Abstract

Results are presented from measuring optical density in the ultraviolet (UV) and visible ranges of polymer films made of polysulfone (PSF), polymethyl methacrylate (PMMA) and polyvinyl alcohol (PVA) with embedded CNTs, produced by mixing solutions. It is found that adding CNT increases the optical density of polymers, and the efficiency of absorption depends on the choice of polymer. Coefficients of extinction are calculated for CNT in PSF, PMMA, and PVA. The results can be used to develop a way of monitoring the homogeneity of CNT distribution in polymer films.

Taunit 碳纳米管对聚砜、聚甲基丙烯酸甲酯和聚乙烯醇聚合物薄膜光密度的影响

本研究介绍了通过混合溶液生产的嵌入 CNT 的聚砜（PSF）、聚甲基丙烯酸甲酯（PMMA）和聚乙烯醇（PVA）聚合物薄膜在紫外线（UV）和可见光范围内的光密度测量结果。研究发现，添加 CNT 会增加聚合物的光密度，而吸收效率则取决于聚合物的选择。计算了 CNT 在 PSF、PMMA 和 PVA 中的消光系数。这些结果可用于开发一种监测 CNT 在聚合物薄膜中分布均匀性的方法。
