Embodiment 1

[0750] [Example 1: 20nmSiO 2 -g-p(TFEMA-co-PFPMA), thermoplastic]

[0751] 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. The evaluation results of the obtained organic-inorganic composite A are listed in Table 6.

[0752] (1) Add CuBr and CuBr to the Schlenk bottle with rotor 2 , carry out vacuum treatment on the inside of the flask and replace it with nitrogen. This operation is repeated 3 times. After deoxygenating the inside of the flask, a small amount of MIBK is introduced under nitrogen and stirred.

[0753] (2) Add PMDETA to the above solution, stir at 60° C., and use the obtained solution as a catalyst solution.

[0754] (3) BPS-modified 20-nm silica particles were put into another Schlenk bottle connected with a cooling tube and equipped with a rotor.

[0755] (4) Connect a cooling tube to the ...

Embodiment 2

[0776] [Example 2: 50nmSiO 2 -g-p(TFEMA / MMA / EA), thermoplastic]

[0777] Except having set the polymerization reaction conditions to 75 degreeC and 12 hours, the organic-inorganic composite B was manufactured by the method similar to Example 1 according to the compounding ratio of Table 1, and it evaluated. The evaluation results of the obtained organic-inorganic composite B are listed in Table 6. Since no chlorine was detected, the bromine content was expressed as the halogen content.

[0778] The number-average molecular weight (Mn) and mass-average molecular weight (Mw) of the polymer constituting the organic-inorganic composite B were measured by the above-mentioned method, and the results were Mn=14,200, Mw=21,900, and Mw / Mn=1.54. Polymer chains of uniform chain length are bound to the particles.

[0779] Using the organic-inorganic composite B, the solvent was changed to MIBK, and a coating material and an organic-inorganic composite film (coating film) were obtained ...

Embodiment 3

[0780] [Example 3: 50nm hollow SiO 2 -g-p(TFEMA-co-HEMA), thermoplastic]

[0781] Except having set the polymerization reaction conditions to 60 degreeC and 20 minutes, organic-inorganic composite C was manufactured by the method similar to Example 1 according to the composition of Table 1, and it evaluated. The evaluation results of the obtained organic-inorganic composite C are listed in Table 6. Since no chlorine was detected, the bromine content was expressed as the halogen content.

[0782] The organic-inorganic composite C was used, and a solvent in which MIBK and MEK were mixed at a ratio of 1:1 (volume ratio) was prepared by the above-mentioned method to obtain a coating material. At this time, ultrasonic treatment was performed for 3 hours. Furthermore, the coating film was produced by the method mentioned above. The evaluation results are listed in Table 9.

[0783] The external appearance was visually confirmed, and the aggregation of particles was not seen, an...

Abstract

An organic / inorganic composite film including an organic / inorganic composite containing inorganic compound particles and a polymer binding to the inorganic compound particles. Percentage of voids in the film is 3-70 vol% based on the volume of the film.

Description

technical field [0001] The present invention relates to an organic-inorganic composite and a method for producing the same, a coating material containing the organic-inorganic composite, an organic-inorganic composite film, and an antireflection member. Also, the present invention relates to an optical element, an optical component, and a lighting fixture including an organic-inorganic composite film. Background technique [0002] In the past, the control of the refractive index of films formed of polymers, coating films, etc. was carried out by introducing F atoms into the polymers, but there were problems such as limited control range and only soluble in special solvents. [0003] Therefore, as a method of further lowering the refractive index while maintaining the optical properties, attempts to disperse hollow inorganic particles in polymers have been actively conducted in recent years. In this case, the particles need to be uniformly dispersed in the polymer to provide...
