Bacterial Cellulose-Polyurethane Composite Material, Preparation Method Therefor, and Application Thereof
20220315760 · 2022-10-06 ·

A bacterial cellulose-polyurethane composite material, preparation method, and use are described. The preparation method comprises: performing organic solvent exchange on bacterial cellulose microfibers, and obtaining bacterial cellulose microfiber composite substance A and composite substance B of different concentrations; under oil bath conditions, adding a polymer polyol and a diisocyanate compound and performing an addition polymerization reaction, obtaining, via the reaction, a bacterial cellulose composite polyurethane foam prepolymer; and subsequently performing curing and obtaining the bacterial cellulose-polyurethane composite material. By combining bacterial cellulose microfibers and polyurethane foam material, the mechanical properties of the composite material are significantly improved; the large amount of hydroxyl groups on the surfaces of the bacterial cellulose nanofibers effectively strengthens the hydrophilicity and water absorption capability of the composite material; and the favorable tissue affinity of bacterial cellulose can also improve the biocompatibility of polyurethane material.
