Examples
example 1
[0025] example 1 - Gold in MTMS / TEOS
[0026] The sol-gel hydrolysis mixture was obtained by mixing 4.3 g of ethanol, 40.0 g of methyltrimethoxysilane (methyltrimethoxy silane) (MTMS), 0.86 g of tetraethoxysilane (TEOS) and 0.14 g of water in 32.0 g of water. .1M acetic acid and subjecting the mixture to hydrolysis for 48 hours.
[0027] Fe 2 o 3 The dispersion is obtained by mixing 3g Fe 2 o 3 , 3g Dysperbyk-190, 7g water and 10g ethanol. And this dispersion was added to the sol-gel hydrolysis mixture and methoxypropanol in a ratio of 1:2:0.2. Spin-coating the resulting solution on a glass plate or spraying it onto a rotating glass shell will yield a 2 o 3 2 µm thick coating.
[0028] Subsequently, 1 g of Au particle dispersion comprising 25 wt% gold particles, 7 wt% polymer and 68 wt% ethanol was mixed with a sol-gel hydrolysis mixture similar to the above in a ratio of 1 to 2. The polymer used to stabilize the metal particles is a polystyrene-polycarbonate block ...

[0031] Example 2 -Silver in TEOTi
[0032] First, as in Example 1, a 2-micron-thick coating containing about 20vol.% Fe 2 o 3 silicon oxide layer.
[0033] A sol-gel hydrolysis mixture was prepared by mixing 20 g of ethanol, 3.3 g of tetraethoxytitanium (TEOTi) and 2.35 g of 0.1 M HCL (hydrochloric acid) and hydrolyzing the mixture for 48 hours.
[0034] Subsequently, 1 g of Ag particle dispersion including 17 wt % silver particles, 13 wt % polymer and 70 wt % ethanol was added to 2 g ethanol and 2.5 g of 10 wt % N-aminopropyltrimethoxysilane dissolved in ethanol. This solution was mixed with the TEOTi solution in a ratio of 1:2. The polymer used to stabilize the metal particles is a polystyrene-polycarbonate block copolymer.
[0035] A coating liquid was prepared by mixing the silver solution and the sol-gel hydrolysis mixture. The coating liquid was then spin-coated onto the Fe-containing 2 o 3 coated glass substrates and cured in air at a temperature of 350°C. The...
