  • Publication number: 20240040759
    Abstract: A composite comprising a polymeric matrix and EM absorbers dispersed within the polymeric matrix. Each EM absorber comprises a dielectric flake, and a continuous magnetic coating on at least one major surface of the dielectric flake. The EM absorbers function as dielectric and magnetic absorbers in the 1-100 GHz frequency range. The composite can be used as an electromagnetic shielding article to mitigate electromagnetic interference in, for example, high speed, high frequency (HSHF) consumer electronics.

  • Patent number: 11597860
    Abstract: Magnetizable abrasive particles are described comprising ceramic particles having outer surfaces comprising a coating of unsintered polyion and magnetic particles bonded to the polyion. In favored embodiments, the magnetic particles have a magnetic saturation of at least 10, 15, 20, 25, 30, 35, 40, 45 or 50 emu/gram. In another embodiment, an abrasive article is described comprising a plurality of magnetizable abrasive particles as described herein retained in a binder material. Also described are method of making magnetizable abrasive particles and methods of making an abrasive article comprising magnetizable abrasive particles.

  • Publication number: 20230059388
    Abstract: A magnetic film includes a plurality of magnetically permeable particles dispersed between opposing first and second major surfaces of the magnetic film. The first and second major surfaces are spaced apart a distance D. The particles are agglomerated so as to form a plurality of substantially continuous layers of particles generally extending along orthogonal first and second directions and arranged along a third direction. Each substantially continuous layer of particles has a length L along the first direction from a first to an opposing second edge of the magnetic film and a width W along the second direction extending from the first to the second major surface. L/D?100.
