Abstract: The graphene oxide (GO) is dispersed in HPAM which is served as the matrix, and GO/HPAM composite system is prepared by physical blending method. The laboratory evaluation experiment shows that: when the amount of GO accounts for 5% of HPAM, the viscosity of GO/HPAM composite system is maximum, and the addition of GO making the viscosity of the composite system increase by nearly 63.82%.GO can be uniformly dispersed in the HPAM solution, and the stability of GO/HPAM composite system is quite good. Stability parameter TSI adds up to about 2.1 and then doesn’t change any more. GO/HPAM composite system and the single HPAM solution are both pseudoplastic fluid, but GO/HPAM composite system is closer to the Newton fluid with better viscosity and shearing resistance. Under the different temperature, the viscosity of composite system of GO/HPAM is higher than that of HPAM solution.

摘要： 以部分水解聚丙烯酰胺( HP AM) 为基体, 将氧化石墨烯( GO) 分散在基体中, 采用物理共混法制备 GO /HP AM 复合体系。结果表明, 当GO的加入质量分数为5%时, GO /HP AM 复合体系的黏度最大, GO的加入 使得复合体系的黏度提高了将近6 3. 8 2%; GO在 HP AM 溶液中能够均匀的分散, 并且GO /HP AM 复合体系的稳定 性较好, 稳定性参数T S I值在2. 1附近不再变化; GO /HP AM 复合体系与单一的 HP AM 溶液均为假塑性流体, GO / HP AM 复合体系更接近牛顿流体, 黏度更大, 并且 GO /HP AM 复合体系的抗剪切性能要比单一的 HP AM 溶液要 好; 在不同的温度下, GO /HP AM 复合体系的黏度均高于 HP AM 溶液。
