用120 keV的氮离子注入50 μm厚的聚酰亚胺（PI）薄膜，注入剂量分别为5 × 1014 ions cm-2和5 × 1016 ions cm-2。采用X射线光电子能谱（XPS）和红外光谱（FT-IR）对改性前后PI的结构进行了表征，并利用单向往复摩擦磨损试验机研究了改性前后PI的摩擦磨损性能。结果表明，氮离子注入降低了摩擦系数和磨损率，特别是当注入剂量为5 × 1016 ions cm-2时。XPS和FT-IR分析表明，氮离子注入过程中形成了CN键交联。
A 50 μm thickness polyimide (PI) film was implanted with 120 keV nitrogen ion to doses of 5 × 1014ions cm−2and 5 × 1016ions cm−2. The structure of the treated PI was characterized by X-ray photoelectron spectroscopy (XPS) and reflecting Ft-IR, whereas the friction and wear behaviors of both implanted and unimplanted PI were investigated using a one-way reciprocating friction tester against a steel ball. Results indicate that nitrogen ion implantation decreases friction coefficient as well as wear rate, especially for the dose of 5 × 1016ions cm−2. XPS and FT-IR analyses suggest the formation of cross-linking with CN bond during the process of nitrogen ion implantation.
