제목 Enhancement of anti-biofouling properties of polypropylene membrane via bioinspired CaCO3 coating and hydrophilic graft polymerization
초록 Commercial membranes are generally manufactured by using hydrophobic polymer materials, but hydrophilic surface membranes are essential for polymer-based water purification membranes. The surface modification of micropolypropylene membrane (MPPM) was performed by the sequential photoinduced graft polymerization of acrylic acid (AA) and the bioinspired CaCO3 coating technique. The structural and morphological changes of membrane surface were characterized by Fourier transform-infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The water contact angle of the modified membrane through grafting was significantly decreased (i.e., decreased to <10° after mineral coating) with the increase of grafting degree (GD). In addition, the analysis of ultraviolet visible light spectroscopy showed a clear difference in bovine serum albumin (BSA) adhesion compared to unmodified membrane.
