Phase transformation from lamellar to hexagonal in mesostructured silica thin films by a water vapor hydrothermal method
The phase transformation from lamellar to 2-dimensional (2D) hexagonal structure has been observed in mesostructured silica thin films, synthesized using a self-assembly triblock copolymer (EO20PO70EO20, P123) as a template, during heat treatment under water vapor hydrothermal conditions.
