By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Proteins have been published. According to news originating from Fuzhou, People's Republic of China, by NewsRx correspondents, research stated, "A novel hydrophilic nanocomposite additive (TiO2-g-PNIPAAm) was synthesized by the surface modification of titanium dioxide (TiO2) with N-isopropylacrylamide (NIPAAm) via 'graft-from' technique. And the nanocomposite membrane of poly(vinylidene fluoride) (PVDF)/TiO2-g-PNIPAAm was fabricated by wet phase inversion."
Our news journalists obtained a quote from the research from Fujian Medical University, "The graft degree was obtained by thermo-gravimetric analysis (TGA). Fourier transform infrared attenuated reflection spectroscopy (FTIR-ATR) and X-ray photoelectronic spectroscopy (XPS) characterization results suggested that TiO2-g-PNIPAAm nanoparticles segregated on membrane surface during the phase separation process. Scanning electron microscopy (SEM) was conducted to investigate the surface and cross-section of the modified membranes. The water contact angle measurements confirmed that TiO2-g-PNIPAAm nanoparticles endowed PVDF membranes better hydrophlilicity and thermo-responsive properties compared with those of the pristine PVDF membrane. The water contact angle decreased from 92.8A degrees of the PVDF membrane to 61.2A degrees of the nanocompostie membrane. Bovine serum albumin (BSA) static and dynamic adsorption experiments suggested that excellent antifouling properties of membranes was acquired after adding TiO2-g-PNIPAAm."
According to the news editors, the research concluded: "The maximum BSA adsorption at 40 A degrees C was about 3 times than that at 23 A degrees C. The permeation experiments indicated the water flux recover ratio and BSA rejection ratio were improved at different temperatures."
