“…The flux loss caused by irreversible protein fouling ( R ir ) decreased from 36.6% to 29.9% and 24.4% in the first cycle and decreased from 26.5% to 16.1% and 11.0% in the second cycle, corresponding to PAN membranes and PAN‐SiO 2 and PAN‐TiO 2 MMMs, respectively. Many researchers have found that hydration layers can be generated on the top surfaces of hydrophilic membranes, which resist the adsorption and deposition of proteins. In our works, due to the migration of most of the TiO 2 generated in situ to the phase separation interfaces, the hydrophilicity of PAN‐TiO 2 MMMs had the greatest improvements.…”

Mixed matrix membrane (MMM) structures and performances are greatly affected by the distribution of nanoparticles in the polymeric matrix. Until now, there has been little research on the effects of nanoparticle distribution states on polyacrylonitrile (PAN)‐based MMM structures and performances. In this paper, different intermolecular interactions between nanoparticles and PAN molecules were generated by in situ fabricated amino‐functionalized SiO2 and TiO2 nanoparticles to create absolutely different distribution states of nanoparticles in a PAN matrix. The results indicated that, due to the strong interactions between amino and cyano groups, SiO2 is distributed in the PAN membranes homogeneously, while most of the TiO2 migrates to the membrane's top surfaces or the walls of pores or even escape from the membranes during the nonsolvent index phase separation (NIPS) process. PAN‐TiO2 MMMs have more hydrophilic top surfaces, higher porosity, larger mean pore size, and stronger antifouling performances than pure PAN and PAN‐SiO2 membranes. The PAN‐TiO2 MMMs have an ultrahigh water flux of 1204.6 L/(m2 h), which is more than 44 times that of PAN membranes. And the good pore structures and hydrophilicity of the membranes derived from special interactions between in situ TiO2 nanoparticles and PAN molecules can give high‐performance PAN‐based ultrafiltration membranes a bright future. © 2019 Wiley Periodicals, Inc.

Abstract. In this study, cellulose acetate/polyethylene glycol (CA/PEG) membrane with composition 80/20 was prepared by phase inversion method. Titanium dioxide with different number has been added by using surface coating. Hydrophilicity, morphology, flux permeate and salt rejection of membranes has been studied. The hydrophilicity is determined by FourierTransformed Infra-Red (FTIR) spectra and contact angle analysis. Surface and fractured morphology are identified by using Scanning Electron Microscopy (SEM). The experiment results show that hydrophilicity of CA/PEG membrane increases with the addition and the increasing of TiO2 contents. However, with further increasing of TiO2, hydrophilicity of CPT membrane decreases. The optimum membrane is CA/PEG/TiO2 80/20/1,25 g/L solvent (CPT 3) with flux permeate of 111,82 L.m-2h-1 and salt rejection of 48,30%.

Surface Modification of Polysulfone Membranes Using Poly(Acrylic Acid)‐Decorated Alumina Nanoparticles

Alumina nanoparticles were decorated with poly(acrylic acid) (PAA) as a hydrophilic polymer by thermal polymerization of acrylic acid in the presence of alumina nanoparticles. The obtained PAA-decorated alumina (PAA-d-Al) nanoparticles were embedded in the polysulfone membrane matrix via nanofiller dispersion in the casting solution. The prepared membranes were characterized by porosity and water contact angle measurements, scanning electron and atomic force microscopy, and fouling tests using whey proteins. The presence of nanoparticles had significant effects on the membrane hydrophilicity and surface softness, resulting in fouling mitigation and flux recovery enhancement compared with the virgin polysulfone membrane. Moreover, the prepared membrane embedded with 0.25 wt % of PAA-d-Al nanofillers showed a remarkable durability and reusability during the filtration tests.
