摘　　要：介绍了利用低能离子注入聚醚砜 (PES)薄膜进行光学、电学性能改性的研究。实验结果表明 ,注入后 PES薄膜的光吸收性和表面电导率都发生变化 ,苯环大 π键上的激发态与基态之间的能隙随注入剂量的增加而降低 ;薄膜表面电导率提高 4个数量级。通过对样品的红外光谱分析 ,讨论了聚醚砜薄膜在离子注入前后的结构变化。Investigation of optical and electrical property of polysulfone(PES) thin film implanted by low energy ions has been carried on, the result shows that: the energy gap between excited state and base state of π bond decreases with the increase of the dose of implantation. It is found that the sheet conductivity of PES can be increased. By means of infrared spectrum analysis, the change of the structure of the PES sample under different conditions has been investigated.
