摘要:
采用一步溶液浸渍法制备PDMS/SiO2/PVDF/KH-550超疏水铜网,并考察成膜条件与浸涂液组分含量对涂层疏水性能及表面形貌的影响。结果表明,超疏水铜网的最佳成膜条件为:将铜网在浸涂液中浸泡5 min,以0.05 mm/s的速度提拉成膜,80 ℃下固化2 h。浸涂液的最佳组成为2.5 g PDMS(m(PDMS-A):m(PDMS-B)=10:1),3.125 g SiO2,1.73 g PVDF与0.433 g KH-550,加入50 mL甲苯。制备的超疏水铜网的接触角可达160.1°,滚动角达到2.5°,并具有优异的力学稳定性。
Abstract:
A one-step dip-coating method was used to prepare the PDMS/SiO2/PVDF/KH-550 superhydrophobic copper mesh,and the formation conditions and component contents which affected the superhydrophobic properties and surface morphologies were explored.The results show that the best coating preparation condition is as following:the copper mesh is dipped into the dipping solution for 5 min,lifted up at a velocity of 0.05 mm/s,and then cured at 80 ℃ for 2 h.The optimal dipping solution is prepared by resolving 2.5 g PDMS,3.125 g SiO2,1.73 g PVDF and 0.433 g KH-550 into 50 mL toluene.The formed superhydrophobic mesh has a contact angle of 160.1° and a sliding angle of 2.5°,and exhibits a good mechanical stability.
