We designed a kind of smart bioinspired fiber using the N-isopropylacrylamide
(NIPAAm) polymer, with roughness and curvature
features similar to those of wetted spider silk. The motion of tiny
water droplets can be manipulated reversibly in directions by the
effective cooperation of multi-gradients such as roughness, curvature
and temperature-responsive wettability.
