Abstract:
A method of manufacturing an ultraviolet cross-linked foam insulated wire includes dissolving a gas in an ultraviolet curable resin composition, subsequently applying the ultraviolet curable resin composition on a conductor, and irradiating ultraviolet light on the ultraviolet curable resin composition to form a foam insulation layer on the conductor. The irradiating of ultraviolet light allows the resin composition to cure and bubbles to grow due to a decrease in solubility of the gas in the resin composition during the curing of the resin composition.
Abstract:
A composite metal fine particle material is provided, in which spherical silver nanoparticles synthesized from a silver compound, a solvent, a reducing agent, and a dispersant, and conductive fillers compose of non-spherical metal fine particles, are mixed. For example, the conductive fillers composed of the non-spherical metal fine particles are formed into slender columnar shapes, plate shapes, or ellipsoidal shapes.
Abstract:
There is provided an insulated wire equipped with an insulation film made of polymer alloy, the polymer alloy comprising an amorphous thermosetting resin and an amorphous thermoplastic resin, in which: the insulation film has a sea-island structure; the amorphous thermosetting resin is a sea component of the sea-island structure; and the amorphous thermoplastic resin is an island component of the sea-island structure.
Abstract:
A heat-resisting plastic optical fiber which excels in heat resistance and mass production and a manufacturing method thereof. The heat-resisting plastic optical fiber has a core which consists of transparent resin, and clad coated on the outer periphery of the core, which consists of the resin whose refractive index is lower than that of core. Precursor of material for the core material consists of the mixture of a group of monomers which contain polyfunctional monomer and transparent thermoplastic polymer.
Abstract:
An electromagnetic shielding material is formed of a tubular electromagnetic shielding material made of a vinyl based conductive polymer fiber represented by formula (2). The tubular electromagnetic shielding material is produced by forming a tubular compact made of a vinyl based conductive polymer precursor fiber represented by formula (1), and heating the tubular compact to eliminate a leaving group from the precursor fiber. where R1 represents an aromatic hydrocarbon group or a hetero hydrocarbon group, and R2 represents the leaving group.
