Justin E. Poelma has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9081283
    Abstract: The invention disclosed herein provides highly efficient methods and materials useful for surface patterning via polymerization reactions. In particular, by using a light-mediated radical polymerization procedure, brush formation from a surface can be regulated spatially by controlling the area of irradiation. In embodiments of the invention, polymer chain length (and/or film thickness) can be effectively controlled by either the amount of time a surface is irradiated with light (temporal control) or by the intensity of light allowed to reach the surface. Such light-mediated control allows artisans to use the disclosed processes to form complex 3-dimensional structures on a variety of surfaces. Moreover, the simplicity of the disclosed polymerization processes allows them to be adapted for use in a wide range of technologies.
