“…However, when the grafting time is greater than 6 h, the growth rate slows down gradually. Similar results were observed in several SI-ATRP studies [27,28]. Theoretically, a linear relationship between DG and polymerization time would be produced by a constant radical concentration using an excess of monomer in the ATRP reaction.…”

“…As demonstrated in Figure and Table , protein fouling on PSf/SiO 2 membrane is most reversible, especially due to the hydrophilic groups of the silica that first interacts with water molecules to form hydrated layer on the membrane surface and then makes BSA molecules easy to be removed by hydraulic cleaning . An irreversible fouling was occurred owing to the physical entrapment of the proteins in the SiO 2 ‐templated pores of PSf/WSiO 2 .…”

In the present paper, hierarchically structured ultrafiltration polysulfone (PSf) membrane was prepared to explore the effect of addition and subsequent removal of SiO 2 nano-particles on the membrane morphology, hydrophilicity, and separation properties. The PSf based membranes namely PSf, PSf/SiO 2 and PSf/WSiO 2 (i.e. SiO 2 nano-particles was acid-washed and removed from PSf/SiO 2 ), were synthesized and characterized by different characterization methods. Pure water flux through the membranes was determined using a filtration unit operating at a continuous dead-end flow mode. The modification enhanced the morphology, hydrophobicity, porosity and transport properties of the modified membranes, although the molecular weight cut-off (MWCO) of the membranes was not changed considerably. In comparison, PSf/WSiO 2 membrane exhibited excellent pure water flux (about 4.5 times the flux of PSf, and 17 times the flux of PSf/SiO 2 ), although antifouling property of PSf/SiO 2 in separation of bovine serum albumin (BSA) was better than that of PSf and PSf/WSiO 2 membranes. The results suggested that the addition/removal of sacrificial solid fillers within/from a membrane matrix may provide a promising strategy to enhance PSf membrane transport property.

“…Graft density is determined by the surface density of initiator which is not sterically limited since the initiator is a small molecule 85. PVP can be chemically grafted on material surfaces by conventional free radical polymerization, RAFT polymerization,90 atom transfer radical polymerization (ATRP),91–95 and other polymerization techniques.…”

Poly(N-vinylpyrrolidone) (PVP), an important water soluble synthetic polymer, has many desirable properties including low toxicity, chemical stability, and good biocompatibility. Since PVP is hemocompatible and physiologically inactive, it has been used as a blood plasma substitute. Surface modification with PVP has been investigated extensively over the past few years as a means of preventing nonspecific protein adsorption. PVP may therefore be seen as a promising antifouling surface modifier comparable to poly(ethylene glycol) (PEG). In this review, various approaches for the design and preparation of PVP-modified surfaces are summarized and potential biomedical applications of these PVP-modified materials are indicated. Finally, some perspectives on future research on PVP for surface modification are discussed.
