Abstract
Polyurethanes stand out as remarkably versatile polymers, renowned for their adjustable mechanical and thermal characteristics, making them invaluable across various domains, notably in adhesive applications. Yet conventional polyurethane adhesives typically form permanent bonds, and thus debonding is not possible without harming the bonded substrates. In the light of escalating calls for sustainability, the development of polyurethane adhesives with debonding-on-demand capabilities has become paramount. Such innovations facilitate disassembly, repair, exchange, and recycling of bonded materials. Consequently, herein, we integrate three different linear acetal polyols into one-component, polyether-based polyurethane adhesives. These new systems not only exhibit comparable thermal properties and superior adhesive performance to conventional adhesives but also offer debonding-on-demand capabilities. These findings provide a drop-in solution to the limitations of traditional bonding methods and foster a circular economy, underscoring the pivotal role of adhesive technology in addressing environmental imperatives.
期刊介绍:
European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas:
Polymer synthesis and functionalization
• Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers.
Stimuli-responsive polymers
• Including shape memory and self-healing polymers.
Supramolecular polymers and self-assembly
• Molecular recognition and higher order polymer structures.
Renewable and sustainable polymers
• Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites.
Polymers at interfaces and surfaces
• Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications.
Biomedical applications and nanomedicine
• Polymers for regenerative medicine, drug delivery molecular release and gene therapy
The scope of European Polymer Journal no longer includes Polymer Physics.
