ELECTROSPINNING OF NATIVE CELLULOSE FROM NONVOLATILE SOLVENT SYSTEM

摘要：

Improving and understanding the electrospinnability of native cellulose in room temperature ionic liquids (RTIL) have been a hot issue in recent years. However, it is difficult to create non-derivative cellulose fibrous membranes via electrospinning because it cannot be dissolved in common solvents or melted due to its high crystallinity, which is enhanced by an extensive hydrogen bonding network 1-3. In this study, the electrospinning of cellulose in a highly efficient RTIL of 1-ally1-3-methylimidazolium chloride (AMIMCI) was investigated. The introduction of co-solvent dimethyl sulfoxide (DMSO) 4, which significantly decreased the surface tension and viscosity of the spinning dopes, contributed to a continuous jet, as shown in Table 1.
