A Self-Lubricating PEEK Composite Enhanced by Microcapsules via Friction-Triggered Hydrogel Layer Formation.

Bioinspired polymer-incorporating self-lubricating and antifouling hydrogels.

Healthy articular cartilage exhibits a very low coefficient of friction (CoF ≈ 0.002-0.02) due to hydration lubrication at the slip plane, involving phospholipids bound to macromolecules in the cartilage matrix. Hydrogels that mimic this hydrated phosphorylcholine layer could replicate cartilage lubrication for biomedi...

Finding of Activation Energy and Self-Healing Mechanism of Sustainable Porous Ceramic Microcapsule Encapsulated Polydimethylsiloxane Elastomeric Composite

In situ polymerised KH570-OH-BNNS/PAS composite emulsion achieves superior lubricity and load-bearing capacity.

Conventional emulsion lubricants suffer from issues such as oil film rupture under high loads, poor lubrication stability and insufficient load-carrying capacity. To address these issues, this study developed an acrylic polymer emulsion (PAS) with a simple composition and KH570-modified hydroxylated boron nitride nanos...

pH ‐Sensitive Alginate/Polyvinyl Alcohol/Chitosan Crosslinked With Tetraethyl Orthosilicate Polymeric Hybrid Hydrogel for Biomedical Application

The main aim of this study was to develop a cost‐effective, pH‐sensitive Alginate (Alg), PVA, and chitosan (Cs) (Alg/PVA/Cs) hydrogel biocompatible polymer for controlled drug release of azithromycin. Tetraethyl orthosilicate (TEOS) was used to chemically crosslink the hydrogel, improving its structural integrity and...

One-step cured thermo-actuated Janus dressings with active self-peeling for atraumatic acne treatment.

Secondary mechanical trauma caused by the manual peeling or passive detachment of conventional adhesive dressings represents a key clinical challenge for fragile wound treatment. Herein, a thermally actuated Janus hydrogel was fabricated via sequential casting and one-step photopolymerization, leveraging macroscopic vi...

PDA-Assisted Fabrication of Calcium Alginate Hydrogel-Coated Stainless Steel Meshes for High-Efficiency Oil/Water Separation

This study introduces an environmentally friendly and straightforward dip-coating technique for preparing stainless steel meshes (SSM) coated with calcium alginate (CA) hydrogel. The prepared mesh possesses high hydrophilicity and underwater superoleophobicity, enabling highly efficient separation of diverse oil/wate...
