Abstract

Abstract: The phase behavior of biomolecules containing persistent molecular entities is generally limited due to their characteristic size that exceeds the intermolecular force field. Consequently, favorable properties normally associated with the liquid phase of a substance, such as fluidity or processability, are not relevant for the processing of biomolecules, thus hindering the optimal processing of biomolecules. The implied problem that arises is how to convert folded biomolecules to display a richer phase behavior. To alleviate this dilemma, a generic approach to liquefied polysaccharides‐based polymers is proposed, resulting in a polysaccharide fluid with a tunable condensed state structure (solid‐gel‐liquid). Polysaccharide biobased fluids materials transcend the limits of the physical state of the biobased material itself and can even create completely new properties (different processing methods as well as functions) in a variety of polymeric structures. Considering the solvent incompatible high and low‐temperature applications, this method will have a great influence on the design of nanostructures of biomolecular derivatives and is expected to transform biomass materials such as polysaccharide biopolymers from traditional use to resource use, ultimately leading to the efficient use of biomass materials and their sustainability. Abstract : Liquid polysaccharides polymer prepared by diffusion‐electrostatic assembly has excellent processing performance and antibacterial activity. In this way, the biomolecules can switch freely between solid–gel–liquid phase by simple adjustment, realizing various processing methods.
