Abstract
Optically transparent pressure-sensitive adhesives (PSAs) present several challenges. Conventional PSAs typically improve cohesive strength through chemical crosslinking; however, this approach not only reduces adhesion but also diminishes light transmittance. In this study, we explored hydrogen bonding crosslinking as a replacement for conventional chemical crosslinking and successfully synthesized the crosslinker UPyHCBA, which contains UPy units capable of forming self-complementary dimers through quadruple hydrogen bonds. A transparent acrylic PSAs incorporating the UPyHCBA monomer was then synthesized via solution polymerization. By modifying the ratio of UPyHCBA, we thoroughly investigated the impact of multiple hydrogen bonds on the molecular weight distribution, adhesive properties, thermal properties, light transmission, rheological behavior, and photoluminescence spectral properties of a specific optically transparent pressure-sensitive adhesive (PSAs).
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including:
polymer synthesis;
polymer reactions;
polymerization kinetics;
polymer physics;
morphology;
structure-property relationships;
polymer analysis and characterization;
physical and mechanical properties;
electrical and optical properties;
polymer processing and rheology;
application of polymers;
supramolecular science of polymers;
polymer composites.
