摘要
A 25 μm thick polystyrene (PS) film was implanted with 120 keV ions of carbon to doses of 1 × 1014, 1 × 1015, 3 × 1015, 5 × 1015 and 1 × 1016 ions cm-2, respectively. The structure of the implanted PS was characterized by X-ray photoelectron spectroscopy (XPS), whereas the friction and wear behaviour of both implanted and unimplanted PS were investigated using an one-way reciprocating friction tester against a steel ball. Friction results indicate that ion implantation at a dose of 1 × 1014 ions cm-2 increases friction coefficient, whereas the ion implantation at a dose of 1 × 1015 ions cm-2 or higher decreases friction coefficient, and all the tests show that ion implantation lowers wear rate. XPS analyses reveal that ion implantation at dose of 1 × 1014 ions cm-2 results in partial break of benzene ring, and at a dose of 1 × 1016 ions cm-2 results in complete break of benzene ring.
