Patent number: 11985805Abstract: A thermally conductive electromagnetically absorbing material includes a plurality of particles dispersed in a binder. The plurality of particles can have a particle size distribution having at least three peaks, where at least a majority of particles within a half width at half maximum of one, but not the other ones, of the at least three peaks are at least partially coated with an electromagnetically absorbing coating. The plurality of particles can include pluralities of first and second particles where a total number of the first particles is at most 1% of a total number of the first and second particles and where the first particles are more electromagnetically absorbing than the second particles. Films, molded articles and systems including the thermally conductive electromagnetically absorbing material are described.Type: GrantFiled: March 23, 2021Date of Patent: May 14, 2024Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Zhonghua Lu, Badri Veeraraghavan, Joel S. Peiffer, Jeffrey A. Tostenrude, Jaewon Kim, Zulfiqar A. Khan, Jennifer J. Sokol

Publication number: 20240150551Abstract: The present disclosure provides compositions, articles, and methods related to altering electromagnetic radiation. An actinic radiation curable precursor composition of a three-dimensional article includes a) a resin comprising an actinic radiation curable component, wherein the resin has a viscosity no greater than 500 cP; b) hollow glass microspheres having a density no greater than 2 g/mL and an average diameter no greater than 200 micrometers; and c) a photoinitiator. At least part of the surface of the hollow glass microspheres comprises a surface coating or modification. An article includes a photo(co)polymerization reaction product of the composition. A method of manufacturing a three-dimensional article includes the steps of a) providing an actinic radiation curable precursor composition; and b) selectively exposing a portion of the composition to a source of actinic radiation to at least partially cure the exposed portion of the composition, thereby forming a cured layer.Type: ApplicationFiled: March 31, 2022Publication date: May 9, 2024Inventors: Tom Gaide, Jens Eichler, Christian Weinmann, Friedrich M.

Patent number: 11962367Abstract: An antenna for transfer of information or energy is described. The antenna includes an electrically conductive first layer having a width in a thickness direction of the antenna and extending longitudinally along a length of the first layer between first and second longitudinal ends of the first layer, and an electrically insulative thermally conductive second layer bonded to the first layer along the length of the first layer. The first and second layers are wound to form a plurality of substantially concentric loops. A width and a length of the second layer are substantially co-extensive with the respective width and length of the first layer so as to expose opposing longitudinal edge surfaces of the first layer along the length of the first layer. Coils and assemblies useful for making coils are also described.Type: GrantFiled: February 24, 2021Date of Patent: April 16, 2024Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Seong-Woo Woo, Jinwook Kim, Jung Ju Suh, Jennifer J.

Patent number: 11664850Abstract: A coil for transfer of information or energy is described. The coil includes an electrically conductive magnetically insulative first layer and a magnetically conductive second layer bonded to the first layer along the length of the first layer. The first and second layers are wound to form a plurality of substantially concentric loops. A width and a length of the second layer may be substantially co-extensive with a respective width and length of the first layer so as to expose opposing longitudinal edge surfaces of the first layer along the length of the first layer. At least one of the opposing longitudinal edge surfaces may include a regular pattern extending substantially along a same first direction and across substantially the entire coil. A method of making the coil is described.Type: GrantFiled: August 28, 2019Date of Patent: May 30, 2023Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Seong-Woo Woo, Jinwook Kim, Charles L.
