  • Patent number: 10786460
    Abstract: The present invention relates to a self-assembly preparation method of a nanocomposite material, and more particularly, relates to a self-assembly preparation method of a nanocomposite material comprising steps of: spraying a drug-containing solution onto metal aerosol nanoparticles to form a drug layer on the metal aerosol nanoparticles; and spraying a polymer-containing solution onto the metal aerosol nanoparticles, on which the drug layer is formed, to form a polymer layer on the drug layer, whereby since the method involves no liquid chemical process upon producing the metal aerosol nanoparticles, the processes are simple and can be performed even at a low temperature to suppress deformation of an organic or a drug, and the release rate of the drug, or the like can be easily controlled through metal types of metal aerosol nanoparticles, modification, and the like.

  • Patent number: 10655953
    Abstract: A structural color changeable material includes a strain body and surface plasmon generating particles. In the strain body, a strain is produced by an external pressure or an internal change. The surface plasmon generating particles generate surface plasmon and are contained in the strain body. The surface plasmon is generated by an incident light with a wavelength of 2400 nm or less. A mean particle size of the surface plasmon generating particles is equal to or less than the wavelength of the incident light. The surface plasmon generating particles are periodically arranged parallel to an in-plane direction of a reflection surface of the incident light.
