Title: Innovations of Jong-Seok Bark in Polymer Technology
Introduction
Jong-Seok Bark is a notable inventor based in Salt Lake City, UT (US), recognized for his contributions to polymer technology. He holds three patents that showcase his innovative approach to creating polymer blends with unique properties. His work is particularly significant in the field of drug delivery systems.
Latest Patents
One of Jong-Seok Bark's latest patents involves the development of polymer blends that swell in an acidic environment and deswell in a basic environment. This process includes dissolving chitosan and a second polymer in an acidic aqueous solution to form an aqueous polymer blend. The second polymer can be selected from various types, including polyether glycols, cellulose esters, poloxamers, polysaccharides, polyvinylpyrrolidones, and polyvinyl alcohols. These polymer blends are designed to swell in acidic conditions and return to their original state in neutral or basic environments. This technology is particularly valuable for the controlled dispensing of biologically active materials or drugs, especially in the gastrointestinal tract. Importantly, since the polymer blends are not covalently or ionically crosslinked, each polymer maintains its original chemical structure, ensuring safety for oral administration.
