2020年10月5日 · In this review, we focus on three aspects of functional hydrogel coatings: (i) applications and functions enabled by hydrogel coatings, (ii) methods of coating various substrates with different functional hydrogels with tough adhesion, and (iii) tests to evaluate the adhesion between functional hydrogel coatings and substrates.

2024年2月1日 · Hydrogel coatings of catheters have attracted extensive attention in the field of medical devices due to its hydrophilicity and softness, while scarcities of Janus adhesion, adaptive antibacterial property, and real-time disease monitoring restricted their clinical translational applications.

2020年10月5日 · In this review, we focus on three aspects of functional hydrogel coatings: (i) applications and functions enabled by hydrogel coatings, (ii) methods of coating various substrates with different functional hydrogels with tough adhesion, and (iii) tests to evaluate the adhesion between functional hydrogel coatings and substrates.

2024年9月23日 · Biomimetic hydrogel lubrication coatings with high wettability and low friction show great promise in tissue engineering, wound dressing, drug delivery, and intelligent sensing. Inspired by the hierarchical structure of natural cartilage, a layered hydrogel coating was constructed to functionalize rigid polyetheretherketone (PEEK).

2022年9月12日 · Here, we report a poly (carboxybetaine) microgel reinforced poly (sulfobetaine) (pCBM/pSB) pure zwitterionic hydrogel with excellent mechanical robustness and anti-swelling properties. The...

2021年9月20日 · Hydrogels with three-dimensional crosslinked hydrophilic networks, tunable mechanical property and large drug-loading capacity are desirable coating materials, which can kill bacteria and/or prevent bacterial adhesion on the surface, inhibiting biofilm formation. Herein, we review recent developments of hydrogels as anti-infective coatings.

2021年6月2日 · In summary, we developed a simple yet effective method, named renatured hydrogel painting (RHP), to prepare robust hydrogel coatings on various solid substrates. This hydrogel painting method involves the coating of adhesive and xerogel particles, followed by rehydration of xerogel into hydrogel.

2020年11月1日 · Coating substrates with antibacterial hydrogel layers has been recognized as an effective strategy to combat bacterial colonization. To prevent possible delamination of hydrogel coatings from substrates, it is crucial to attach hydrogel layers …

2024年9月13日 · In summary, the current Research Topic reports the recent significant advances in hydrogel surface/coatings for smart drug delivery and medical devices. The design and development of functional hydrogels will provide new opportunities for smart drug delivery towards clinical application and the development of medical devices.

2024年11月9日 · To investigate this further, we applied our double‐hydrophobic‐coating method to a Ca‐alginate/PAAm double‐network hydrogel, which is a widely used tough and stretchable hydrogel.4, 32 Although the hydrogel contained ≈90 wt% water, the coating was capable of maintaining the water content in air for a prolonged period.
