Problems solved by technology

However, in this filtration membrane, the porous support is a non-woven fabric network that maintains strength and has porosity, and the asymmetric membrane is a reverse osmosis membrane that allows water to pass through but does not allow ions to pass through. The woven fabric only functions to filter particles larger than the pores included in the water, so a laminated reverse osmosis membrane is required to filter ions
[0008] Therefore, the filtration membrane disclosed in Korean Patent Publication No. 10-2012-0077266 has the problem of being thick and requiring a lot of production costs, and is limited in increasing the flow rate due to poor hydrophilicity.

Embodiment Construction

[0035] Hereinafter, specific contents for implementing the present invention will be described with reference to the drawings.

[0036] refer to figure 1 , The functional film 100 of the first embodiment of the present invention is characterized in that the above-mentioned functional film 100 is formed by accumulating nanofibers 110 and forming a nanofiber network with a plurality of pores 120, wherein the above-mentioned nanofibers are made of dopamine It is made by electrospinning the spinning solution mixed with monomer or dopamine polymer, solvent and polymer substance.

[0037] Among them, such as figure 2 As shown in the chemical formula of , dopamine (DOPAMINE, 3,4-dihydroxyphenylalanine (3,4-dihydroxyphenylalamine)) has a structure in which -NH and -OH are combined in a benzene ring.

[0038] Therefore, the functional membrane 100 according to the first embodiment of the present invention is a nanofibrous network in which nanofibers containing dopamine are accumulat...

Abstract

Provided are a functional membrane and a method of manufacturing the same, in which the functional membrane has a structure that is formed by accumulating nanofibers that are formed by electrospinning a spinning solution that is produced by mixing a dopamine monomer or polymer, a solvent and a polymer material.

Description

technical field [0001] The present invention relates to a functional membrane, and more specifically relates to a functional membrane and a preparation method thereof. The functional membrane can increase filtration efficiency, improve fouling characteristics, filter heavy metals, bacteria and viruses, and can achieve ultra-thin type. Background technique [0002] Currently, due to rapid industrialization and population increase, water shortages are occurring in every corner of the earth. [0003] More than 97% of the water existing on the earth is seawater or glaciers that cannot be directly used, making it difficult to use it for industry and drinking water. [0004] Many studies have been conducted to solve the above-mentioned water shortage phenomenon, and desalination research for desalination of seawater is actively carried out, and water that has been used for industrial and domestic use is continuously reused or groundwater and water on the surface of the ground are...
