In this paper, phosphorus graphene oxide/poly (vinyl alcohol) polymer (PGO/PVA polymer) was synthesized by PGO and PVA via the esterification in the case of faint acidity and the ultrasound irradiation and characterized; moreover, phosphorus graphene oxide/poly (vinyl alcohol) film (PGO/PVA film) was prepared by PGO/PVA polymer and characterized; also, the surface resistivity of PGO/PVA film was investigated in the case of the different amount of PGO. Based on those, it had been found that PGO reacted with PVA to produce PGO/PVA polymer via the esterification under the ultrasonic-assisted condition, and PGO/PVA polymer was structured by 2D lattice of PGO and the chain of PVA connected in the form of six-member lactone ring and phosphonic ester, and PGO/PVA film was constituted by PGO/PVA polymer, and surface resistivity of 0.00, 0.75, 1.50, 2.25 and 3.00wt% of PGO/PVA film were 6.85×10, 2.98×10, 1.42×10, 7.66×10 and 1.29×10Ω/sq, respectively.
本文通过在弱酸性条件下和超声辐照下，使磷氧化石墨烯（PGO）与聚乙烯醇（PVA）发生酯化反应合成了磷氧化石墨烯/聚乙烯醇聚合物（PGO/PVA聚合物）并对其进行了表征；此外，用PGO/PVA聚合物制备了磷氧化石墨烯/聚乙烯醇薄膜（PGO/PVA薄膜）并对其进行了表征；还研究了不同PGO用量情况下PGO/PVA薄膜的表面电阻率。基于此，发现PGO在超声辅助条件下与PVA通过酯化反应生成PGO/PVA聚合物，PGO/PVA聚合物由PGO的二维晶格和以六元内酯环及膦酸酯形式连接的PVA链构成，PGO/PVA薄膜由PGO/PVA聚合物组成，PGO含量为0.00、0.75、1.50、2.25和3.00wt%的PGO/PVA薄膜的表面电阻率分别为6.85×10、2.98×10、1.42×10、7.66×10和1.29×10Ω/sq。
