In this work, innovative hollow fiber membranes and flat membranes with unique structures were developed to prevent organic fouling and biofouling. The PVDF hollow fiber membranes with uneven structures newly prepared in this work showed low organic fouling property. Nano-patterned flat membranes (Pillar, Hole and Line) were prepared by template method. Effect of surface pattern structures on the biofilm formation of Pseudomonas putida (P. putida) was investigated. The membrane surface with pillar structure was useful to decrease the biofilm formation.
