With a total of 2 patents, her work is paving the way for advancements in sustainable materials.

Latest Patents

D'Souza's latest patents include groundbreaking methods for producing carbon fibers from poly-(caffeyl alcohol) (PCFA). This material, also known as C-lignin, is a promising new source of both carbon fibers and pure carbon. The unique aspect of PCFA is that it can be used to produce carbon fibers through direct electrospinning, eliminating the need to blend with other polymers to reduce breakage. Analyses have shown that the carbon obtained from PCFA is superior to that derived from other lignins. The fibers formed from PCFA exhibit smoother surfaces, a narrower diameter distribution, and very low defects. PCFA can be extracted from plant seed coats, including those of the vanilla orchid. The fibers may be formed through electrospinning or other methods, such as extrusion with a carrier polymer, and can be carbonized to enhance carbon yield.

Another notable patent involves novel metal hydroxide derivatives that contain chemically bound organophosphorus or polyphosphate species as flame retardants. These derivatives combine positively charged metal hydroxide layers with negatively charged phosphorus-containing species, which can be either anionic organophosphorus materials or phosphorus-containing polymeric anions. The metal hydroxide derivatives serve as effective flame retardants due to their ability to disperse completely and form a crust or char that prevents flame propagation.
