Embodiment 1

[0884] According to the ratio in Table 1, the organic-inorganic composite A was produced according to the following steps. The concentration of each component is a numerical value based on the total amount of each component. Table 2 shows the evaluation results of the obtained organic-inorganic composite A.

[0885] (1) Add 2.61% by mass of BPS modified ZrO to the Schlenk bottle with rotor 2 Particles, CuBr 0.045% by mass, CuBr 0.007% by mass 2 and 0.288% by mass of dNbpy.

[0886] (2) Connect a cooling tube to the Schlenk flask, vacuum the inside of the flask, and then replace it with nitrogen. Repeat this operation 3 times to deoxygenate the inside of the flask.

[0887] (3) Under nitrogen conditions, 97.05% by mass of MMA was introduced into the flask and stirred to prepare a reaction liquid.

[0888] (4) The flask was immersed in an oil bath at 60° C., and the reaction solution was stirred for 45 minutes to carry out polymerization reaction.

[0889] (5) After immersi...

Embodiment 2

[0918] The organic-inorganic composite B was produced in the same manner as in Example 1 in accordance with the composition in Table 1 except that the conditions of the polymerization reaction were 70° C. and 1 hour. Tables 2-4 show the evaluation results of the obtained organic-inorganic composite B, coating material, organic-inorganic composite film, and molded body.

[0919] MIBK was mixed with the organic-inorganic composite B, and a coating material and an organic-inorganic composite film (coating film) were obtained in the same manner as in Example 1. When the appearance of the obtained organic-inorganic composite film was visually confirmed, aggregation of particles was not seen, and transparency was maintained. When the refractive index of the obtained coating film was measured, it was 1.55, and compared with the pMMA of Comparative Example 1, the refractive index increased by 0.06. From this, it was found that the refractive index of the coating film can be controlle...

Embodiment 3

[0922] The organic-inorganic composite C was produced in the same manner as in Example 1 in accordance with the composition in Table 1 except that the polymerization reaction conditions were 90° C. and 7 hours. The evaluation results of the obtained organic-inorganic composite C, the coating material, the organic-inorganic composite film, and the molded article are shown in Tables 2-4.

[0923] Anisole was mixed with the organic-inorganic composite C, and a coating material was obtained by the above-mentioned method. Using the above coating material, an organic-inorganic composite film (coating film) was obtained in the same manner as in Example 1. When the appearance of the obtained coating film was visually confirmed, aggregation of particles was not seen, and transparency was maintained. When the refractive index of the obtained coating film was measured, it was 1.70, and compared with the pMMA of Comparative Example 1, the refractive index was increased by 0.21. From thi...

Abstract

The present invention relates to an organic / inorganic composite containing: particles of an inorganic compound; and a polymer bound to said particles. The molecular-weight distribution of said polymer is 2.3 or less, and the inorganic-compound particles constitute at most 96% of the total mass of the organic / inorganic composite. The present invention also relates to a thermoplastic composition, a coating material, an organic / inorganic composite film, and a photonic crystal containing the abovementioned organic / inorganic composite.

Description

technical field [0001] The present invention relates to an organic-inorganic composite and its manufacturing method, an organic-inorganic composite film and its manufacturing method, a photonic crystal, a coating material, a thermoplastic composition, a microstructure, an optical material, an anti-reflection component, and an optical lens. Background technique [0002] Optically transparent thermoplastic resins such as poly(methyl methacrylate) (hereinafter referred to as pMMA) and polycarbonate (hereinafter referred to as PC) are used for lenses and optical prisms, etc. due to their light weight and high productivity. Various optical components. [0003] However, although pMMA has small optical anisotropy, it has a low refractive index of about 1.49, so it is desired to develop a resin with a high refractive index. [0004] On the other hand, PC is often used in lenses and optical disks because its refractive index is about 1.59, but it has the disadvantages of high melt v...
