  • Organic-inorganic composite containing ceramic particles having fine projections on surface thereof
    Patent number: 9738771
    Abstract: An organic-inorganic composite including: a plurality of anisotropic ceramic particles having different aspect ratios; a resin that is combined with the ceramic particles; and a plurality of projections projecting out from the surface of the ceramic particles, thereby increasing the shear resistance of the interface between the ceramic particles and the resin. At least some of the ceramic particles neighboring each other are closely arranged such that the projections partially contact each other, thereby increasing the shear resistance between the ceramic particles due to the contacting ceramic particles.
    Type: Grant
    Filed: January 28, 2013
    Date of Patent: August 22, 2017
    Assignee: KOREA INSTITUTE OF CERAMIC ENGINEERING AND TECHNOLOGY
