Abstract
With the features of easy-operation, fast-bonding and convenient recycling, thermoplastic polyurethane hot-melt adhesives are widely used in daily life and industry. However, thermoplastic polyurethane hot-melt adhesives face the deficiency of poor adhesion strength. Herein, we demonstrate a thermoplastic polyurethane hot-melt adhesive with high adhesion strength on a variety of substrates including metals and plastics under moderate operation conditions. Ascribed to the synergistic effect of the furan moieties in the backbone and the 2-ureido-4-pyrimidinone moieties in the side-chains, the synthesized polyurethane hot-melt adhesive realizes a high adhesion strength of 12.63 MPa. Meanwhile, this adhesive can maintain about 89% original adhesion strength after five recycling use. Besides, such adhesive has favorable tolerance to harsh conditions such as diverse liquids at extremely low temperature of −196 °C. It is expected that this polyurethane hot-melt adhesive has promising application.
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.
