Natural Wax-Stabilized Perovskite Nanocrystals as Pen-on-Paper Inks and Doughs

Perovskite nanocrystals (PNCs) are emerging luminescent materials for a wide range of technological applications. The broad adaptation PNCs will be greatly improved by addressing their intrinsically low stability and developing processes assembly into 2D 3D structures using facile approaches. Inspired the mechanism natural protection leaves, this paper proposes carnauba wax (CW) as an encapsulation material PNCs. synthesis is performed in presence CW, which derived from leaves Copernicia prunifera palm. CW acts solvent replaces commonly used octadecene preparation results with thermal, water, air stability. Furthermore, thermal mechanical properties make PNC-Wax highly suitable solid ink versatile processing these architectures. can printed via pen-on-paper approach heating at modest temperatures. rapid plasticization agitation enables hand-shaping manner similar to playdoughs, would possibly enable use various
