Abstract

Disclosed an organic-inorganic hybrid composition including a polymer (A) including a triazine ring structure represented by General Formula (1) in a polymer main chain structure;

wherein, in the formula, R1 is a substituted or unsubstituted alkyl group, aryl group, aralkyl group, amino group, arylamino group, alkylthio group, or arylthio group,
an inorganic particulate (B); and
a surface-treatment agent (C) including an acidic functional group
wherein the polymer (A) is a thermoplastic polymer having a glass transition temperature (Tg) and a number median diameter (Dn50) of the inorganic particulate (B) is greater than or equal to about 1 nm and less than or equal to about 20 nm, and an article and an optical component including the organic-inorganic hybrid composition.

First claim

What is claimed is:

1. An organic-inorganic hybrid composition comprising
a polymer (A) including a triazine ring structure represented by General Formula (1) in a polymer main chain structure;

(wherein, in the formula, R 1 is a substituted or unsubstituted alkyl group, aryl group, aralkyl group, amino group, arylamino group, alkylthio group, or arylthio group)
an inorganic particulate (B); and
a surface-treatment agent (C) including an acidic functional group
wherein the polymer (A) is a thermoplastic polymer having a glass transition temperature (Tg),
a number median diameter (Dn50) of the inorganic particulate (B) is greater than or equal to about 1 nm and less than or equal to about 20 nm.

2. The organic-inorganic hybrid composition of claim 1 , wherein a glass transition temperature (Tg) of the polymer (A) is greater than or equal to about 80° C. and less than or equal to about 200° C.

3. The organic-inorganic hybrid composition of claim 1 , wherein the triazine ring structure is represented by General Formula (2)

(wherein, in the formula, R 2 is independently a divalent group having an aromatic ring).

4. The organic-inorganic hybrid composition of claim 1 , wherein the R 1 includes a carboxyl group.

5. The organic-inorganic hybrid composition of claim 3 , wherein the R 2 is represented by the following formula

(wherein in formula, R is independently a substituted or unsubstituted alkylene group).

6. The organic-inorganic hybrid composition of claim 1 , wherein the acidic functional group of the surface-treatment agent (C) is a carboxyl group.

7. The organic-inorganic hybrid composition of claim 1 , wherein a refractive index of the inorganic particulate (B) is greater than or equal to about 1.8 and less than or equal to about 3.0.

8. The organic-inorganic hybrid composition of claim 1 , wherein the inorganic particulate (B) includes at least one particle selected from zirconium oxide, titanium oxide, barium titanate, strontium titanate, and zinc oxide.

9. The organic-inorganic hybrid composition of claim 1 , wherein an amount sum of the inorganic particulate (B) and the surface-treatment agent (C) is in a range of greater than or equal to about 5 wt % to less than about 80 wt % based on about 100 wt % of a sum of the polymer (A), the inorganic particulate (B), and the surface-treatment agent (C).

10. The organic-inorganic hybrid composition of claim 1 , wherein a refractive index (nd) (587.6 nm) is greater than or equal to about 1.7.

11. An article comprising the organic-inorganic hybrid composition of claim 1 .

12. An optical component comprising the organic-inorganic hybrid composition of claim 1 .
