Hydrogel is a polymer network system that can form hydrophilic three-dimensional structure through different cross-linking methods. In recent years, hydrogels have received considerable attention due to their good biocompatibility and biodegradability by introducing mechanisms functional components. Compared with synthetic hydrogels, natural polymer-based low biotoxicity, high cell affinity, gr...

Front Cover: In article 2200456 by Clément Mugemana and co-workers, adhesive films prepared from polydopamine-functionalized polydimethylsiloxane polymer co-networks with tunable stiffness nanoscale phase-separated morphologies are presented.

Introduction In wood industry, adhesive bonding is one of the key process steps. To ensure continuing technological progress in wood industry it is necessary to explore new possibilities of improvement in adhesive bonding. The potential routes for performance improvements suggested by a state of the art report issued by COST Action E13 Wood Adhesion and Glued Products (Dunky et al. 2002) focus ...

Abstract Transfer printing based on switchable adhesive that heterogeneously integrates materials is essential to develop novel electronic systems, such as flexible electronics and micro LED displays. Here, we report a robust design of thermal actuated dry adhesive, which features stiff sphere embedded in thermally responsive shape memory polymer (SMP) substrate encapsulated by an elastomeric m...

Transdermal patches are a popular route for drug delivery because of the sustained drug levels, low side effects, reduced hepatitic first-pass effect and ease of use, including self– administration. The basic components of any transdermal delivery system include one or more active pharmaceutical ingredient s (APIs) dissolved or dispersed in a reservoir or inert polymer matrix; an outer backing ...

The ability to spatially control cellular adhesion in a continuous manner on a biocompatible substrate is an important factor in designing new biomaterials for use in wound healing and tissue engineering applications. In this work, a novel method of engineering cell-adhesive RGD-ligand density gradients to control specific cell adhesion across a substrate is presented. Polymer brushes exhibitin...

The behavior of microencapsulated polymerization initiators in dental adhesives is unknown. This study investigated the effects of new microencapsulated initiators in novel, multi-purpose, PMMA-type adhesive resin on the bonding performance and polymerization reactivity. Microencapsulated BPO and 1,3,5-trimethylbarbituric acid (TMBA) with PEMA as a shell polymer were quantitatively synthesized ...
