Background technology
Under water, on the basal surface of various matrix, attachment and the growth of various organic life entity (such as microorganism, sea lettuce, barnacle etc.), breed and all bring many drawbacks, this phenomenon is referred to as biodeterioration.Such as, biodeterioration in marine environment can cause that naval vessels energy consumption increases, the speed of a ship or plane reduces, efficiency reduces, and the increasing the weight of etc. of various corrosion.No matter from civilian, commercial or military, marine anti-pollution problem is all important topics of ocean engineering.Marime fouling is a huge obstacle for marine industry, therefore scholars be all devoted to research can realize effectively antifouling coating.On the basis of nonpolluting coating, can better realize raising the efficiency, saving earth resource and environmental protect pollution problem by the technology of drag-reducing coating.
For the requirement of current marine anti-pollution and drag reduction aspect, current drag reduction means mainly comprise the low-surface-energy super-hydrophobic coat of imitative lotus leaf, the flexible coating of imitative dolphin, and the polymeric coating layer of imitative mucus etc.But the prerequisite that these drag-reducing coatings are applied to marine systems needs good anti-fouling effect.And antifouling for marine organisms, current main countermeasure comprises chemical preservation method, physics anti-fouling method and bioantifouling method.Wherein chemical method comprises employing contact-type, lysotype and the nonpolluting coating from polishing type, wherein the most effectively from tributyl tin (TBT) coating of polishing type, but to environment aspect, there is high risks due to it, forbidden by international legislation at present.Thus derive other chemistry (poisoning) anti-fouling method various, such as, replace containing tin coating etc. with the compound of copper, the compound of zinc.But all kinds of chemical method always produces harmful effect to environment, and it is extremely important for therefore studying nontoxic and effective wide spectrum antifouling.For this reason, scholars, on the one hand from material angle, hopes and by low-surface-energy material, attachment is rinsed under flow action; On the one hand from physical angle, undertaken antifouling by the mode such as electrolysis or radiation, or undertaken antifouling by physical characteristic such as roughness, surface topography, hydrophobicity, the zeta current potential etc. changing material surface; Last aspect is from biological angle, purify various biological metabolite or enzyme thus suppress biodeterioration.Presently, physical method still rests on laboratory stage, and lacks relevant theoretical direction.And although biological method such as enzymatic isolation method has more antifouling potentiality, it still lacks the experimental evidence of application aspect.Therefore, nontoxic in desirable meaning and the effective antifouling means of wide spectrum wait research and development.
Drag reduction aspect under water, current main countermeasure comprises submissive wall drag reduction, hydrophobic surface drag reduction, drag reduction by riblets, retinue wave surface drag reduction etc.But most drag reduction technology or be limited by traditional manufacturing process, or be only limitted to the service condition of low flow velocity and fluid channel, all cannot obtain commercial Application widely.Therefore, processing technology is simple, and with low cost and effective drag reduction means wait research and development.
