Bionanocomposites: Differential Effects of Cellulose Nanocrystals on Protein Diblock Copolymers

We investigate the effects of mixing a colloidal suspension of tunicate-derived cellulose nanocrystals (t-CNCs) with aqueous colloidal suspensions of two protein diblock copolymers, EC and CE, which bear two different self-assembling domains (SADs) derived from elastin (E) and the coiled-coil region of cartilage oligomeric matrix protein (C). The resulting aqueous mixtures reveal improved mechanical integrity for the CE+t-CNC mixture, which...
