用于润湿性控制的Stavax钢基材的皮秒激光表面纹理处理
|
摘要
在本文中,笔者采用皮秒激光来制造Stavax钢基板的表面纹理,此钢基板为制造各种高分子聚合物产品模具的关键材料。在Stavax钢基板上主要有3种类型的表面纹理:周期性波纹、微凸块的双尺度分层二维阵列以及有纳米波纹的微坑阵列。经激光处理后的Stavax钢基板表面的润湿性从其原始的亲水性转变为疏水性,甚至在暴露于空气后具有超疏水性。研究结果清晰地表明,此超疏水性主要是由于表面纹理造成的。超快激光诱导的催化效果可能在改变表面化学性质方面起到次要作用,从而降低了表面能。随后,将金属磨具表面上的经激光处理的表面纹理通过高分子聚合物注射成型工艺复制到聚丙烯基底。由此,聚丙烯模具表面的润湿性从原始的亲水性变成疏水性。此开发工艺在改善塑料制品的湿润控制性和易清洗性方面具有一定潜能。
In this investigation, a picosecond laser was employed to fabricate surface textures on a Stavax steel substrate, which is a key material for mold fabrication in the manufacturing of various polymer products.Three main types of surface textures were fabricated on a Stavax steel substrate: periodic ripples, a two-scale hierarchical two-dimensional array of micro-bumps, and a micro-pits array with nanoripples. The wettability of the laser-textured Stavax steel surface was converted from its original hydrophilicity into hydrophobicity and even super-hydrophobicity after exposure to air. The results clearly show that this super-hydrophobicity is mainly due to the surface textures. The ultrafast laserinduced catalytic effect may play a secondary role in modifying the surface chemistry so as to lower the surface energy. The laser-induced surface textures on the metal mold substrates were then replicated onto polypropylene substrates via the polymer injection molding process. The surface wettability of the molded polypropylene was found to be changed from the original hydrophilicity to superhydrophobicity. This developed process holds the potential to improve the performance of fabricated plastic products in terms of wettability control and easy cleaning.
