Nowadays, the importance of green and biodegradable plastics as viable substitutes for non-degradable petroleum-based materials is felt more than ever. Regenerated cellulose (RC) as a potential candidate suffers from poor processability and inferior properties, limiting its wide applications. In this study, it is demonstrated that citric acid (CA) enhances phys., mech., and thermal properties of RC films, due to RC-citric acid compatibility. 1-Ethyl-3-methylimidazolium chloride (EMIMCl) as a green ionic liquid was employed for the processing of RC. The optimum properties in terms of thermal stability, mech. strength, contact angle, water uptake, and oxygen permeability were achieved at 10 wt% of CA. However, further incorporation of CA adversely affected the film properties. This behavior was explained by the crosslinking and plasticizing effects of CA. Furthermore, in vitro cytotoxicity test demonstrated that RC/CA films are cytocompatible, suggesting the potential advantage of using these biopolymeric films for biomaterial and biol. applications.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.
1-Ethyl-3-methyl-1H-imidazol-3-ium chloride(cas: 65039-09-0) is an imidazolium chloride ionic liquid that can be used as:a solvent as well as catalyst for the depolymerization of oak wood lignin; a solvent in the hydrolysis of hemicellulose (xylan) to xylose using Brønsted acid catalysts.Category: imidazoles-derivatives
