LBL structured chitosan-layered silicate intercalated composites based fibrous mats for protein delivery

► BSA and CS-OREC composites were LBL immobilized on fibrous mats. ► OREC introduction enlarged the average diameter of LBL films coating. ► CS-OREC intercalated structure could enhance the protein loading capacity. ► Doubling the coating bilayers could improve the BSA loading capacity. ► OREC could affect the protein release properties of LBL films coating.
