Polyaniline (PANI) with a well-ordered 3D micro array is prepared by using MEMS processes and its electrochromic properties are investigated by comparison with a 2D planar one. The 3D sample has ...

Moreover, we have demonstrated that designed arrangement of nanoparticles in 1D and 2D arrays could be achieved by prescribing specific vertices of the octahedron as nanoparticle connecting sites.
