摘　　要：用付里叶变换红外光谱研究了３６０ｋｅＶＡｒ^（３＋）离子辐照聚碳酸酯薄膜的化学结构变化。氩离子辐照剂量为１．３×１０^（１２）～６．５×１０^（１３）离子／ｃｍ~２。结果表明，化学降解是聚碳酸酯薄膜主要的结构变化。此外，氩离子辐照也形成了ＯＨ基团、新的羰基团和碳化。A fourier transform infrared (FTIR) spectroscopic investigation of the ion-beam-induced chemical and structural modification in polycarbonate (PC) films is prasented. It is found that chemical structure in PC is subjected to a severe degradation within the dose range from 1. 3×10￣(12) to 6. 5 ×10￣(13) Ar￣(3+) cm￣(-2). Furthermore, irradiation results in OH groups, new carbonyl groups and carbonization. It is suggests that chemical bonds dissociation and rearrangement are responsible for the above facts.
