LIQUID FILTERING STRUCTURE

摘要

A liquid filtering structure having high filtering efficiency, excellent transparency, and excellent durability can be provided. The liquid filtering structure includes a filtering layer, wherein the filtering layer includes a nanopore structure unit including a plurality of nanopores and a functional group-containing compound including functional groups at one end, and has selectivity with respect to liquid molecules to be filtered, for example, water molecules, and effectively filter liquid, particularly water by preventing ions or compounds from being passed.

1. A liquid filtering structure comprising a filtering layer, the filtering layer comprising:
a nanopore structure unit comprising a plurality of nanopores; and a functional group-containing compound comprising functional groups at one end, wherein the nanopores penetrate the filtering layer in a thickness direction of the filtering layer and have an average diameter of 0.2 nm to 20 nm, and the functional group-containing compound is chemically combined with internal walls of the nanopores.
