Title:
細孔にグラフトされたポリマーを有するセラミックナノろ過膜及びその製造方法
Document Type and Number:
Japanese Patent JP7412408
Kind Code:
B2
Abstract:
The present invention relates to a method of manufacturing a nanofiltration membrane, comprising the steps of providing a support structure comprising a first mesoporous layer made of TiO2and/or ZrO2and a second porous layer adjacent to the mesoporous layer made of a material different from TiO2and/or ZrO2; grafting an anchoring group within pores of the first mesoporous layer, wherein the second layer is inert to the grafting step; covalently bonding an initiator for a surface initiated atom transfer radical polymerization reaction to the anchoring group; impregnating the support structure with a monomer and a solvent; and performing a polymerization reaction, comprising passing a catalyst through the mesoporous layer, the monomer being configured to start the polymerization reaction by grafting from the initiator in the presence of the catalyst. A nanofiltration membrane is provided as well.
