Title: Do Sung Kim: Innovator in Smart Window Technology
Introduction
Do Sung Kim is a prominent inventor based in Taejon, South Korea. He has made significant contributions to the field of smart window technology, holding 2 patents that showcase his innovative approach to enhancing light modulation in windows.
Latest Patents
One of his latest patents is a polymer film for smart windows. This invention relates to a polymer film that can modulate the intensity of light passing through a window, allowing users to control the amount of light entering a space. The film is prepared using a polyalkylacrylate dispersion polymer containing dispersed dichroic particles, synthesized through a reaction between nickel picolinate and polyiodide. The film medium polymer is created by dispersing these particles in a polymethylphenyl-dimethylsiloxane copolymer, utilizing dichlorodimethylsilane and dichloromethylphenylsilane as starting monomers. This innovative approach results in a film with enhanced compatibility, homogeneous dispersion of dichroic particles, and modulated light permeability, significantly increasing the film's transparency.
Another notable patent involves the development of dichroic particles for windows that vary the degree of light transmission based on user preference. These particles are created by reacting metal complexes of transition metals such as cobalt, nickel, and copper with picolinic acid and polyiodine. The resulting particles are dispersed in an acrylate-based polymer resin containing a plasticizer and are injected between two conductive sheets of glass. This technology improves stability under long exposure, enhances color fastness, and allows for rapid changes in light transmission in the presence or absence of an electric field.
