An inorganic organicity compound material constituent and the inorganic organicity hybrid material using it

Title:

An inorganic organicity compound material constituent and the inorganic organicity hybrid material using it

Document Type and Number:

Japanese Patent JP6170090

Kind Code:

B2

Abstract:

The disclosed inorganic-organic hybrid material can realize an optical material that combines the conflicting properties of flexibility and high index of refraction, has a low degree of yellowness, and is highly transparent. Said inorganic-organic hybrid material contains both an inorganic component and an organic component, with the inorganic component constituting between 20% and 80% of the mass of the inorganic-organic hybrid material, and has an index of refraction of at least 1.60. When said inorganic-organic hybrid material is used to fabricate a strip specimen 1,000 µm thick, 5 mm wide, and 70 mm long, said specimen does not crack when wrapped 180° around a cylindrical metal rod with a diameter of 10 mm at 25°C. Also disclosed is an inorganic-organic composite composition that contains: a radiation-curable monomer; inorganic particles that have crystallite diameters between 1 and 10 nm as calculated from the half-height width of a crystalline peak as per X-ray diffraction; and a sulfur-containing organic compound. The curable monomer includes a monofunctional radiation-curable monomer and a polyfunctional radiation-curable monomer. In terms of sulfur-atom content, the sulfur-containing organic compound constitutes between 1.5% and 10% of the inorganic-organic composite composition by mass.
