Examples
Embodiment 1
[0022] The composition of the nano sol glass antifogging agent is: 0.1wt% of silicon oxide compound sol; 0.01wt% of camptothecin compounds with the structure shown in formula I; and 99.89wt% of water.
[0023]
[0024]
[0025] Wherein, R is selected from any one of C1-C5 alkyl group, carboxyl group, ester group and amino group.
[0026] The anti-fog agent formulated in this example can extend the anti-fog time to 8 months, which fully meets the application requirements. When the solvent is ethanol, methanol, propanol, acetone, ethyl acetate, petroleum ether, the anti-fog time of about 8 months can still be obtained.
Embodiment 2
[0028] The composition of the nano sol glass antifogging agent is: 15wt% of titanium oxide compound sol; 2wt% of camptothecin compounds with the structure shown in formula I; and 83wt% of water.
[0029]
[0030] Wherein, R is selected from any one of C1-C5 alkyl group, carboxyl group, ester group and amino group.
[0031] The antifogging agent prepared by the method can extend the antifogging time to 8 months, fully meeting the application requirements. When the solvent is ethanol, methanol, propanol, acetone, ethyl acetate, petroleum ether, the anti-fog time of about 8 months can still be obtained.
Embodiment 3
[0033] The composition of the nano sol glass antifogging agent is: 30 wt% of aluminum oxide compound sol; 4 wt% of camptothecin compounds with the structure shown in formula I; and 66 wt% of water.
[0034]
[0035] Wherein, R is selected from any one of C1-C5 alkyl group, carboxyl group, ester group and amino group.
[0036] The antifogging agent prepared by the method can extend the antifogging time to 8 months, fully meeting the application requirements. When the solvent is ethanol, methanol, propanol, acetone, ethyl acetate, petroleum ether, the anti-fog time of about 8 months can still be obtained.
