Transparent conductive material and transparent conductor
A transparent conductive material contains a conductive particle, a polyfunctional compound, and an organic compound having a side chain including an ester group, while the ester group is expressed by —COOR, where R is a substituted or unsubstituted alkyl group having a carbon atom number of 2 or greater.
1. A transparent conductive material comprising:
a conductive particle;
a polyfunctional compound; and
an organic compound having a side chain including an ester group;
wherein the ester group is expressed by the following formula:
—COOR
where R is a substituted or unsubstituted linear alkyl group having a carbon atom number of 2 or greater.
2. A transparent conductive material according to claim 1 , wherein the alkyl group is a fluorine-substituted alkyl group.
3. A transparent conductive material according to claim 1 , wherein the organic compound has a weight-average molecular weight of at least 100,000.
4. A transparent conductor comprising:
a conductive particle;
a crosslinked product; and
a binder resin having a side chain including an ester group;
wherein the ester group is expressed by the following formula:
—COOR
where R is a substituted or unsubstituted linear alkyl group having a carbon atom number of 2 or greater.
5. A transparent conductor according to claim 4 , wherein the alkyl group is a fluorine-substituted alkyl group.
6. A transparent conductive material according to claim 1 , wherein the organic compound comprises a non-crosslinked product.
7. A transparent conductor according to claim 4 , wherein the binder resin comprises a non-crosslinked product.
8.
