By controlling the 2D programmed structures, 3D objects can reversibly change their shapes and properties. These 2D structures were first programmed to break their symmetry for structure transformation. Scroll photonic actuators had been first demonstrated by bending the traditional cantilever structure. Both left- and righthanded scrolls and helices with various colours can be achieved by changing the polarity of solvents. Different types of 3D actuators, such as cube, pyramid and phlat ball, were also demonstrated via the folding mechanism. The reversible 3D photonic actuators transformed from the programmed 2D structures via the bending, twisting and folding mechanisms. This work was mainly supported by Converging Research Center Program (2013K001428), and Human Resource Training Project for Regional Innovation funded by the Ministry of Education, Science, and Technology of Korea. |
