Bydirectly mixing or chitosan microsphere embedding in two ways with FPA-SPUhybrid coatings mixing successfully constructed four antifouling agent releasecoating type, four groups antifouling agent release on the physicochemicalproperties of coating type and controlled release properties was studied. Bycarrying enzyme preparation of mesoporous material hole and FPA-SPU resincomposite was successfully constructed, and 4 kinds of enzyme load typeantifouling coating to study its physicochemical properties. To FPA-SPU base,by adding different kinds of different viscosity silicone oil, weresuccessfully prepared seven different types of silicone oil exudativeantifouling coating and a self polishing coating material, explore thedifferent silicone oil formation in the coating of oil storage bursa size,dispersion degree, shape and seeping the sustained release effect.
Theanti fouling properties of 20 kinds of 5 kinds of bionic anti fouling coatingswere discussed by the combination of microbial experiment and hanging plateexperiment. Through training the n.pinna, Fuji Suke larvae, attachment anddesorption experiment and test prepared by different types and differentparameters of antifouling coating inhibition of microbial attachment rate.Comparison between the two groups showed that: imitation is built based on thelow molecular weight of methyl silicone oil or phenyl silicone oil and FPA-SPUsubstrate permeability type antifouling coating anti diatom adhesionperformance was the best, followed by lysozyme load group, horseradishperoxidase (HRP) group and micro structure type antifouling coating. Diatom dedesorption experiments showed that most favor diatoms desorption for the use oflow molecular weight silicone fluid and FPA-SPU substrate construct imitationinfiltration type antifouling coatings, alkaline protease load group and amicro structure type antifouling coating (SiO2-3 group). The
Barnaclelarvae attachment experiment results confirm that release 3 phenyl silicone oilexudative, two bit type antifouling coating performance was the best, followedby a low molecular weight silicone exudative (201-100 group), lysozyme groupand Cap-CSM group。 Sea hanging plate results show that, in exudative coating,add the phenyl silicone oil, hydroxy silicone oil is more effective than methylsilicone oil, more conducive to inhibit the attachment of fouling organisms（www。gfanyingfu。com/）。 Inthe same class of silicone oil viscosity on the fouling adhesion influences therate of relative。 In micro structure type, antifouling agent release, enzymeload and low surface energy 4 12 kinds of coating, anti fouling agent releasetype antifouling performance was the best, followed by enzyme load type andmicro structure type antifouling coating。 However, compared with the generalfluorocarbon resin and poly two methyl silicone resin, 20 kinds of bionic antifouling coatings have good performance of microbial fouling。
