水性超疏水复合涂料的制备及其机械稳定性
Preparation and Mechanical Stability of Waterborne Superhydrophobic Composite Paint
摘要
Abstract
The work aims to achieve large-scale application of superhydrophobic surface in actual production and life by developing a waterborne superhydrophobic paint featuring in large area,low cost,designability and no organic solvent.With nanoscale fumed silica and waterbome fluorocarbon resin as main raw materials,and water as solvent,a superhydrophobic paint having self-cleaning effect was fabricated based upon fluorosilane hydrophobic modification.The paint was characterized with field emission scanning electron microscope,contact angle measuring instrument,time-lapse shooting and so on.The waterborne paint could be sprayed on various soft and hard surfaces to obtain superhydrophobic surfaces,the contact angles were all greater than 150° while rolling angles were all less than 10°.Droplet impingement experiments showed that,for the superhydrophobic paint enhanced by resin,its static contact angle was greater than 150° while its rolling angle was below 10° after continuous impingement by 600 mL droplet (total volume).After grinding with sandpaper for 40 cycles,droplets could still fall off their surface.A cheap waterborne superhydrophobic paint with water as main solvent is developed,which can be sprayed to various soft or hard substrates to obtain uniform superhydrophobic coatings.Mechanical stability of the coatings can also be effectively enhanced by adding waterborne resin.关键词
