A terminal extends from the base to exteriorly of the protective layer.
摘要:
A polymer composite includes a thermoplastic plastic polymer having a fine grain metal or metal oxide dispersed therein. Preferably, the fine grains has a size of about 1,000 nm or less. A method of making the polymer composite by adhering a metal layer to a thermoplastic polymer layer in a thermodynamically nonequilibrated condition followed by relaxation of the polymer layer to obtain thermodynamic equilibrium which causes the metal layer to be absorbed by the polymer layer as fine grains is also disclosed.
摘要:
A polymer composite contains colorant molecules dispersed therein. The colorant molecules can be dispersed in the polymer or bound to the polymer molecules. When the polymer is a polyamide, the polyamide is in a noncrystalline state due to the inhibition of crystallization imparted by the size and shape of the colorant molecules because the colorant is separated on a molecular level. A high colorant availability is obtained. A method of producing the polymer composite includes the steps of forming a metastable polymer resin layer, applying a film of colorant to the layer, stabilizing the layer, dissolving the stable layer in a solvent, aspirating the solution to remove impurities and aggregates and then removing the solvent. A polymer composition can be produced by mixing the polymer composite with a polymer.
摘要:
A particle dispersed glassy material includes ultrafine metal particles that are present in a high concentration. The particles are surrounded by a fixation component and, optionally, can be surrounded by a skeleton forming component. The glassy material is produced by firing a substrate having a film thereon that includes a polymer composite having the ultrafine particles uniformly dispersed therein, a fixation reagent and, optionally, a skeleton forming reagent under relatively mild conditions that do not damage the substrate. A method of making the glassy material includes the steps of making a film-forming composition that includes the polymer composite, the fixation reagent and, optionally, the skeleton forming reagent, applying the composition to a substrate, drying the applied composition to produce a film and firing the film to produce the glassy material.

A colorant of ultrafine particles for providing transparent color includes ultrafine metal particles, a fixing agent and a glass forming material. The ultrafine metal particles can be gas condensed ultrafine metal particles or polymer compound ultrafine metal particles. The colorant produces a transparent colored film on a substrate.
摘要:
A layer is provided for bonding a conductive plating to a substrate which substrate normally does not provide firm bonding of plating directly thereto. The bonding layer forms a matrix in which are dispersed ultrafine metal particles. The bonding layer is formed in situ on the substrate surface with the metal particles being maintained unaggregated in the matrix as it is formed on the surface. Plating subsequently formed on the outer surface of the bonding layer is effectively firmly bonded to the substrate through the intermediary of the matrix and metal particles distributed therein. The bonding layer includes a fixative formed of an organic compound including a metal and an organic solvent. The bonding layer may further include a film strengthener.
