  • COLLOIDAL LITHOGRAPHY METHODS FOR FABRICATING MICROSCOPIC AND NANOSCOPIC PARTICLE PATTERNS ON SUBSTRATE SURFACES
    Publication number: 20140170310
    Abstract: A method of surface patterning by transferring particles interfacially trapped at an air-water interface to a substrate includes the steps of: (a) interfacially trapping a plurality of particles at an air-water interface; (b) providing a substrate having a polymer adhesive thereon, the polymer adhesive having a glass transition temperature that is less than 25° C. and an advancing water contact angle greater than 50; and (c) transferring the particles of step (a) to the substrate of (b) by the Langmuir-Schaefer technique.
