  • Flexible colloidal crystal heterostructure and manufacturing method thereof
    Patent number: 10875004
    Abstract: 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.
    Type: Grant
    Filed: August 1, 2018
    Date of Patent: December 29, 2020
    Inventors: Mohammad Mahdi Tehranchi, Zahra Sadat Azizi Yarand, Saeed Pourmahdian
