Abstract
Carboxylated graphene oxide modified PLA membrane via mussel-inspired method exhibited excellent hemocompatibility and dialysis performance.
Highlights
Biodegradable polymers have attracted much attention due to environment and sustainability issues.[1]
The chemical compositions and morphology of graphene oxide (GO)–COOH were analysed by FTIR spectroscopy (Fig. S1†) and AFM (Fig. S2†)
The results indicated the GO–COOH nanosheets successfully prepared
Summary
Biodegradable polymers have attracted much attention due to environment and sustainability issues.[1]. Chang et al gra ed zwitterionic poly(sulfobetaine methacrylate) (PSBMA) onto PVDF membrane and PP brous membrane via plasma-induced surface copolymerization to improve the materials' blood compatibility.[8,9] Zhu et al gra ed PSBMA to PLA membrane surface by atom transfer radical polymerization (ATRP) to improve the fouling resistance and hemocompatibility.[2] Xiong et al improved the blood compatibility of PLA membrane by bonding heparin via surface cross-linking and glycidyl ether reaction.[10] Li et al immobilized natural hirudin on PLA membrane to develop a hemocompatible PLA membrane through the hydrogen bonding interaction.[11] plasma treatment and ATRP are somewhat complex and may be not suitable for large-scale surface modi cation.[12]
