摘要

本报告介绍了在含有 5 mM EDOT 单体和 0.2 M 异丙醇的 N2 饱和水溶液中使用伽马 Co-60 辐射合成导电聚合物聚(3,4-亚乙二氧基噻吩)(PEDOT)的研究结果。伽马辐照来自伽马 Co-60 源,剂量范围为 12 kGy 至 58 kGy。为了评估辐照前后溶液的化学成分,对紫外可见光谱和傅立叶变换红外吸收光谱进行了检测。结果表明,辐照后溶液中形成了黄色悬浮物,紫外可见光谱显示出现了二聚体、低聚物和 PEDOT 聚合物。从辐照溶液中得到的干燥粉末证实了 PEDOT 的成功合成,并在傅立叶变换红外光谱中显示出明显的化学结构特征。这些发现证明了利用伽马 Co-60 辐照可以有效地合成导电 PEDOT 聚合物。

Synthesis of conducting polymer by gamma Co-60 ray in aqueous solution
This report presents the findings of a study on the synthesis of the conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) using gamma Co-60 radiation in an aqueous solution saturated with N2 gas, containing 5 mM EDOT monomer and 0.2 M isopropanol. Gamma radiation with doses ranging from 12 kGy to 58 kGy from a gamma Co-60 source was employed. To assess the chemical composition of the solution before and after irradiation, UV-Vis and FTIR absorption spectra were examined. The results indicated the formation of yellow suspensions in the solution after irradiation, along with the emergence of dimers, oligomers, and PEDOT polymers as evidenced by UV-Vis spectra. The dried powders obtained from the irradiated solutions confirmed the successful synthesis of PEDOT, exhibiting distinct chemical structural characteristics in the FTIR spectra. These findings demonstrate the effective radiation-induced synthesis of conducting PEDOT polymer using gamma Co-60 irradiation.
