Fluoride‐Free Adhesives for Low Surface Energy Fluorinated Substrates

Advanced Functional Materials, EarlyView.
A universal, fluoride‐free adhesive achieves a record 4.91 MPa bond strength on PTFE by leveraging amine/amide dipole–dipole interactions, without fluorinated components. This sustainable strategy overcomes the environmental and performance limits of PFAS‐based adhesives, enabling robust, eco‐conscious bonding across diverse materials.

The effect of heterobifunctional crosslinkers on HEMA hydrogel modulus and toughness.

PLoS ONE, 2019
The use of hydrogels in load bearing applications is often limited by insufficient toughness. 2-Hydroxyethyl methacrylate (HEMA) based hydrogels are appealing for translational work, as they are affordable and the use of HEMA is FDA approved. Furthermore,

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus

Advanced Functional Materials, EarlyView.
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

Advanced Functional Materials, EarlyView.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.
