Bridging Polymer Brushes and Coatings Through Ultra‐Thick Growth by Surface‐Initiated Photoiniferter Polymerization

open access: yesAdvanced Functional Materials, EarlyView.
Surface‐initiated photoiniferter‐mediated polymerization (SI‐PIMP) enables the controlled growth of UHMW polymer brushes with multi‐micrometer thicknesses, bridging conventional brushes and bulk‐like coatings. UHMW brushes are synthesized through a controlled/living process; they provide low friction and enhanced wear resistance under aqueous ...

Increasing Inter‐Micellar Connectivity Toughens and Imparts Cooling‐Induced Shape Memory in Micellar Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Oligomerizing Pluronic triblock copolymers provides a processing strategy for tuning the mechanical properties and stimuli‐responsive behaviors of micellar hydrogels. Varying oligomer fraction produces hydrogels spanning brittle to highly extensible responses; maintaining micellar architectures enables cooling‐induced reverse thermal shape memory and ...

Tough and Skin‐Free Porous Polyelectrolyte Complex Hydrogels via Salt‐Induced Aqueous Phase Separation

open access: yesAdvanced Functional Materials, EarlyView.
Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

open access: yesAdvanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed
