Abstract Ultralow water adhesion aluminum surface has been fabricated by eco friendly low pressure processing technique. The laser patterned surface shows interconnected spongy porous nanostructures with micro packets at regular intervals. The micro volume of air present inside the interconnected porous surface structure together with the adsorbed hydrocarbons by low pressure processing leads to ultralow water adhesion surface. Application of bigger droplet volumes to the patterned surface showed a decrease in static contact angle measurement due to larger radius of curvature and axisymmetrical compared to the smaller droplets.

低压加工激光加工超低水粘附表面

摘要 采用生态友好的低压加工技术制造了超低水粘附铝表面。激光图案化表面显示出相互连接的海绵状多孔纳米结构，其中有规则间隔的微包。存在于互连多孔表面结构内的微量空气与通过低压处理吸附的碳氢化合物一起导致超低水粘附表面。由于较大的曲率半径和轴对称，与较小的液滴相比，将较大的液滴体积应用于图案化表面显示静态接触角测量值降低。
