Ester, regulation pH value is 9 ~ 10, and reaction temperature is 20 ~ 25 DEG C, reacts 60 ~ 90min；It is centrifuged and successively with acetone and deionization
Water cleans and obtains precipitation；This is deposited at 90 DEG C and is dried 3h, to obtain nano polyaniline/photochromic flour complexes/SiO2；
By nano polyaniline/photochromic flour complexes/SiO2It is placed under argon gas atmosphere and carries out 800 ~ 1000 DEG C of heat treatment 1 ~ 2h, remove
Polyaniline, photochromic powder/porous SiO2, the most photochromic complex.
