salt at the same frequency. The effect of the salt weight ratio on the mechanical properties of the salt-reinforced PVA:PVP polymer blend films was also studied. The experimental results obtained from the tensile test of the salt-reinforced polymer blend films show significant change in the values of tensile strength, elongation at break, and Young’s modulus with increasing salt weight ratios; the hardness value first increases then decreases with increasing salt weight ratios, and the fracture energy value increases with increasing salt weight ratios, thus they could be good candidates for hard adhesives with low flexibility.

氯化镉增强PVA:PVP共混膜的电学和力学性能

本研究采用流延法制备了不同重量比（10wt%、20wt%、40wt%）的纯聚合物共混物（PVA:PVP）薄膜和盐（CdCl2·H2O）增强聚合物共混物薄膜。研究了盐重比对CdCl2·H2O盐增强聚合物共混膜介电性能的影响，实验结果表明，所有聚合物共混膜的介电常数和介电损耗因子都随着频率的增加而降低。此外，在相同频率下，上述性质随着盐重量比的增加而增加。实验结果还显示，对于所有聚合物共混膜，AC电导率随着频率的增加而增加，并且在相同频率下，AC电导率也随着盐的重量比的增加而增大。研究了盐重比对盐增强PVA:PVP共混膜力学性能的影响。从盐增强聚合物共混膜的拉伸试验获得的实验结果显示，拉伸强度、断裂伸长率和杨氏模量的值随着盐重量比的增加而显著变化；硬度值随盐重比的增加先增大后减小，断裂能值随盐重量比的增加而增大，是低柔性硬质胶粘剂的理想选择。

期刊介绍： Papers in Physics publishes original research in all areas of physics and its interface with other subjects. The scope includes, but is not limited to, physics of particles and fields, condensed matter, relativity and gravitation, nuclear physics, physics of fluids, biophysics, econophysics, chemical physics, statistical mechanics, soft condensed matter, materials science, mathematical physics and general physics. Contributions in the areas of foundations of physics, history of physics and physics education are not considered for publication. Articles published in Papers in Physics contain substantial new results and ideas that advance the state of physics in a non-trivial way. Articles are strictly reviewed by specialists prior to publication. Papers in Physics highlights outstanding articles published in the journal through the Editors'' choice section. Papers in Physics offers two distinct editorial treatments to articles from which authors can choose. In Traditional Review, manuscripts are submitted to anonymous reviewers seeking constructive criticism and editors make a decision on whether publication is appropriate. In Open Review, manuscripts are sent to reviewers. If the paper is considered original and technically sound, the article, the reviewer''s comments and the author''s reply are published alongside the names of all involved. This way, Papers in Physics promotes the open discussion of controversies among specialists that are of help to the reader and to the transparency of the editorial process. Moreover, our reviewers receive their due recognition by publishing a recorded citable report. Papers in Physics publishes Commentaries from the reviewer(s) if major disagreements remain after exchange with the authors or if a different insight proposed is considered valuable for the readers.
