Abstract
Marine biofouling has a serious impact on marine facilities, and traditional antifoulants may cause secondary pollution to the ocean. As chlorogentisyl alcohol (3-chloro-2,5-dihydroxybenzyl alcohol, CHBA) is a marine natural product with excellent antifouling properties, CHBA and its analogues are prepared and combined with silicone-modified polyurethane (SiPU) for development of potential green composite coatings for marine antifouling. Lubricant polydimethylsiloxane and antifoulant CHBA endow the composite material with antifouling properties under dynamic and static conditions, respectively. CHBA is steadily released from the composite coating at a rate of 28 μg/(cm2·d). As one of the CHBA/SiPU composite coatings, SiPU-3 exhibits inspiring activities against Escherichia coli (Gram-negative bacteria), Staphylococcus aureus (Gram-positive bacteria) and Vibriofischeri (marine bacteria), with all inhibition rates exceeding 90.0 %. This composite coating has high antiprotein adsorption ability and algal inhibition rate, showing desirable antifouling performance for up to 90 d in seawater. This work will provide new possible considerations in the development of marine antifouling coatings using marine natural antifoulants.
期刊介绍:
The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as:
• Chemical, physical and technological properties of organic coatings and related materials
• Problems and methods of preparation, manufacture and application of these materials
• Performance, testing and analysis.
