Rheological Properties of PAN and Silk Fibroin in Aqueous NaSCN Solutions

摘要

The rheological properties of polyacrylonitrile (PAN) and silk fibroin (SF) in the aqueous NaSCN Solutions were investigated in this study. The results show that the solutions possessed slightly pseudo-plastic solution properties. Their apparent viscosity increased with the increasing total polymer concentration, whereas all of these decreased with the increasing temperature. The viscosity of PAN/SF blend solutions decreased with the increase of the SF component.
