Syntheses of Nano- and Micro- Particles for Direct-Writing

Direct-Writing （DI） or Direct-Ink-Writing （DIW） technique facilitates the fabrication of three-dimensional （3D） colloidal structures through layer-by-layer deposition rheological controlled particle-dispersed-inks. This offers superiority due to free choices particles. Various types particles including nanomaterials such as CNTs and graphene have been printed successfully by DI technique. In addition commercially available particles, it is also necessary synthesize unique that are elements emergence for 3D structural materials devices. Herein, we present a facile versatile platform approach syntheses single-nanosized, nearly monodispersed micron-sized, multicomponent nanosized based on hydrolysis polymerization under hydrothermal condition.
