  • Method of patterning a surface and articles comprising the same
    Patent number: 11383426
    Abstract: An article has a curved surface. Disposed upon the curved surface is a plurality of patterns. Each pattern is defined by a plurality of spaced apart features attached to or projected into the curved surface. The plurality of features each have at least one neighboring feature having a substantially different geometry, wherein an average spacing between adjacent features is about 1 nanometer and about 1 millimeter in at least a portion of the curved surface. The plurality of spaced apart features are represented by a periodic function.
    Type: Grant
    Filed: November 2, 2018
    Date of Patent: July 12, 2022
    Assignee: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.
    Inventors: Kenneth K. Chung, Anthony B. Brennan, Joseph W. Bagan, Mark M. Spiecker

  • Surface topographies for non-toxic bioadhesion control
    Patent number: 9016221
    Abstract: Disclosed herein is an article that includes a first plurality of spaced features. The spaced features are arranged in a plurality of groupings; the groupings of features include repeat units; the spaced features within a grouping are spaced apart at an average distance of about 1 nanometer to about 500 micrometers; each feature having a surface that is substantially parallel to a surface on a neighboring feature; each feature being separated from its neighboring feature; the groupings of features being arranged with respect to one another so as to define a tortuous pathway. The plurality of spaced features provide the article with an engineered roughness index of about 5 to about 20.
