Title: Jo Marshall: Innovator in Anti-Fog Compositions
Introduction
Jo Marshall is a notable inventor based in Lichfield, GB. She has made significant contributions to the field of anti-fog compositions, holding a total of 2 patents. Her innovative work focuses on enhancing the performance of materials used in various applications.
Latest Patents
Jo's latest patents include groundbreaking anti-fog compositions and processes for making them. One of her inventions involves anti-fog compositions that comprise a primary film with opposing major planar surfaces and a central coplanar region. This central region is strategically placed between the two surfaces and consists of cellulose acetate, a plasticizer, and an anti-blocking agent. The anti-blocking agent has an average particle size ranging from 0.02 microns to 6 microns. The cellulose acetate used in her compositions has a degree of substitution that either increases toward the central coplanar region or remains constant throughout the thickness of the composition. The process of forming this composition includes saponifying a precursor film to enhance hydrophilicity.
Another patent focuses on similar anti-fog compositions, which also include a primary film with a thickness greater than 90 microns. The cellulose acetate in this composition may have a degree of substitution of less than 2.6, and the plasticizer can be selected from a variety of compounds, including triacetin and tributyl citrate.
