Abstract

Due to their intrinsic biocompatibility and biodegradability, biopolymer-based composite materials have a wide range of potential applications in the biomedical, pharmaceutical, environmental, bio-catalytic, and bio-electronic domains. Ionic liquids can be used as solvents to construct biopolymers such proteins and polysaccharides into a variety of morphologies, including moulded objects, films, fibres, and beads. The procedures for creating biopolymerbased composite materials by employing ionic liquids are outlined in this article. Ionic liquids are used to dissolve the biopolymer, an anti-solvent is used to regenerate the biopolymer, forms are formed, and the regenerated biopolymer is dried. The fabrication and use of composite materials based on biopolymer blends that contain two or more biopolymers are specifically discussed.
