Effect of SrO nanofillers on the physical and chemical properties of newly prepared PVA nanocomposites was investigated in‐depth in this article. The structure of SrO nanopowder and PVA nanocomposites were analyzed using FTIR for surface chemistry and XRD for crystallographic nature. The extent of dispersion and particle size of SrO nanopowders were obtained from TEM micrographs. The average particle size of the SrO nanopowder was 57 nm. The uniformly dispersed SrO nanofillers in the host PVA matrix were observed from the TEM micrographs. The prepared PVA nanocomposites displayed a high absorption in the UV region. The thermal stability of PVA nanocomposites was enhanced after the addition of SrO nanofillers. The nonisothermal degradation study was carried out using different kinetic models for the prepared PVA nanocomposites. The Young's modulus (Y) and tensile strength of the PVA nanocomposites were higher than that of the pristine PVA. The DC conductivity of PVA was also increased when the PVA was embedded with the SrO nanoparticles.

嵌入SrO纳米填料的新型PVA纳米复合材料的热，机械和电性能的增强及其非等温方法的热降解行为分析

本文深入研究了SrO纳米填料对新制备的PVA纳米复合材料的物理和化学性质的影响。SrO纳米粉和PVA纳米复合材料的结构使用FTIR进行表面化学分析，使用XRD进行晶体学分析。SrO纳米粉的分散程度和粒径可从TEM显微照片中获得。SrO纳米粉的平均粒径为57nm。从TEM显微照片观察到在主体PVA基质中均匀分散的SrO纳米填料。制备的PVA纳米复合材料在UV区显示出高吸收。加入SrO纳米填料后，PVA纳米复合材料的热稳定性得到增强。使用不同的动力学模型对制备的PVA纳米复合材料进行了非等温降解研究。年轻人' PVA纳米复合材料的s模量（Y）和拉伸强度高于原始PVA。当PVA嵌入SrO纳米颗粒时，PVA的DC电导率也增加。
