摘要
为探究激光直写制备超疏水PDMS表面的方法,课题组通过激光点阵列直写制备了具有不同粘附力的超疏水表面。使用飞秒激光点阵列扫描在PDMS表面制备微纳结构,通过改变激光功率和扫描点间距实现了不同疏水性和粘附力的超疏水表面。通过对界面润湿状态的分析,研究了表面结构疏水性和粘附性转变的原因。结果表明:使用飞秒激光直写点阵列结构在PDMS上制备超疏水表面是一种有效且可调粘附性的方法。
In order to explore the method of preparing superhydrophobic PDMS surface by laser direct writing,superhydrophobic surface with different adhesion forces was prepared by laser dot array direct writing.Micro and nano structures were prepared on PDMS using femtosecond laser point array scanning,and superhydrophobic surfaces with different hydrophobicity and adhesion were achieved by varying the laser power and scan spacing.The analysis of the interfacial wetting state explains the hydrophobicity and adhesion transition of the surface structures.The results show that the preparation of superhydrophobic surfaces on PDMS using femtosecond laser direct-writting dot array structures is an effective method with tunable adhesion.
