Provided is a dendritic silver-coated copper powder which is prevented from agglomeration, while ensuring excellent electrical conductivity by increasing contact points in cases where silver-coated dendritic copper powder particles are in contact with each other. This dendritic silver-coated copper powder is suitable for use in conductive pastes, electromagnetic shielding materials and the like. A dendritic silver-coated copper powder 1 according to the present invention has a dendritic form which comprises a linearly grown main trunk 2 and a plurality of branches 3 arising from the main trunk 2. The main trunk 2 and the branches 3 are configured of copper particles which have plate-like shapes having an average cross-sectional thickness of 0.2-1.0 μm, and the surfaces of which are coated with silver. This dendritic silver-coated copper powder 1 has an average particle diameter (D50) of 5.0-30 μm as determined by a laser diffraction/scattering particle size distribution measuring method.

Optical products and methods of making them are disclosed, the optical products comprising a polymeric substrate and a composite coating. The composite coating, in turn, comprises: a first layer comprising a polyionic binder, and a second layer comprising insoluble particles that absorb electromagnetic energy and insoluble particles that absorb relatively little visible light. Each of the first layer and the second layer includes a binding group component which together form a complimentary binding group pair.

Subwavelength conducting particles can be arranged on conducting surfaces to provide arbitrary thermal emissivity spectra. For example, a thermal emissivity spectrum can be tailored to suppress a thermal signature of an object without sacrificing radiative cooling efficiency.
