Blends of Cellulose and Silk Fibroin in 1-buthyl-3-methylimidazolium chloride- Based Solutions

Abstract

Cellulose/fibroin blends in 1-buthyl-3-methylimidazolium chloride-based solutions (BMIMCl) were studied using TGA, IR-spectroscopy, X-Ray and viscometry methods. The strongest intermolecular interaction occurred with 20% fibroin in the blend. As a result an amorphous and homogeneous film structure was formed. The solution of this blend has the highest viscosity than those obtained from not mixed solutions.
