| 논문초록 | To overcome the drawbacks of the UV grafting method, thermal grafting process is suggested. The uniform and geometry-independent grafting of zwitterionic polymers on curved cross-linked polyethylene(CLPE) surface was successfully achieved. The thermal method yielded zwitterionic surfaces with similar hydrophilicities and graft layer thicknesses to those prepared via the UV grafting method. The XPS data showed that the zwitterionic layers were successfully grafted onto the CLPE surface. 3D confocal microscopy, friction tests, and wear tests, confirmed that there was a significant decrease in the friction coefficient and wear. The thermally grafted polymer brushes showed uniform graft layer thickness on the curved CLPE surface, whereas the UV-grafted brushes showed a geometry-dependent heterogeneous graft layer thickness. Thus, we confirmed that the thermal grafting method is advantageous for the preparation of uniform grafting layers on artificial joint surfaces with complicated shapes. |
