Any one of egg white and ice template.
According to the present invention, TiO2Sol preparation step is as follows:
S11, by diethanol amine (DEA) and dehydrated alcohol (C2H5OH it) mixes, by butyl titanate (Ti after mixing
(OC4H9)4) be slowly dropped into form solution A；
S12, deionized water and dehydrated alcohol are mixed to form B solution；
S13, respectively by A, B solution utilize magnetic stirrer 1-3h；
S14, B solution is slowly added to be stirred for 1-3h in A, ultimately forms colloidal sol；
Ti(OC4H9)4With H2The molar ratio of O is 0.25-4；
C2H5The molar ratio of OH and DEA is 6.6-60.
According to the present invention, SiO also can be selected in the crackle liquid2Any in colloidal sol, crackle nail polish, egg white and ice template
