摘要:
Electromagnetic shielding material is formed from a shielding composition made with magnetic particles and a binder, where the magnetic particles have an average diameter less than about 1000 nm and are substantially crystalline. The magnetic particles can be formed from Fe2O3, Fe3O4, Fe3C, or Fe7C3. The shielding composition can be formed into a layer (500) or into composite particles (600). The binder (504) can be a metal or an electrically conducting polymer. A conducting layer (558) can be placed adjacent to the shielding composition. The shielding material can be used to protect sensitive electronic devices. Methods are described for forming iron oxide particles by laser pyrolysis.

A laminated soft magnetic member 5, which comprises a laminated body in which 1 µm or less thick soft magnetic metal layer 7 and an insulating layer 6 are laminated alternately and is 0.2 mm or less in overall thickness, is excellent in permeability in the high frequency band exceeding 800 MHz, and accordingly, by being attached,to a cellular phone, can improve the radiation efficiency of the electromagnetic wave on the side opposite to the head of a human body and is preferable as a member for the countermeasure against SAR.

Tôle multicouche utilisée pour le blindage électromagnétique possédant en outre des propriétés d'isolation thermique et phonique améliorées, caractérisée en ce qu'elle se compose de deux parements métalliques ferromagnétiques, entre lesquelles est insérée au moins une âme métallique ferromagnétique présentant une structure polygonale.
摘要:
A method of fabricating a support provided with shielding against interfering radiation, such as electromagnetic radiation, according to the invention involves a metallized plastic substrate, the metal comprising tin, being placed into an injection mould, and a plastic being injected into the mould to form the support. The tin-coated plastic substrate can be deformed very readily, so that it can be deformed three-dimensionally without its shielding characteristics being impaired.

The present invention provides a soft magnetic film having high saturation magnetic flux density and an excellent soft magnetic property in a high-frequency bandwidth of not less than several hundred MHz. The soft magnetic film contains Fe as a main component and M (at least one kind of element selected from 4A-group element, 5A-group element and 6A-group element), at least one of selected from Pt and Pd, and N.
摘要:
A composite magnetic tape which can be readily applied to electronic equipment regardless on the inside and outside of the equipment and can prevent the radiation and reflection of unnecessary electromagnetic waves from and to the inside of the equipment and, at the same time, can intercept electromagnetic noise from the outside. The tape can be formed in the form of an adhesive tape or autoadhesive tape. The tape is constituted of a composite magnetic layer formed by scattering soft magnetic power in an organic binder or in a laminated constitution of the composite magnetic layer and a conductive layer.
摘要:
A composition containing a polymeric matrix and a conductive filler component is provided. The conductive filler component comprises conductive particles and a polymer selected from the group consisting of substituted and unsubstituted polyanilines, substituted and unsubstituted polyparaphenylenevinylenes, substituted and unsubstituted polythiophenes, substituted and unsubstituted polyazines, substituted and unsubstituted polyparaphenylenes, substituted and unsubstituted polyfuranes, substituted and unsubstituted polypyrroles, substituted and unsubstituted polyselenophene, substituted and unsubstituted poly-p-phenylene sulfides and substiututed and unsubstituted polyacetylenes, and mixtures thereof, and copolymers thereof. Compositions of the present invention are useful as corrosion protecting layers for metal substrates, for electrostatic discharge protection, electromagnetic interference shielding, and as adhesives for interconnect technology as alternatives to solder interconnections. In addition, films of polyanilines are useful as corrosion protecting layers with or without the conductive metal particles.
