1.Introduction
Polyaniline(PANI)isanorganicconductingpolymerthathasreceivedextensiveattentionduetoitsuniqueelectricalandopticalproperties.Itiswidelyusedinthefieldsofsensors,batteries,capacitors,andelectronicdevices.However,thepoorprocessabilityandmechanicalpropertiesofPANIlimititspracticalapplications.Toovercometheselimitations,PANIcanbeblendedwithotherpolymerstoformcompositematerials,whichcancombinetheadvantagesofbothcomponents.
Polydichloroethylene(PDCE)isaninsulatingpolymerwithgoodthermalstabilityandmechanicalstrength.BycombiningPDCEwithPANI,thecompositematerialsmayexhibitimprovedelectricalproperties,makingthempotentialcandidatesfordielectricmaterials.

2.1SynthesisofPANI/PDCEcompositematerials
ThePANI/PDCEcompositematerialsweresynthesizedbythesolutionmethod.Firstly,anilinemonomerandPDCEweredissolvedindimethylsulfoxide(DMSO)toformahomogeneoussolution.Thenammoniumpersulfate(APS)wasaddedastheoxidanttoinitiatethepolymerizationofaniline.Thereactionwascarriedoutunderstirringatroomtemperaturefor24hours.Theobtainedcompositematerialswerewashedwithdeionizedwateranddriedinavacuumoven.
2.2Characterization
ThechemicalstructureofthePANI/PDCEcompositematerialswascharacterizedbyFourier-transforminfraredspectroscopy(FT-IR).ThemorphologyanddispersionofPANIinthecompositematerialswereobservedbyscanningelectronmicroscopy(SEM).
