  • Patent number: 11396598
    Abstract: A polybutylene succinate (PBS) nanocomposite material includes a matrix comprising polybutylene succinate chains, and nanocelluloses dispersed between the polybutylene succinate chains. The PBS composite material may be produced by polymerizing 1,4-butanediol and succinic acid or a derivative thereof in a mixture of 1,4-butanediol and succinic acid or a derivative thereof with nanocelluloses. The PBS nanocomposite material and the method have improved properties, which does not require a surface hydrophobization pretreatment process of cellulose, melt kneading, and solution mixing processes.

  • Patent number: 10954435
    Abstract: The present invention relates to a luminescent rare earth compound and dichroism fluorescent composition thereof, and more particularly, the luminescent rare earth compound is a luminescent rare earth compound excited by shortwave UV (Ultra-Violet). The luminescent rare earth compound and/or products applied with the luminescent rare earth compound according to the present invention can emit strong red and green colors by being excited at 240-330 nm range of wavelengths, while not being excited at 360-380 nm range of wavelengths, and showing no colors under visible light. Furthermore, the compound may be variably utilized to printed materials and plastic mold products because of possessing high heat resistance, high light resistance and high dispersibility of medium light.

  • Patent number: 10050214
    Abstract: The present invention relates to a near-ultraviolet stimulated light-emitting compound, and more specifically relates to a fluorescent quinazolinone compound which is stimulated in the near ultraviolet region. The fluorescent quinazolinone compound according to the present invention is colorless in daylight but exhibits a high fluorescent intensity when irradiated with light in the near ultraviolet region. Also, the fluorescent quinazolinone compound can be easily used with printed and plastic molded products since the compound not only has a high degree of light fastness and thermal stability but also high dispersibility.
