摘要
Anorganicsilaneacrylateresin（PMBK）wassynthesizedbyfree-radicalsolutionpolymerizationusingmethylmethacrylate,butylacrylateand（3-methacryloxypropyl）trimethoxysilaneasmonomers.Aluminum（Al）particleswerethenencapsulatedininorganic-organichybridfilmsthatwerepreparedbyhydrolysisandcondensationofPMBKandtetraethylorthosilicate（TEOS）onthesurfaceofAlpigments.CharacterizationresultsshowedthatPMBKandTEOScouldsimultaneouslyhydrolyzeandcondensewithhydroxylgroupsonthesurfaceoftheAlparticlestoformcompositeAlparticlescoatedwithinorganic-organichybridfilms.ComparedwithrawAlparticles,thecorrosionresistanceandadhesivepropertiesofpaintfilmscontainingthecompositeAlparticleswereimprovedgreatly,whiletheglossinessofthepaintfilmsdecreasedslightly,from48.6°to47.0°.Inalkalinemedia（pH11）,thevolumeofevolvedH2ofcompositeAlparticleswasonly3.5mL,whereasthatofrawAlwas83.5mL.TheglossinessofpaintfilmscontainingcompositeAlparticlesdecreasedby1.66%afterimmersioninalkalinemediafor24h,whereasthatofrawAldecreasedby14.82%.Peel-offtestsofthepaintfilmsshowedthatthecompositeparticlesmovedslightlyawayfromthepaintfilms.Incontrast,therawAlparticleswereseriouslydesquamated,suggestingencapsulationofhybridfilmscangreatlyimprovetheadhesivepropertiesofAlparticlesinpaintfilms.
