Introduction

Dawn Marie Crawford is an accomplished inventor based in Bel Air, MD (US). She has made significant contributions to the field of polymeric materials, particularly in applications that require low visibility and enhanced performance. With a total of five patents to her name, her work is recognized for its innovative approach to solving complex problems.

Latest Patents

One of her latest patents is focused on ultra-violet cure coating. This invention provides several low observable aqueously dispersed polymeric materials with dual cure properties, utilizing both ambient and UV curing modalities. The compositions are suitable for coating substrates used in military, hunting, or other applications where low visibility is desired. The water-dispersible low observable curable composition includes an aqueously dispersed hydroxyl functional polyurethane resin and an aqueously dispersed urethane acrylate resin, along with one or more low solar absorbing pigments. These pigments are designed to be cobalt-free and do not absorb significant UV radiation during the curing process, thereby reducing the surface temperature and resulting in a low infrared signature.

Another notable patent involves highly sulfonated block copolymer hydrogels. This block copolymer composition features pendent groups extending from the A copolymer on at least 70 mol % of the A monomers, where R and Z are each an ionic species. This composition is included in a semipermeable membrane for use in direct methanol fuel cells. Additionally, articles of protective apparel comprising this composition exhibit barrier properties and superior water vapor transport capabilities.
