Antifouling ability of polyethylene glycol of different molecular weights grafted onto polyester surfaces by cold plasma

New hybrid materials based on poly(ethyleneoxide)-grafted polysilazane by hydrosilylation and their anti-fouling activities

“…The anti-fouling activities of PSZ-PEO showed an increase in the sequence PEO750 < PEO2000 < PEO350. This result may seem to disagree with several previous studies showing that a PEO2000 chain is most effective against bacterial adhesion [12,26–27]. However, all PSZ-PEO350 coatings have a PEO grafting density that is higher than that of PSZ-PEO750 and PSZ-PEO2000 at the same Si–H/allyl ratio (see Table 1).…”

“…These include the hydrophilicity [7], the mobility, the large exclusion volume in water and the effect of steric repulsion [8–11]. The effect of the molecular weight and the grafting density of PEO on the anti-fouling capacity has been widely studied [12–14]. …”

“…These include the covalent grafting [15–16], the chemical adsorption [17], the formation of self-assembled monolayers [18–19], plasma treatment [12,20] or the use of supercritical CO 2 [21–22]. Kingshott et al have demonstrated that the grafting of PEO onto the substrates by covalent bonding is necessary for an anti-fouling activity [23].…”

Role of molecular properties of ulvans on their ability to elaborate antiadhesive surfaces

“…The evolution curve of the antiadhesive activity of modified surfaces according to the polysaccharide molecular weight followed a parabolic behavior with a maximum of inhibition with P2. This result is in accordance with Dong et al who investigated the antifouling ability of polyethylene glycols (PEGs) of different molecular weights grafted onto polyester surfaces. These authors reported an optimum molecular weight around Mw = 2000 g mol −1 and no further reduction of biofilm formation when the molecular weight was increased to 4600 g mol −1 .…”

Preparation of hairy particles by grafting PEG onto the poly(styrene‐co‐maleic anhydride) surface and PEG effect on SiO2 nanoparticles adsorption

“…There are several methods to graft PEG or its derivatives, such as cold plasma,25 esterification with acid anhydride group26 or with carboxyl groups,27 photopolymerization of PEG monoacrylate on PMAA films,28, 29 or by living polymerization 30, 31. To prepare hairy‐like polymer particles, it is effective to copolymerize vinyl monomers with maleic anhydride (MA) to gain prefunctionalization on the particles' surface.…”
