摘要:以石墨粉和三氯化钛为原料,通过Hummers和水解法制备得石墨烯/二氧化钛(G/TiO2),将G/TiO2作为填料添加到聚氯乙烯(PVC)中,探究其对PVC薄膜性能的影响。结果表明,添加G/TiO2提高了PVC薄膜的力学性能、抗静电性能和耐紫外老化性能。添加G/TiO2的PVC薄膜的拉伸强度由纯PVC薄膜的12.79 MPa提升至22.74 MPa,提高了77.80%,断裂伸长率由77.73%提升至98.23%,提高了26.37%,表面电阻由大于1.034×1012 Ω降低至8.156×105 Ω,达到抗静电材料要求;经过150 h紫外老化后,纯PVC薄膜的拉伸强度由12.79 MPa降低至8.49 MPa,下降了33.62%;添加G/TiO2的PVC薄膜的拉伸强度由22.74 MPa降低至18.54 MPa,仅下降18.64%。 
Abstract:Graphene/titanium dioxide (G/TiO2) was prepared by Hummers and hydrolysis method using graphite powder and titanium trichloride as raw materials. G/TiO2 was added as a filler to polyvinyl chloride (PVC), and the effects of G/TiO2 on PVC film performance were studied. The results show that the addition of G/TiO2 improves the mechanical properties, antistatic performance and ultraviolet aging resistance of PVC film. The tensile strength of PVC film with G/TiO2 increases from 12.79 MPa of pure PVC film to 22.74 MPa, increases by 77.80%, and the elongation at break increases from 77.73% to 98.23%, increases 26.37%, and the surface resistance is reduced from>1.034×1012 Ω to 8.156×105 Ω, which meets the requirements of antistatic materials. After 150 h UV aging, the tensile strength of pure PVC film decreases from 12.79 MPa to 8.49 MPa, decreases by 33.62%, the tensile strength of PVC film with G/TiO2 decreases from 22.74 MPa to 18.54 MPa, only decreases by 18.64%.
