Properties and demonstration of the mechanical stiffening of the nanocomposites under biologically relevant conditions. (a) Comparison of the tensile storage modulus (E′) of 30 wt % t-CNC-g-POEG3A/PVAc (1) and t-CNC-g-POEG2MA/PVAc (2) nanocomposite films in water at different temperatures. (b) Images of a wet 30 wt % t-CNC-g-POEG2MA/PVAc composite stiffened enough to retain the shape of a human nose upon exposure to a warm hand.
