Fabrication of Crosslinked and Reactive Nanoporous Polymer Coatings Using Spray-Based Methods

Abstract

This invention discloses spray-based methods for generating polymer-based coatings with a range of morphologies, chemical reactivities, and physical stabilities useful for a broad range of applications, such as for the fabrication of non-wetting and slippery surfaces. Certain embodiments of this invention provide coatings with nanoscale morphologies, physical stabilities, and chemical reactivities that are similar to or improved compared to analogous coatings and materials made using conventional dip coating or flow-based methods. These spray-based methods can also be used to fabricate coatings with substantially similar functional properties, but with improved consistency, efficiency, additional functionality, and reproducibility. In an aspect of the invention, two or more chemically reactive polymer solutions are sprayed onto a substrate to form a crosslinked polymer coating on the substrate. The polymer solutions may be applied to the substrate sequentially or simultaneously.
