Title: Innovations by Inventor Mrinal Thakur in Conductive Polymers
Introduction
Mrinal Thakur, an accomplished inventor located in Auburn, Alabama, has made significant contributions to the field of conductive polymers. With a total of 16 patents to her name, she is recognized for her innovative solutions, particularly in protecting against nuclear radiation and advancing photovoltaic technology.
Latest Patents
One of her latest patents focuses on nonconjugated conductive polymers that provide protection against nuclear radiation, including radioactive iodine. These polymers are designed to absorb radioactive iodine, which enhances safety in environments exposed to nuclear materials. They contain at least one double bond per repeat unit, and the ratio of double bonds to total bonds along the polymer chain is kept below half. Examples of these polymers include cis-1,4-polyisoprene (natural rubber), trans-1,4-polyisoprene (gutta percha), and styrene-butadiene rubber (SBR), to name a few. The interaction of iodine atoms with the double bonds in these polymers leads to the formation of radical cations, which turn the polymer dark while immobilizing the iodine atoms through charge-transfer interactions. These inexpensive polymers can be processed into various shapes and structures, making them extremely versatile for applications including thick covers for safe storage of nuclear waste materials, such as spent fuel rods.
In addition to her work on nuclear protection, Mrinal has developed photovoltaic applications using non-conjugated conductive polymers. One such invention consists of a photovoltaic structure that incorporates a glass substrate coated with a high work function metal, onto which a film of a non-conjugated conductive polymer combined with an electron acceptor (like fullerene or potassium iodide) is applied. This system includes a second electrode made from a low work function metal on the glass substrate. When exposed to light, this innovative structure generates an impressive electric voltage exceeding 100 mV for light intensities around 5 mW/cm.
