Title: Innovations of Seung B Jun in Polyester Film Technology
Introduction
Seung B Jun is a notable inventor based in Kyunggi, South Korea. He has made significant contributions to the field of polyester film technology, holding two patents that showcase his innovative approach to material science.
Latest Patents
One of his latest patents is for a biaxially stretched polyester film. This film incorporates substantially spherical silica particles of colloidal state, with average diameters ranging from approximately 20 nm to 200 nm. These particles are present in amounts from approximately 0.005% to 1.0% by weight based on the total weight of the polyester. Additionally, alumina particles with average diameters ranging from approximately 50 nm to 500 nm are included, enhancing the film's surface properties such as slip property and abrasion resistance. This innovation allows for the manufacturing of final products without scratches and white powders. Another significant patent is for a method of preparing polyester suitable for film production. This method involves passing a dispersion-in-water type silica sol through a column of cation exchange resin to adjust the pH value, followed by the addition of a hydrogen bonding agent and ethylene glycol. The resulting silica sol is then used in the ester interchange reaction, ensuring excellent surface properties in the final polyester film.
