About Cover

3D printing as the state-of-the-art emerging technology offers a platform for the new industrial horizons. The manufacturing process for creating 3D physical objects done via successive layer-by-layer deposition of materials such as metal, plastic, ceramics, or even living cells. The 3D printing concept was first proposed in the 1980s using stereolithography to make polymer objects. 3D technology could transform manufacturing, global product consumption and supply chains. The cover photo of July 2019 issue describes the structure of a 3D printed objects and to celebrate the 39th anniversary of its innovation.

Abstract

Currently, there is a huge demand for the application of superhydrophobic surface in industrial and marine equipment. In this investigation, the hydrophobicity of Q235 steel surface was achieved by implementing micro-patterns on the substrate using laser surface texturing and deposition of nano-copper particles. By controlling the movement of the laser spots, different controlled textures at microscale were fabricated. Via the chelation between the copper species and the catechol moieties on polydopamine (PDA), nano copper was decorated to form the multi-level structure. The surface microstructure, topographies, chemical component and wettability of as-prepared superhydrophobic surface were analyzed systematically. Based on the models built by Wenzel and Cassie–Baxter, the effect of micro texture on contact angle was discussed. This method is expected to have many potential applications including antibacterial materials for the protection of marine equipment.  © VBRI Press.
