Antifouling and antibacterial improvement of surface-functionalized poly(vinylidene fluoride) membrane prepared via dihydroxyphenylalanine-initiated atom transfer radical graft polymerizations

Fabrication of nonfouling, bactericidal, and bacteria corpse release multifunctional surface through surface-initiated RAFT polymerization

“…As reported in the process of non-selective protein adsorption on material surface, the hydrophobic interactions played an important role. 47 The effective reduction of BSA adsorption could be due to the presence of MPC in the brush coating. The high hydrophilic property of MPC groups with net neutral charges on the surface could be due to protein resistance.…”

Composition and properties of porous blend membranes containing tertiary amine based amphiphilic copolymers with different sequence structures

“…Some novel and valuable properties including hydrophilicity [5,19,20,22,26], temperature [19,26], pH [19][20][21]26], ionic strength [19,22] stimuli-responsive behaviors, drugs adsorption ability [35], anions [36,37] adsorption properties, will be endowed to the pristine matrixes, when using PDMAEMA as modifiers. Furthermore, with some simple chemical modification, the PDMAEMA containing membranes can even exhibit the antibacterial properties after having been quaternized [38] and fouling-resistance after zwitterionicalization [5]. The above discussion indicates that it is valuable to explore a proper method to prepare tertiary amine containing membranes.…”

Preparation of photo-catalytic copolymer grafted asymmetric membranes (N-TiO2-PMAA-g-PVDF/PAN) and their application on the degradation of bentazon in water

“…In the spectrum of PMAA-g-PVDF the peaks located at 1270 and 1000 cm −1 are ascribed to the stretching vibrations of -C-O of the -COOH group and these peaks indicate the successful grafting of PMAA to PVDF. The medium peak at 1139 cm −1 is ascribed to the C-O-C stretching vibrations consistent with the group formed with the graft reaction [25,27,28]. 1 H and 13 C spectra were acquired to elucidate the structure of PMAA-g-PVDF and also to confirm successful grafting of PMAA onto PVDF polymer chains.…”
