文摘
- •
Electrophoretic deposition of synthetic opals templates from suspension of polystyrene nanospheres is described.
- •
These templates were used for electrochemically induced precipitation of Ni-Al-LDHs having inverse opal (IO) structures.
- •
The IO of the films survived heating at temperature high enough to convert the LDH into the corresponding mix oxides.
- •
The inverse opal LDH coatings have improved electrochromic properties compared to similar films lacking the opal structure.
- •
The color changes were more reversible when the IO films were heated to convert the LDH to mix oxides.
