Document Type and Number:
WIPO Patent Application WO/2012/173417
Kind Code:
A2
Abstract:
The present invention relates to a reverse-osmosis membrane having an ultra-hydrophilic protective layer, comprising: a complex metal oxide containing Si and one or more metal elements selected from the group consisting of Ti (IV), Zr (IV), Sn (IV), and Al (III); and an organic compound which contains an ultra-hydrophilic group and which is physically or chemically linked to the Ti (IV), Zr (IV), Sn (IV), or Al (III) of the complex metal oxide. The present invention also relates to a method for producing the reverse-osmosis membrane. According to the present invention, the reverse-osmosis membrane can be produced such that the performance of the reverse-osmosis membrane in terms of durability, chlorine resistance, and fouling resistance is improved through a single coating.
