| Abstract: | Contrary to expectation, we demonstrate that spider dragline silk spun experimentally under water displays greater stiffness and higher resilience compared to silk spun "naturally" into air. We suggest that this consequence of extended wet-spinning is due to increased molecular orientation resulting from extension of the mobile phase. |
