Abstract

In an embodiment of the present invention, a wet gel includes a crosslinked silicone resin in which a silicone resin composition is solidified; a first liquid capable of dissolving the silicone resin composition; and one of a solid capable of being dissolved in the first liquid, and a second liquid such that a degree of swelling, when the crosslinked silicone resin is immersed in the second liquid, is less than a degree of swelling when the crosslinked silicone resin is immersed in n-dodecane, wherein the second liquid is capable of being mixed with the first liquid.

First claim

The invention claimed is:

1. A wet gel comprising:
a crosslinked silicone resin in which a silicone resin composition is solidified;
a first liquid capable of dissolving the silicone resin composition; and
one of a solid capable of being dissolved in the first liquid, and a second liquid such that a degree of swelling, when the crosslinked silicone resin is immersed in the second liquid, is less than a degree of swelling when the crosslinked silicone resin is immersed in n-dodecane,
wherein the second liquid is capable of being mixed with the first liquid,
wherein the solid capable of being dissolved in the first liquid is tristearin or lotus leaf extract, and
wherein the second liquid is n-tetradecane, n-hexadecane, trichlorooctadecylsilane, polymethylphenylsiloxane or phenylmethylsiloxane-dimethylsiloxane copolymer.

2. The wet gel according to claim 1 , wherein the first liquid serves as the second liquid.

3. The wet gel according to claim 1 , wherein the silicone resin composition includes a chemical compound having a vinyl group and a chemical compound having a hydrosilyl group.

4. The wet gel according to claim 1 , wherein the first liquid is alkane, silicone oil, polymethylphenylsiloxane, toluene, tetraalkoxysilane or polyalkoxysiloxane.

5. The wet gel according to claim 1 , further comprising particles.

6. The wet gel according to claim 5 , wherein the particles are silica particles, alumina particles, silver particles, gold particles, platinum particles or magnetic particles.

7. A method of producing a wet gel comprising:
a process of solidifying a silicone resin composition in a presence of a first liquid capable of dissolving the silicone resin composition; and one of a solid capable of being dissolved in the first liquid, and a second liquid such that a degree of swelling, when a crosslinked silicone resin is immersed in the second liquid, the silicone resin composition being solidified in the crosslinked silicone resin, is less than a degree of swelling when the crosslinked silicone resin is immersed in n-dodecane,
wherein the second liquid is capable of being mixed with the first liquid,
wherein the solid capable of being dissolved in the first liquid is tristearin or lotus leaf extract, and
wherein the second liquid is n-tetradecane, n-hexadecane, trichlorooctadecylsilane, polymethylphenylsiloxane or phenylmethylsiloxane-dimethylsiloxane copolymer.

8. A product in which wet gel is formed on a surface of a solid, wherein the wet gel comprises:
a crosslinked silicone resin in which a silicone resin composition is solidified;
a first liquid capable of dissolving the silicone resin composition; and
one of the solid capable of being dissolved in the first liquid, and a second liquid such that a degree of swelling, when the crosslinked silicone resin is immersed in the second liquid, is less than a degree of swelling when the crosslinked silicone resin is immersed in n-dodecane,
wherein the second liquid is capable of being mixed with the first liquid,
wherein the solid capable of being dissolved in the first liquid is tristearin or lotus leaf extract, and
wherein the second liquid is n-tetradecane, n-hexadecane, trichlorooctadecylsilane, polymethylphenylsiloxane or phenylmethylsiloxane-dimethylsiloxane copolymer.
