A METHOD FOR DEPOSITING A COLLOIDAL CRYSTAL HETERO-STRUCTURE ON A FLEXIBLE POLYMER SUBSTRATE

摘要

Disclosed herein is a method for fabricating a flexible colloidal crystal heterostructure. The method may include applying cold plasma treatment on a top surface of a flexible polymer substrate, horizontally depositing monodispersed polystyrene colloidal particles onto the top surface of the flexible polymer substrate, and creating a vertical temperature gradient in layers of monodispersed polystyrene colloidal particles. The vertical temperature gradient may be perpendicular to the top surface and may be created by heating an opposing bottom surface of the flexible polymer substrate.
