Abstract We report that alcotex/3-aminopropanoic acid (PVA-β-alanine) polymer thin film was synthesized by taking different concentrations of PVA-β-alanine by the solution casting process, and their structural, opto-electrical and ionic conductivity were examined for the first time. In the X-ray diffraction (XRD) study, the crystallite structure of the semi-crystalline film can be clearly seen with an increase in β-alanine and a decrease in the PVA concentrations. The presence of functional groups and optical response was analyzed for the prepared material using the Fourier Transform Infrared (FT-IR) and optical absorption tests. The wider optical band gap values are calculated to be 4.89 to 5.07 eV using the Tauc plots for polymer thin film materials at various PVA-β-alanine concentrations. The effects of various PVA/β-alanine wt% concentrations on the ionic conductivity, electrochemical impedance spectroscopy (EIS) parameters, power-law exponent (n) and hopping frequency of the prepared polymer films have been elucidated.

alcotex/3-氨基丙酸聚合物薄膜的合成及其结构和光电特性

摘要 我们报道了通过溶液浇铸工艺采用不同浓度的 PVA-β-丙氨酸合成了 alcotex/3-氨基丙酸 (PVA-β-丙氨酸) 聚合物薄膜，并对其结构、光电和离子电导率进行了研究。首次。在 X 射线衍射 (XRD) 研究中，随着 β-丙氨酸的增加和 PVA 浓度的降低，可以清楚地看到半结晶膜的微晶结构。使用傅里叶变换红外 (FT-IR) 和光吸收测试对制备的材料分析官能团的存在和光学响应。使用不同 PVA-β-丙氨酸浓度的聚合物薄膜材料的 Tauc 图计算出的更宽的光学带隙值为 4.89 至 5.07 eV。
