“…Freeman and his co-workers performed lots of work regarding the fabrication of anti-fouling surfaces by grafting PEG-NH 2 onto PDA-modified membranes with different separation scales, and they also investigated the effects of PDA deposition conditions on the performance of the membranes [124][125][126]. Briefly, they found that the protein adhesion decreased with the increase in the grafting density of PEG, and the change of pure water flux was largely dependent on the pore size.…”

“…When a polyethersulfone (PES) membrane (PES-20), with MWCO of 20 kDa, was coated for 5 min and 30 min, the pore size became equivalent to that of PES-10 and PES-5, respectively. When the membranes with a similar pore size were tested with wastewater containing oil/water emulsion in a constant permeate flux crossflow system, the PDA-coated membranes demonstrated lower transmembrane pressure than the unmodified ones, indicating the enhanced antifouling properties by PDA coating [47,48]. …”

Membrane technology has emerged as an attractive approach for water purification, while mitigation of fouling is key to lower membrane operating costs. This article reviews various materials with antifouling properties that can be coated or grafted onto the membrane surface to improve the antifouling properties of the membranes and thus, retain high water permeance. These materials can be separated into three categories, hydrophilic materials, such as poly(ethylene glycol), polydopamine and zwitterions, hydrophobic materials, such as fluoropolymers, and amphiphilic materials. The states of water in these materials and the mechanisms for the antifouling properties are discussed. The corresponding approaches to coat or graft these materials on the membrane surface are reviewed, and the materials with promising performance are highlighted.

“…Freeman and co‐workers demonstrated the structural model of polydopamine and systematically investigated the deposition conditions to confer membranes with various functions . Faure et al confirmed that the catechols could form covalent or strong noncovalent interactions, such as p‐electron, hydrogen‐bonding, and other interactions with organic substrates .…”

Herein, a facile one‐step surface modification technique of coating functional biopolymer conjugated mussel‐inspired catechol (CA) onto substrate is applied to confer polyethersulfone (PES) membranes with remarkable blood compatibility, antifouling property, and antibacterial property, respectively. CA conjugated poly(2‐acrylamido‐2‐methylpropanesulfonic acid) (PAMPS), poly(sulfobetaine methacrylate) (PSBMA), and poly(methacryloxyethyltrimethyl ammonium chloride) are synthesized via free radical polymerization in the presence of CA, and simultaneously coated onto PES membrane surface. The surface chemical compositions, surface zeta‐potential convince the successful preparation of the modified PES membranes. PAMPS‐coated membrane exhibits excellent blood compatibility, especially anticoagulation property; PSBMA‐coated membrane displays excellent antifouling property and blood compatibility; meanwhile, PDMC‐coated membrane shows robust bactericidal property. In general, this work demonstrates that the mussel‐inspired surface modification protocol provides a facile and versitile method to confer the substrate with excellent blood compatibility, antifouling property, and antibacterial property, respectively, which has great potential for multibiomedical applications, such as blood purification, hemodialysis, and organ implantation.
