采用激光加工在Ti6Al4V试样表面加工不同间距的点阵结构,采用自组装技术制备4种自组装分子膜.通过表面形貌和接触角的测量表征试样的表面特性.结果表明:通过激光点阵加工和沉积自组装分子膜,可显著增加Ti6Al4V试样的水接触角.长链分子FDTS、FOTS和OTS制备的自组装分子膜,使Ti6Al4V试样的接触角均大于150°,形成超疏水表面,其中沉积FDTS自组装分子膜时,试样的接触角最大,可达164.5°.沉积短链分子MPS自组装分子膜时,只有当激光加工间距为50μm时,试样方可形成超疏水表面;间距增大后,试样表面变成疏水表面.沉积4种自组装分子膜时,试样的接触角均随激光点阵加工间距的增大而减小.
