[0116] testing method
[0117] Determination of pore size
[0118] Pore size was determined using nitrogen adsorption assay. The material to be tested is coated onto a 100 mm diameter silicon wafer. The wafers were repeatedly coated using the spin-coating method, followed by calcination, as described in the Examples. The membrane was recovered and used in the nitrogen adsorption assay process. Total pore volume was measured by nitrogen adsorption using a gas sorption analyzer commercially available under the trade designation "QUANTACHROME AUTOSORB IC" (Quantachrom...

[0131] OTAB (0.126 grams), ethanol (2.102 grams), BTSBP (0.492 grams) and 0.1M HCl(aq) (0.201 grams) were combined in a polyethylene bottle.
[0132] Solution 2
[0133] OTAB (0.127 g), ethanol (2.129 g), BTSBP (0.445 g), PTMS (0.052 g) and 0.1M HCl(aq) (0.199 g) were combined in a polyethylene bottle.
[0134] Solution 3
[0135] OTAB (0.124 g), ethanol (2.106 g), BTSBP (0.392 g), PTMS (0.102 g) and 0.1M HCl(aq) (0.205 g) were combined in a polyethylene bottle.
[0136] Solution 4
[0137] OTAB (0.126 g), ethanol (2.112 g), BTSBP (0.352 g), PTMS (0.154 g) and 0.1M HCl(aq) (0.203 g) were combined in a polyethylene bottle.
[0138] Solution 5
[0139] OTAB (0.127 g), ethanol (2.095 g), BTSBP (0.300 g), PTMS (0.201 g) and 0.1M HCl(aq) (0.201 g) were combined ...
example 11
[0152] By vapor deposition of a 10 nm thick titanium layer to 25 x 25 mm 2 Slices of glass plates were used to prepare substrates. A 20 nm thick layer of silicon dioxide was coated onto the titanium layer by vapor deposition.
[0153] The coating solution was prepared by sequentially combining the following in a polyethylene bottle: OTAB (0.125 g), ethanol (2.102 g), BTSBP (0.398 g), PTMS (0.103 g) and 0.1 M HCl (aq) (0.201 g) .
[0154] A sample of this coating solution was used to prepare Example 11. After 121 minutes, the coating solution was spin coated onto the above substrate using a Headway Research EC101 DT-R790 spin coater with a 2 cm diameter suction cup. Use a few drops of the solution to diffuse over the sections before spin coating. Spin coating was performed at 1000 rpm for 60 seconds. The coated samples were calcined at a temperature of 450° C. in the air of a furnace.
