“…The DMA–MPC–PHB terpolymer solution was dissolved at a concentration of 4 mg mL −1 in a Tris-DMF buffer (20% DMF, pH = 8.5). 33 The bare substrates were immersed in the terpolymer solutions at room temperature for 24 hours in dark. Afterwards, the samples were soaked in 20 mg mL −1 sodium hydroxide (NaOH) for 10 minutes at room temperature to obtain hydroxylated surfaces.…”

“…Normal force of 100–300 nN (equivalent to a contact pressure of 34.4–49.6 MPa) was used in the tribological test, with a scanning rate of 2 Hz, 20 mm-long sliding distances, and 20 × 20 mm scanning area. 33 Deionized water served as the lubricating medium. The COF value was calculated by COF = f / N ( f represents frictional force, N refers to normal force).…”

“…However, the preparation process of these coatings is complex, and grafted polymers are prone to damage under wear, shear, or other mechanical loads. A simple method was to combine dopamine with hydrophilic macromolecules and deposit hydrophilic macromolecules on the surface of the material by the strong adhesion of dopamine. , This strategy does not require modification of the hydrophilic polymers. However, plasma treatment is also required on the surface of the substrate, and the preparation process is more complicated.…”

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

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.

Surface-independent smart antibacterial coatings with on-demand antibiotics release profiles have attracted increasing attention in medical instruments, antibiotics delivery platforms, and implanted devices. Although several approaches have been well documented, the facile preparation of antibacterial coatings onto universal substrates with high antibiotics loading efficiencies, tunable drug release profiles, and excellent antibacterial performances is still met with many challenges, especially related to the redundant coating material synthesis and selective substrate fabrication process. To resolve this issue, the authors report a facile and robust fabrication method towards smart antibacterial coating surfaces on various substrates via a one-pot integration of two types of naturally occurring building blocks, aminoglycosides and protocatechualdehyde in the presence of plant enzyme horseradish peroxidase. The simultaneous dynamic imine bonds formation and enzymatic polymerization within the system during the one-pot reaction enable the facile fabrication of diverse surface-independent smart antibacterial coatings, which can demonstrate several promising features including high drug loading and dynamic (i.e., pH-responsive) properties, tunable and on-demand antibiotics release behaviors, and efficient antibacterial activities both in vitro and in vivo. This work may offer new opportunities towards the robust and universal antibacterial coating materials by the bioinspired integration of all natural building blocks.
