Diverse actuation by different LCST phase transitions. (a) The half-to-half structure consists of two different f-PNIPAMs which have low LCST (48.0 °C) and high LCST (60.8 °C). (b) Analysis of curvature change in (a) with increasing temperature. (c) Inverted half-to-half structure consisting of two different f-PNIPAMs with the opposite orientation in each half. One side has low LCST (48.0 °C) and the other side has high LCST (60.8 °C) (d) Analysis of curvature change in (c) with increasing temperature. (e) Structure of layer-on-layer and (f) its curvature analysis.
