离子注入聚乙炔表面改性研究中红外光谱的应用

The use of IR spectroscopy in surface modification study of polyacetylene film by ion implantation

运用傅里叶变换红外光谱法(FTIR)和衰减全反射-傅里叶变换红外光谱(ATR-FTIR)技术测量和比较由不同合成方法制得的聚乙炔膜在空气中的氧化行为,观察稀土聚乙炔膜K^+离子注入前后表面和本体红外光谱的变化,同时讨论了离子注入对聚乙炔膜结构和性能的影响.

The kinetics of oxidation of two kinds of polyacetylene film (R - PA and N - PA) exposed to air at about 20℃ and 45% relative humidity have been established and the changes in the structure of R - PA film before and after ion implantation were examined by FTIR and ATR - FTIR spectroscopy. It was observed that IR spectra of implanted K+ion R - PA film is different from these of chemically doped and the radiation stability of cis -(R -PA) film is better than trans -(R -PA). The relation between changes of the structure of surface layers during ion implantation for doping of polyacetylene and electrical properties have been discussed preliminarily.
