摘　　要：针对激光刻蚀的金属表面短期内的超亲水性及较长的润湿性转变周期问题,通过优化飞秒激光刻蚀参数在紫铜表面构造出微/纳米分层的乳突状结构,制备了超亲水样品。样品在水汽环境下高温热氧化3 h后,放置于150℃的管式炉中用乙醇辅助退火15 min,测得其表面水接触角由退火前的(4.0±0.7)°提高到(150.7±0.6)°,样品表面由超亲水快速转变为超疏水,极大提高了润湿性转变效率。Aiming at the problem of short-term superhydrophilicity and long wettability transition period of laser etched metal surface,we optimized the laser etching parameters to construct micro/nano layered papillary structures on the surface of red copper,and manufactured the superhydrophilic samples.After being thermally oxidized for 3 h at high temperature under water vapor environment,the samples were annealed with ethanol for 15 min in a 150 ℃tubular furnace.The water contact angle on the surface of the samples increased from(4.0±0.7)° before annealing to(150.7±0.6)° after annealing,and the sample surface changed rapidly from superhydrophilic to superhydrophobic,which greatly improved the wettability transformation efficiency.
