Bionanocomposites: differential effects of cellulose nanocrystals on protein diblock copolymers.

abstract：:Polymerized high internal phase emulsions (polyHIPEs) have been utilized in the creation of injectable scaffolds that cure in situ to fill irregular bone defects and potentially improve tissue healing. Previously, thermally initiated scaffolds required hours to cure, which diminished the potential for clinical transla...
