“…Highly hydrophilic surfaces with zero net charge have been reported to resist the biofouling of proteins and bacteria, − which in turn results in reduced thrombus formation and foreign-body reactions. , To achieve ultralow fouling surfaces, hydrophilic polymer coatings, such as polyethylene glycol − and zwitterionic polymers, , have been extensively explored. Concerning long-term applications in vivo, it is essential that these coatings are stable under the physiological environment.…”

Polymer grafting has been a powerful tool in the surface modification of biomaterials. Traditional solventbased grafting, however, often requires laborious procedures taken under harsh conditions, which seriously hinders its practical applications. Here, we report a facile solvent-free graft-from method that is able to achieve a superior surface functionality as compared to most reported results from traditional solvent-based grafting. The grafting was proceeded by conformally coating a cross-linked polyvinylpyrrolidone (PVP) prime layer in the vacuum, immediately followed by in situ grafting of PVP homopolymer chains from the propagating sites on the coating surface. The resultant coating exhibited enriched surface pyrrolidone content compared to the single-layer cross-linked counterpart and a water contact angle of 22°, lower than most reported PVP-grafted surfaces. Medical catheters grafted with PVP achieved a more than 99.9% bacterial antifouling enhancement compared to the pristine catheter, and significantly improved biocompatibility during a 4 week in vivo test in mice. The achieved surface functionality is attributed to the synergistic effect from the functional groups distributed both on the grafted chains and on the cross-linked primer. The effectiveness and simplicity of the vapor grafting method thus suggest a promising surface modification route for biomaterials and beyond.

“…Acrylic polymer resin is based on methyl methacrylate (MMA), ethyl acrylate (EA), polyethylene glycol methacrylate (PEGMA), ethyl hexacrylate (EHA), trimethyl silylmethacrylate (TMSA) in propylene glycol monomethyl ether (PGM) and xylene solvent mixture (1:5) using azobis isobutyronitrile (AIBN) as an initiator and was synthesized according to our previous reports [ 44 , 45 ]. The synthesis was carried in a four-neck flask equipped with a condenser, thermometer, dropping funnel and stirrer at 95 °C at a mixing rate of 200 rpm for a reaction time totaling 4 h.…”

Metal-organic frameworks (MOFs), a class of crystalline, porous, 3D materials synthesized by the linking of metal nodes and organic linkers are rapidly emerging as attractive materials in gas storage, electrodes in batteries, super-capacitors, sensors, water treatment, and medicine etc. However the utility of MOFs in coatings, especially in marine coatings, has not been thoroughly investigated. In this manuscript we report the first study on silver MOF (Ag-MOF) functionalized acrylic polymers for marine coatings. A simple and rapid microwave technique was used to synthesize a two-dimensional platelet structured Ag-MOF. Field tests on the MOF reinforced marine coatings exhibited an antifouling performance, which can be attributed to the inhibition of marine organisms to settle as evidenced by the anti-bacterial activity of Ag-MOFs. Our results indicate that MOF based coatings are highly promising candidates for marine coatings.

“…In extreme environments, such as icing, marine fouling, and continuous wetting conditions, where a robust, sustainable coating is a priority, long-term retention of properties is essential. Through the use of amphiphilic polymer coatings, several groups have demonstrated success in the field of antibiofouling or reducing protein adhesion. − Recently, Hwang and co-workers synthesized and investigated the protein adsorption of random, amphiphilic copolymer films composed of polystyrene (PS), poly(ethylene glycol) methacrylate (PEGMA), and poly(hydroxyethyl) methacrylate (PHEMA), and demonstrated that polymers containing EGMA and HEMA exhibited enhanced antibiofouling properties over those composed of PS .

Linear and hyperbranched poly(ethylene glycol)-cross-linked amphiphilic fluoropolymer networks comprised of different liquid crystalline comonomers were developed and evaluated as functional coatings in extreme weather-challenging conditions. Through variation of the liquid-crystalline comonomer and hydrophilic:hydrophobic component ratios, several series of coatings were synthesized and underwent a variety of analyses including differential scanning calorimetry, water contact angle measurements and solution stability studies in aqueous media. These materials maintained an unprecedented reduction in the free water melting transition (T) temperature across the hyperbranched and linear versions. The coatings synthesized from hyperbranched fluoropolymers preserved the liquid crystalline character of the mesogenic components, as seen by polarized optical microscopy, and demonstrated stability in saltwater aqueous environments and in cold weather conditions.
