Abstract
In thispaper,chemicalandelectrochemicalgraftcopolymerizationofpyrroleonto thiophene-functionalizedpolystyrenemulticentermacromonomer(ThPStM)isdescribed. The polystyrene-g-polypyrrole(PSt-g-PPy) obtainedwascharacterizedbymeansof Fourier transforminfrared(FTIR)spectroscopy,anditselectroactivitybehaviorwas verified undercyclicvoltammetricconditionsinacetonitrile(ACN)–tetraethylammonium tetrafluoroborate(TEAFB)solvent–electrolytecoupleandcomparedwithelectroactivity behavior ofpurepolypyrrole.Electricalconductivitiesofthesamplesweremeasured using samplesinwhichtheconductivematerialsweresandwichedbetweentwoNi electrodes atroomtemperature.Thechemicalcompositionandmolecularweightofthe PSt-g-PPy graftcopolymerweredeterminedbymeansofelementalanalysis,andgel permeationchromatography(GPC),respectively.Moreover,thermalbehaviorsofthe synthesizedpolymerswereinvestigatedbymeansofdifferentialscanningcalorimetry (DSC),andthermogravimetricanalysis(TGA).
