以部分水解聚丙烯酰胺(HPAM)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/HPAM 复合体系。结果表明,当 GO 的加入质量分数为5%时,GO/HPAM 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63.82%；GO 在 HPAM 溶液中能够均匀的分散,并且 GO/HPAM 复合体系的稳定性较好,稳定性参数 TSI 值在2.1附近不再变化；GO/HPAM 复合体系与单一的 HPAM 溶液均为假塑性流体,GO/HPAM 复合体系更接近牛顿流体,黏度更大,并且 GO/HPAM 复合体系的抗剪切性能要比单一的 HPAM 溶液要好；在不同的温度下,GO/HPAM 复合体系的黏度均高于 HPAM 溶液。

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.
