基于微纳米孔洞结构的彩色超疏水不锈钢表面的制备
|
摘要
本文采用电化学活化和化学蚀刻法在304不锈钢表面制备了微纳米复合孔洞结构,再经氟化改性溶液修饰和着色处理分别获得超疏水不锈钢表面和彩色超疏水不锈钢表面。采用扫描电镜、接触角测试仪等研究了活化时间、蚀刻液配比、蚀刻温度、蚀刻时间以及不同着色方法对不锈钢表面微纳米结构的影响。结果表明,化学腐蚀可在不锈钢表面形成均匀的微纳米复合孔洞结构,在此基础上制备的超疏水不锈钢表面的疏水角达155.50°,彩色超疏水不锈钢表面的疏水角为151.83°。
In this work,a micro/nano composite pore structure was fabricated on 304 stainless steel sur-face via electrochemical activation combined with chemical etching. Super hydrophobic stainless steeland super hydrophobic coloured stainless steel surface could be obtained respectively,while after thispore-structured surface was modified by fluorsilane before and after coloring treatment. The effects of ac-tivating treatment time,composition of etching solution,etching temperature,etching time and differentcolouring methods on the micro/nano structure of surface were investigated by scanning electron micros-copy(SEM)and water contact angle measurements. The results show that chemical corrosion could forma uniform micro/nano composite pore structure on the stainless steel surface. The water contact angles ofthe prepared super hydrophobic stainless steel surface and the coloured super hydrophobic stainless steelsurface reached 155.50° and 151.83°,respectively.
