Graphene 2-D Materials: Synthesis, Functions and Applications I
Wednesday, October 31, 2018 - 12:45pm to 1:00pm
Graphene and other 2D materials possess desirable mechanical and functional properties for incorporation into or onto novel colloidal particles, potentially granting them unique electronic and optical functions. However, this application has not yet been realized because conventional top-down lithography scales poorly for the production of colloidal solutions. Herein, we develop an âautoperforationâ technology providing a means of spontaneous assembly for colloidal microparticles comprised of 2D molecular surfaces at scale. Such particles demonstrate remarkable chemical, mechanical and thermal stability. They can function as aerosolizable and dispersible electronic particles capable of storing and transferring digital information, as well as recoverable microprobes for sensing and recording chemical information in water and soil.
