Abstract
A hybrid type filtration structure for filtering liquid includes a first active layer, a porous supporting layer and a permeable layer. The first active layer has a first nano pore inner wall of which a function group included compound is combined with. The porous supporting layer has a plurality of pores and is disposed under the first active layer. The permeable layer is disposed under the porous supporting layer. The porous supporting layer includes a plurality of lipid bilayers having membrane protein inside of the pore, a molecule of water selectively passes through the membrane protein. The first nano pore passes through the first active layer vertically. The first nano pore and the pore are connected with each other through which liquid flows.
