Tohoku Univ. Technology：CNF/Ag nanoparticle composite：T25-046
・Waste-free CNF/highly dispersed, high-loading AgNPs composite ・Catalysts, conductors, antimicrobials, thermal control, solder paste Overview
Cellulose nanofiber (CNF) and silver nanoparticle (AgNPs) composites serve as excellent dispersible carriers that maximize silver’s conductivity, catalytic activity, and antimicrobial performance. CNF, being plant-derived and environmentally friendly, also aligns with SDG goals. Conventional wet reduction methods, however, generate wastewater and require washing steps, leading to environmental issues and complex processing. This invention introduces an ultrasonication-based method that both disperses CNF uniformly and reduces silver oxide to form CNF/AgNPs composites without harmful reagents. The simple, waste-free process offers higher silver loading and better silver dispersion than conventional methods, enhancing silver’s inherent properties.
