Title: Innovations of Narendra S Kadaba
Introduction
Narendra S Kadaba is a notable inventor based in Chestnut Hill, MA (US). He has made significant contributions to the field of light-polarizing materials, holding 2 patents that showcase his innovative approaches.
Latest Patents
His latest patents include a method for the manufacture of a light-polarizing polyvinylene sheet. This method provides a way to produce a polyvinylidene-based light polarizer, known as a 'K Sheet'-type polarizer. The process involves the acid-catalyzed dehydration of an oriented polymeric starting material, with the acid catalyst serving as a bonding agent to secure the starting material to a carrier web. The advantages of this method include reduced frequency of 'streaking' and 'mottling', good processing speed, and the ability to use a low acid concentration, resulting in a low-corrosion processing environment.
Another significant invention is the high-efficiency K-sheet polarizer. This invention relates to a new and improved light-polarizing sheet made from molecularly oriented polyvinyl alcohol, which contains oriented block segments of polyvinylene. The polarizing sheet comprises a polyvinyl alcohol/polyvinylene block copolymer material, where the polyvinylene blocks are formed by molecular dehydration of a sheet of polyvinyl alcohol. The design of this polarizing sheet allows for a uniform distribution of light-polarizing molecules, enhancing its effectiveness.
