Core–shell graphene oxide–polymer hollow fibers as water filters with enhanced performance and selectivity

Abstract

Extraction of proteins from blood biological fluids requires the removal of large aggregates or cells by membrane filtration. However, conventional filters, based on simple size exclusion, do not allow to...

Effect of Graphene Oxide and Nanosilica Modifications on Electrospun Core-Shell PVA–PEG–SiO2@PVA–GO Fiber Mats

“…Electrospinning, introduced and developed in the 1980s [ 1 ], remains the subject of attention for researchers as a versatile technology for producing fibers with a diverse range of diameters, morphologies, and functions. Electrospun fiber mats have found application as filters [ 2 ], membranes, substrates for tissue engineering and growth [ 3 , 4 , 5 , 6 ], wound dressings [ 7 , 8 , 9 ], and photocatalysts for water defluoridation and cleansing [ 10 , 11 ]. The properties of the fibers depend on various polymer frameworks, which differ in their biocompatibility, biodegradability, hydrophobicity, and water solubility.…”

Progress of polyethersulfone composites and their applications in biomedical engineering

“…6c). 79 The results indicated that the inner-coated PES/GO composite HFs (PES wrapped GO) had the best removal efficiency (50%) towards ciprofloxacin, followed by 20% clearance rate for the outer-coated case (GO wrapped PES). In contrast, the uncoated PES HF filters delivered insignificant filtering effects for the standard contaminants.…”

Graphene oxide-polysulfone hollow fibers membranes with synergic ultrafiltration and adsorption for enhanced drinking water treatment

“…Finally, considering a 3.5% of GO in PSU-GO HFs, the calculated release of GO after 30 min of sonication, was always lower than 0.2% (ESI, Table S8). To the best of our knowledge, this is the first case of study on release from PSU-graphene composite with a limit of quantification below the mg/L limit, typically achieved by UV-vis or TOC analyses [61].…”
