Gye Chung-il, Lee Chang-ho, senior researchers at LG Electroniccs and Professor Park Hyung-gyu at the Department of Mechanical and Process Engineering at ETH Zurich confirmed that ‘graphene separation membrane,’ which was made after etching pores, had higher penetrability than the existing separation membrane. The research result was published on April 18 in the Science.

First discovered in 2004, Graphene is a thin and plain material, consisting of six carbon atoms arranged in a regular manner,

Graphene is dubbed as an ideal material as it is 100 times stronger than steel, conducts electricity/ heat. It also maintains its electrical properties even after being bent.

Researchers studied how to create graphene membranes in order to secure core technology in applying graphene to water process and air purifiers.

The researchers attached two 0.2 nm-thin graphene layers to etch pores, creating graphene separation membrane. This enables selective screening of liquid and gas. This means they etched small pore on the attached two-layered material.
