【摘要】 采用Bohlin Gemini HR Nano 200溶液旋转流变仪对用于制备胶原蛋白/壳聚糖复合纤维的纺丝液的流变性进行了研究,结果表明,复合溶液属于非牛顿流体中的假塑性流体。表观粘度随复合浓度的升高而升高。随原液浓度的提高,温度对表观粘度的影响越小。原液的结构化程度随体系温度上升,复合浓度下降而减少。更多还原

【Abstract】 The rheology of coUagen/chitosan composite spinning solution had been studied by the Bohlin Gemini HR Nano 200 solution rheometer in this paper.The results showed that composite solution was a pseudoplastic fluid belonged to non-Newtonian fluid. The viscosity and the effect of temperature on the viscosity is increased with the increasing concentration.The extent of structured dope is decreased with elevating the temperature and reducing the concentration.更多还原
