  • Nano-porous thin film, methods of fabricating thereof and triboelectric generator using the same
    Patent number: 10622919
    Abstract: The present invention relates to a nano-porous thin film comprising a supramolecular structure having a skeleton, a first compound block and a second compound block including a functional group is self-assembled to form a spherical micelle, the first compound block constitutes a core of the spherical micelle, and the second compound block constitutes a shell of the spherical micelle, the first compound block is removed from the spherical micelle while the second compound is remaining so that the remaining second compound provide the skeleton of the supramolecular structure, the supramolecular structure comprises pores formed therein, and metal ions selectively bonded to the functional group.
