Polymernanotubeshavebeenextensivelyinvestigatedduetotheiruniqueandtunablecompositions,microstrucutes,andsoftproperties,whichhavepotentialapplicationssuchasmoleculardevices,photoelectronicdevices,gassensors9biosensors,catalyses,adsorptionandseparation.Recently,poly(divinylbenzene-co-vinylbenzylchloride)copolymernanotubes(PDV-NT)werepreparedbycationicpolymerization.Herein,ViologensweregraftedtoPDV-NTbythequaternaryammomumreactionwithchloromethylgroupsofpolymernanotubes.TheirphotochromicpropertiesofPDV-NTwerestudied.DuetotheredoxpropertiesofviologengroupsonPDV-NTnaotubes,somePDV@metals(Au,Pt,Au/Pt)compositenanotubeswereinsituobtainedbythereductionofpreviousmetallicions.Effectsofthegraftingratioofviologens,theradiationtimeofUVlight,concentrationofmetallicionsanddifferentcompositemethodsonthemorphologiesofPDV@metalscompositenanotubeswerestudied.Furthermore,compositionsandmicrostructuresoftheas-synthesizedcompositenanotubeswerecharacterizedbyIRspectra,UVspectra,XPS,thermoanalysis,TEMandSEM.thermoanalysis,TEMandSEM. |
