Evaluation of Electrospinnability of Celluloses Derived from Different Biomass Resources

Abstract

Electrospinnability as well as dissolvability of the celluloses derived from different biomass resources are systematically studied in this work. By analyzing the essentially physical and molecular structure of cellulose in detail, dissolving efficiency and molecular chain entanglement in solution of cellulose are carefully realized. Accordingly, the original factors on electrospinnability of cellulose is revealed. Crystallinity mainly affects the dissolution of cellulose, which is the foundation to achieve electrospinning. Degree of polymerization is the decisive index of cellulose to form molecular entanglement in solution or not. Proper molecular entanglement of cellulose, just as corn cellulose II, could initiate the formation of ultrafine fiber with good morphology in electrospinning. Our research is no doubt helpful to establish a solid scientific and technical foundation for selection of cellulose to achieve high efficiency fabrication of ultrafine fiber in electrospinning.
