摘　　要：应用ARE-RFS溶体/熔体旋转流变仪研究了UHMWPP/UHMWPE冻胶体系的动态流变行为。结果表明:体系的储能模量、损耗模量随着角频率及UHMWPE含量的增加而升高;耗散系数随着角频率的增大而降低,随着UHMWWPE含量的增加而降低;复数粘度随着角频率的提高而降低,随着UHMWPE含量的增加而增加。The dynamic rheological behavior of UHMWPP/UHMWPE gel was investigated by means of ARE-RFS rheometer. The results showed that the storage modulus and loss modulus increased with the increase of angular frequency and the concentration of UHMWPE. The loss tangent decreased with the increase of angular frequency and the concentration of UHMWPE. The complex viscosity decreased with angular frequency and increased with the concentration of UHMWPE.
