Preparation and Characterization of Micro-nano Structural Beads and the Super Hydrophobic Micro-nano Structural Coating

摘要

Fly ash, as a raw materials,is used to prepare micro-nano structural beads with the surface modified by using silane coupling agent. The coating of micro-nano structural surface was prepared by using the modified micro-nano structural beads and silicone rubber adhesive. Then the coating surface was dipped in liquid teflon(PTFE) for hydrophobic modification. Scanning Electronic Microscope (SEM) and JC2000C contact angle tester were used to character the coating surface performance. The results show that the average contact angle and rolling angle of the coating surface are measured as 152.9° and 3.4° respectively which means the prepared coating being of super-hydrophobicity.
