Surface-initiated atom transfer radical polymerization (SI-ATRP) is a powerful method to uniformly modify the surface of reverse-osmosis (RO) membranes with functional polymers and prevent biofouling. However, immobilization of the initiator, an essential step of SI-ATRP, is difficult to perform directly on commercial polyamide RO membranes. This study describes an effective pretreatment method to immobilize ATRP initiators on the surface of polyamide RO membranes and the effect of the polymer chain length on the biofouling behavior. Firstly, RO membrane surfaces were aminated with 3-aminopropyltrimethoxysilane (APTES). Then, alpha-bromoisobutyryl bromide (BIBB), an acyl halide-type ATRP initiator, was reacted with the APTES layer. A zwitterionic polymer, poly[(2-methacryloyloxy)ethyl]dimethyl[3-sulfopropyl]ammonium hydroxide (pMEDSAH), was then grafted on the membrane surface via SI-ATRP. The APTES treatment effectively improved the amount of BIBB immobilized on the membrane surface, maintaining the water permeability and salt rejection properties of the RO membrane. pMEDSAH grafting enhanced the surface hydrophilicity and changed the surface to a smoother and denser morphology. Regarding the biofouling behavior, static bacterial adhesion on the membrane surface was prevented by increasing the ATRP polymerization time. In cross-flow bacterial filtration tests, the membranes grafted with pMEDSAH at polymerization times of over 1 h presented no permeability decline and little biofilm coverage.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 16858-01-8 is helpful to your research. Related Products of 16858-01-8
