Creating functional film coatings for the specific use of them is highly demanded in materials engineering. In our lab, we have studied many years in the development of functional coatings created by polyelectrolyte multilayer film by layer-by-layer method. We have prepared polyelectrolyte coatings on filtration membrane and characterized the properties of the membrane surface with contact angle, water filtration and anti-fouling test. We modified the surface to be hydrophilic and as the results, increasing surface wettability and anti-fouling properties were achieved. Also we prepared nano porous coating through microphase separation of polymer blend. We characterized the properties of the membrane surface with AFM, contact angle, anti-fouling test, water flux test, and rejection test using nano particle solution. We expect these coated membranes to show improved functionality as a membrane and have a great potential to be used in environmental fields.
