摘要
In this work, graphene oxide (GO)/polyamide 6 (PA6) nanocomposites with different graphene content (0.03-0.5 wt%) were prepared via in situ polymerization of GO and e-caprolactam. The linear and nonlinear rheological properties and thixotropy of GO/PA6 nanocomposites are investigated using steady state, dynamic, and transient rheological method with a Haake plate rotary rheometer. Cox/Merz rules and Cross model were used to fit the shear rate sweep and dynamic frequency sweep data, and a wider range(10(-2)-10(4) s(-1)) of flow curve was obtained. The results show the PA6 and GO/PA6 melts are shear thinning fluid without yield stress, and have thixotropy. Highlights . Dynamic, steady, and transient rheological tests were performed. . Cox/Merz rules and Cross model were used to fit the data. . A wider range(10(-2)-104 s(-1)) of flow curve was obtained.
