Abstract Polymer nanofibers exhibit unique nanoscale effects, high specific strength and modulus, exceptional design flexibility, large aspect ratios, substantial surface areas. These characteristics have drawn significant attention in emerging fields such as flexible electronics, 5G communications, new energy vehicles. Notably, poly( p‐ phenylene benzobisoxazole) (PNFs) present the best thermal stability flame retardancy among all known polymer nanofibers. Furthermore, due to highly oriented molecular chains orderly structure, PNFs demonstrate superior conductivity compared conventional nanofibers, thus garnering favor from researchers. This paper summarizes latest research progress of PNFs, detailing three preparation methods (electrospinning, mechanical dissociation, protonation) along with their respective advantages disadvantages. It also elucidates current development status applications retardancy, conduction, electrical insulation, electromagnetic shielding, battery separators, discusses challenges prospects faced by PNFs. aims provide theoretical guidance for application enhancing potential advanced applications, further expanding scope.

Multiple free-radical-trapping and hydrogen-bonding-enhanced polyurethane foams with long-lasting flame retardancy, aging resistance, and toughness

Materials Horizons, Год журнала: 2024, Номер 11(18), С. 4462 - 4471

Опубликована: Янв. 1, 2024

Flexible polyurethane foam (FPUF) is a ubiquitous material utilized in furniture cushions, mattresses, and various technical applications. Despite the widespread use, FPUF faces challenges maintaining long-lasting flame retardancy aging resistance, particularly harsh environments, while retaining mechanical robustness. Here, we present novel approach to address these issues by enhancing through multiple free-radical-trapping hydrogen-bonding mechanisms. A hindered amine phosphorus-containing polyol (DTAP) was designed chemically introduced into FPUF. The distinctive synergy between structures enables formation of hydrogen bonds with urethane, also effectively capturing free radicals across broad temperature spectrum. As result, incorporating only 5.1 wt% DTAP led successfully passing vertical burning tests witnessing notable enhancements tensile strength, elongation at break, tear strength. Even after enduring accelerated thermal for 168 hours, maintained exceptional properties. This study offers insights enhancement, simultaneously achieving outstanding retardancy, toughness, anti-aging performance.
