The article presents the thermal and physical properties of PMMA composite films with the addition of NbO nanoparticles. The addition of nanoparticles to PMMA mainly influenced the optical transmission and glass transition temperature of composite films compared to pure PMMA. It is clearly visible in the results of the conducted ellipsometric and differential scanning calorimetry tests. X-ray studies showed that the heat treatment of the samples resulted in the ordering of the polymer structure (flattening of the polymer chains). Examining the surface of the samples with scanning electron microscopy, it can be seen that NbO nanoparticles formed unusual, branched formations resembling "snowflakes".
本文介绍了添加了铌氧化物（NbO）纳米颗粒的聚甲基丙烯酸甲酯（PMMA）复合薄膜的热性能和物理性能。与纯PMMA相比，向PMMA中添加纳米颗粒主要影响了复合薄膜的光透射率和玻璃化转变温度。这在进行的椭偏测量和差示扫描量热法测试结果中清晰可见。X射线研究表明，样品的热处理导致聚合物结构有序化（聚合物链变平）。通过扫描电子显微镜检查样品表面，可以看到NbO纳米颗粒形成了类似“雪花”的异常分支结构。
