Abstract
The use of renewable resources is one convenient path towards functional biomaterials with eco-friendly and biodegradable properties. Cellulose is a widely abundant renewable biopolymer material which can be isolated from biomass resources such as wood tree species and cotton. Cellulose materials exhibit different properties, depending on the resources, processing and applying strategies for modification. The versatile possibilities for tailoring cellulose materials for different applications become more increasingly important to fulfill the society’s further requirements for modern materials. In this context, obtainment of shapeable materials from cellulose has a significant relevance. Ionic liquids are green solvents regularly utilized as dissolving media in polyose-based gels. These ion gels formed by including ionic liquids in the polysaccharide network matrix can be further transformed into valuable sustainable materials (e.g., composite films with good transparency properties) through interchange of solvent media and regeneration processes. During these treatments, cellulose materials are subjected to significant structural crystalline transitions (form I is changed into form II) which are related to the potential further improvement of reducing sugars releasing rate and hydrolysis yield. The present chapter presents some results of our investigations upon usefulness of organic salts with low melting points based on imidazolium cations for enhanced enzymatic saccharification of cellulosic substrates.
