  • Patent number: 11208351
    Abstract: Electromagnetically-induced cement concrete crack self-healing diisocyanate microcapsules include raw materials, in parts by weight, comprising 15-55 parts of petroleum resin, 5-10 parts of paraffin, 5-10 parts of polyethylene wax, 3-10 parts of magnetic iron powder and 20-67 parts of diisocyanate. The diisocyanate microcapsules use the diisocyanate as a core material, and the petroleum resin/paraffin/polyethylene wax/magnetic iron powder mixture as the shell of the capsule. When micro cracks occur in the concrete, the crack propagation can break partial of the microcapsule inside, the diisocyanate inside the microcapsules flows out and diffuses into the crack and is subjected to a solidifying reaction with water in the concrete, so that the crack is repaired in time; and for the microcapsules that are not broken by cracks, external electromagnetic field can be applied to melt the shell to release the diisocyanate inside, thereby diffusing into cracks and solidify with water to repair them.

  • Patent number: 11161747
    Abstract: Described are composite photonic materials that incorporate magnetic nanoparticles inside hollow or solvent-filled nano-scale or micro-scale shells and methods of making and using such composite photonic materials. When these photonic materials are present in a magnetic field, they exhibit a change in reflected, scattered, and/or transmitted light as compared to when the materials are not in the presence of the magnetic field. This results in the materials appearing to have a different color, such as when observed by the human eye or a light detecting device, such as a camera.
