DMSO as an auxiliary solvent in the fabrication of homogeneous chitin-based films obtaining from an ionic liquid process

The novel preparation procedure for the fabrication of homogeneous chitin films has been designed. The method is based on the processing of biopolymers in ionic liquid-based solvents with the assistance of dimethyl sulfoxide co-solvent. In our experiments, co-solvent was added to the chitin solution just before biopolymer regeneration, as a viscosity reducer. The concept of the reduced viscosity allows to realize the easier manufacture of chitin...
