Multiple strategies to control the hydrophilic–hydrophobic balance of P(DMA-co-DMAEMA-co-QDMAEMA) coatings

Abstract

The regulation of hydrophilic-hydrophobic balance of polymers has an important influence not only on their aggregation behavior in aqueous solution, but also on their adhesion properties on the surface of...

Antifouling Surfaces Based on Polyzwitterion Loop Brushes

“…The successful syntheses of these copolymers were confirmed by 1 H NMR (Figures S1−S3). In particular, the resonance peak for the methene protons next to the amine (2H, −CH 2 −N(CH 3 ) 2 ) in the DMAEMA unit centered at 2.6 ppm for the precursor copolymer (Figure S2) completely disappears in the spectrum of the final product; meanwhile, a new peak emerges at 3.25 ppm (Figure S3), which is assigned to the methyl protons (6H,−N + (CH 3 ) 2 −) of ammonium in the SBMA unit, 43 indicating complete conversion of DMAEMA in the copolymer into SBMA.…”

Physicochemical properties of functionalized A200 and SBA-15 nanoparticles with enhanced amphiphilicity for Pickering emulsions

“…15 The amphiphilicity, as well as biocompatibility, environmental friendliness, non-toxicity and non-irritation of PEG polymers enable their wide use in cosmetic, papermaking, paints, rubber, plastics, and metal processing industries. 16 Inspired by mussel adhesion proteins, [17][18][19] dopamine and its derivatives can be grafted onto the surface of any inorganic or organic material by the ''grafting to'' method, 20 which utilizes the inherent adhesive properties of catechol groups. 21 Herein, a methoxy poly(ethylene glycol)-poly(dopamine methacrylamide) (mPEG-PDMA, abbreviated as mp) amphiphilic block copolymer was designed and synthesized by the atom transfer radical polymerization (ATRP) method, where PDMA and mPEG were used as the adhesion block and functional backbone, respectively.…”

An electron beam irradiation-assisted coating method for the regulation of hydrophilicity and hydrophobicity

“…The challenges of the above methods arise from the instability of these external stimuli, the manufacturing cost of the corresponding device, and the limited range of surface contact angle control. Similarly, chemical modification [20][21][22] and plasma spraying techniques 23 are employed to augment the hydrophilicity of surfaces to achieve desired surface properties. The above methods often encounter difficulties in achieving the specific contact angle requirements for a stable interface.…”
