Exploiting interfacial ionic mobility to make heat-moldable nanoparticle aggregates

Phys · · 511 words · By University
Nanotechnology Sustainable Manufacturing Materials Science

Researchers at The University of Osaka have developed a method to make nanoparticle aggregates, specifically cellulose nanofibers, thermoformable by introducing anionic groups and pairing them with cations from an ionic liquid. This process allows the materials to be molded into complex shapes using heat without compromising their structural integrity or properties.
