  • Azo monomer, and azo polymer prepared by polymerization of azo monomer
    Patent number: 10173967
    Abstract: According to one embodiment of the present invention, an azo polymer forms a complex with a lithium ion and a sodium ion among alkali metal ions, but does not form a complex with a potassium ion. Therefore, the azo polymer is expected to be utilized as a material for a sensor capable of selectively detecting a specific alkali metal ion, or as a novel material capable of selectively trapping a specific alkali metal ion from a solution in which metal ions are mixed.

  • Method for wet etching of block copolymer self-assembly pattern
    Patent number: 10153173
    Abstract: The present invention relates to a process for selectively removing a block on one side using a wet etching process in connection with self-assembly block copolymer thin films that have etching-resisting properties different from each other. The present invention can form a vertical nanopore structure having a high aspect ratio, even in the case of a thick film which has a vertically oriented cylinder self-assembly structure and which has one or more periods, by overcoming the limit of the prior art, which cannot implement a vertical pore structure through wet etching.
