“…In order to further confirm the existence of PAA in the coating and to understand the composition of the coating more clearly, XPS analysis was performed on the surface of the samples (Figure C–E). The PDMS surface deposited by PDA has obvious peaks at 284.6, 285.5, 286.4, and 287.3 eV, which are attributed to C–H, C–N, C–O, and CO bonds, respectively . These bonds correspond to the amine group, catechol functional group, and quinone group in PDA.…”

Existing medical materials (such as silicone rubber, glass slides, etc.) fail to meet the functional requirements of biosensing, cell culture, and drug delivery due to their poor wettability. The preparation of polyelectrolyte coatings with excellent wettability and protein adsorption helps broaden the application of medical materials. Poly(acrylic acid) (PAA) is a common polyelectrolyte with stronger protein adsorption, but the existing methods for obtaining PAA coating have certain shortcomings to limit their industrial applications. In this study, dopamine (DA) was used to polymerize and co-deposit acrylic acid (AA) in weak acid solution to functionalize the surface of materials, and the effects of different mass ratios of DA/AA on the wettability and protein adsorption of the coating were deeply investigated. The results demonstrate that PDA/PAA coating is successfully prepared on the surface of four substrates and greatly reduces the water contact angle of these surfaces. Moreover, these coatings show excellent protein adsorption, and the amount of adsorbed protein on the coated QCM chip is increased by 57.74% than the uncoated QCM chip. In addition, the coating has a certain pH responsiveness, and its wettability and protein adsorption are closely related to the pH of the solution. The preparation strategy proposed is simple and substrate-independent, which provides valuable insights into the application of the one-step polymerization and co-deposition strategy under weak acid conditions.

“…These are the typical infrared absorption peaks of silicone rubber. The spectrum of the PHEMA coating shows a peak at 3380 cm –1 , attributed to its OH group, and the peaks at 1653, 1158, and 1717 cm –1 are attributed to CO groups . However, the original PDMS surface does not have these groups, indicating that PHEMA successfully polymerized on the PDMS surface.…”

“…The C 1s spectrum near 285 eV of the PDMS surface was compared before and after PHEMA coating. The uncoated PDMS sample only has one peak at 284.8 eV, while the surface with the PHEMA coating displays peaks at 284.8, 285.6, 286.8, 288.2, and 289.1 eV attributed to CH, C–N, C–O, CONH, and OCO, respectively . Among these groups, C–N only exists in the chemical structure of MBA; C–O and OCO are present in the molecular structure of HEMA, and CONH exists in MBA and PASP.…”

Fabrication of a Hydrophilic Low-Friction Poly(hydroxyethyl methacrylate) Coating on Silicon Rubber

et al. 2021

Silicon rubber has been widely used in the biomedical field due to its excellent mechanical properties and physiological inertia. However, the hydrophobic properties of silicon rubber surfaces limit their further application. Therefore, constructing a silicon rubber coating with hydrophilic and low-friction surface properties would be highly significant. Existing methods to achieve such coatings, including grafting polymer brushes and the deposition of hydrophilic materials, suffer from several deficiencies such as complicated coating processes and insufficient coating firmness. In this paper, we report a hydrophilic polymer poly(hydroxyethyl methacrylate) (PHEMA) coating that can easily coat the surface of silicon rubber to provide low-friction performance. Sample silicon rubber was treated with benzophenone and hydroxyethyl methacrylate monomer solution in turn. The as-prepared coating was characterized by infrared spectroscopy, X-ray photoelectron spectroscopy, white light interference, and MFT-5000 wear test. The results indicated that the PHEMA coating had excellent hydrophilic properties (with a low contact angle of 9.39°) compared to uncoated silicon rubber. As the concentration of glycerol in the monomer solution was increased, the thickness and surface roughness of the as-prepared coating gradually decreased. The coating was firmly adsorbed on the substrate, and it had a zero-class bonding strength. In addition, the as-prepared coating demonstrated good friction-reduced properties, with the coefficient of friction being reduced by 98.0% compared with the uncoated silicon rubber in simulated blood. In summary, a hydrophilic and low-friction coating was successfully prepared using a simple method, and the results reported herein provide valuable insight into the surface design of similar soft materials.

“…L'adesione batterica e la sua proliferazione su una superficie dipende da molti fattori quali, la carica e la morfologia della superficie, il pH, la forza ionica ma primariamente dalle caratteristiche di bagnabilità del materiale adottato. 1,2 Superfici idrofile tendono a sfavorire l'adesione e la crescita batterica anche a seguito della presenza di strati strutturati di acqua chemi-e fisisorbita che contrastano il contatto diretto tra i batteri e la superficie. D'altra parte, in situazioni cliniche diverse è opportuno prevenire fenomeni di adesione di proteine e cellule, come nel caso, ad esempio, di stent vascolari o barriere peritoneali; la superficie del materiale deve presentare, in questo caso, caratteristiche di elevata idrofobicità e bassissima adesione.…”

The wettability of solid surfaces is the result of the balance between adhesive and cohesive forces. When adhesive forces at the solid/liquid interface prevail over the cohesive forces in the liquid, the drops will spread over the solid leading to a good wetting as in the case of water over an hydrophilic surface. When instead the adhesive forces are weak, the liquid will not wet the surface remaining in droplets, as water on a polymer. Natural materials exhibit tailored wetting behavior: for instance, certain leaves and insects present superhydrophobic properties. By mimicking what nature creates in an exemplary way, the wetting properties of systems can be tailored experimentally to obtain materials with great applicative impact. The possible applications of such phenomena are very numerous and span from biomaterials to antistain materials, from antifog surfaces to systems for the protection of cultural heritage.
