舰船高性能防腐蚀防污涂料研究进展 总被引:1,自引:0,他引:1
简要论述了海洋防腐蚀防污涂料的发展历史和研究现状,重点论述了舰船高性能防腐蚀防污涂料的最新研究进展。有机锡自抛光防污涂料被禁止使用之后,基于丙烯酸锌、丙烯酸铜和丙烯酸硅烷酯的自抛光防污涂料得到了广泛应用。基于含防污功能基团树脂的防污涂料、基于降解树脂的防污涂料以及基于表面结构特性的防污涂料技术成为当前防污涂料研究的热点。文中详细报道了降解树脂的结构对降解性能及力学性能影响规律,以及表面结构特性对污损释放型防污涂料防污性能的影响规律。随着环境保护法规的日趋严格,防腐蚀涂料向无溶剂(或高固体)、长效方向发展。报道了提高涂层的湿态附着力和致密性的方法,采用该方法可以大幅提高涂层的力学性能和耐蚀性能,满足了远洋和深海装备发展需求。 相似文献

Superdurable Coating Fabricated from a Double‐Sided Tape with Long Term “Zero” Bacterial Adhesion 下载免费PDF全文
There is no coating technology currently available to prevent the notorious biofilm formation issue. Here, a potential solution to fully address this tough issue is reported by developing a super‐antifouling coating. The use of zwitterionic hydrogel (a double‐sided tape) and commercial superglue is combined and a durable and ultrarobust antifouling zwitterionic (DURA‐Z) coating is created that can be easily and universally applied on common substrates. Commercial superglue mostly for binding hydrophobic materials is used to strongly immobilize the superhydrophilic DURA‐Z coating through interpenetration. DURA‐Z coating effectively solves several key challenges preventing the current antifouling coatings from practical use, including difficult fabrication, low efficacy, poor toughness, and durability. The fabricated DURA‐Z coating retains antifouling property after 90 d of immersion in water, 50 d of buffer shearing, and 30 d of water flushing, and after repeated knife scratch and sandpaper abrasion under 570 kPa. The DURA‐Z coating achieves a rarely reported long‐term biofilm resistance to both Gram‐positive and Gram‐negative bacteria and fungi: it remains almost “zero” microbe adhesion after continuously challenged by more than 109 cells mL?1 culture medium for 30 d. 相似文献

Marine biofouling is a major issue deteriorating the service performance and lifespan of marine infrastruc-tures.The development of a durable,long-term,and environment-friendly antifouling coating is therefore of significant importance but still a critical challenge in maritime engineering.Herein,we developed a Cu-Ti composite antifouling coating with micron-sized alternating laminated-structure of Cu/Ti by plasma spraying of mechanically mixed Cu/Ti powders.The coating was designed to enable controlled release of Cu ions through galvanic dissolution of Cu laminates from the Cu/Ti micro-galvanic cell in aqueous solution.Results showed that remarkable antifouling efficiency against bacterial survival and adhesion up to ~100 % was achieved for the Cu-Ti coating.Cu/Ti micro-galvanic cell was in-situ formed within Cu-Ti coating and responsible for its Cu ions release.The successive dissolution of Cu laminates resulted in the formation of micro-channels under Ti laminates near surface,which contributed to controlled slow Cu ions release and self-polishing effect.Thus,environment-friendly antifouling capability and ~200 %longer antifouling lifetime than that of the conventional organic antifouling coatings can be achieved for the Cu-Ti coating.On the other hand,as compared to the conventional organic antifouling coatings,the Cu-Ti composite coating presented much higher mechanical durability due to its strong adhesion strength,excellent mechanical properties,and two orders lower wear rate.The present laminated Cu-Ti coating exhibits combination of outstanding antifouling performance and high mechanical durability,which makes this coating very potentially candidates in marine antifouling application. 相似文献
