Antistatic Pvc Material

Tetrapod-like zinc oxide whiskers(T-ZnOw) and alumininum doped zinc oxide(AZO) nanopowders were successfully prepared by carbon reduction and the sol-gelmethod, respectively. In addition, antimony doped tin oxide(ATO) nanopowders weresynthesized separately using the hydrothermal method and coprecipitation. The structureand morphology of the products were investigated by X-ray diffraction (XRD), UV-vis,Raman, Energy Dispersive Spectroscopy(EDS), Transmission Electron Microscope(TEM) and Scanning Electron Microscopy (SEM). Futhermoe, different synthesizingmethods, doping alumininum(or antimony) content, reaction temperature, annealingtemperature and annealing time effects on the powders' structure and resistivity.Powders/PVC composite materials were prepared, and the surface resistivity wasmeasured with high resistance apparatus. Comparison of the results showed that ATOnanoparticles had the best antistatic ettect on PVC, T-ZnOw took the second place. ATOnanoparticles prepared by coprecipitation had better antistatic effect on PVC than thoseprepared by the hydrothermal method. Particles showed better antistatic effect on PVCafter being modified by the appropriate coupling agent. The results also showed that thedoping concentration, reaction temperature and the content of the conductive powders inthe composite materials effected the antistatic properties of PVC.Polyaniline(PANI) was respectively coated on zinc oxide and antimony doped tinoxide nanoparticles. The products were investigated by XRD, Thermal GravityAnalysis(TG), Fourier-Transform Infrared Spectrography (FT-IR), TEM and SEM. Theconductivity of PANI/ATO nanoparticles was greatly enhanced via doping hydrochloricacid.
