Analysis of water condensation in P123 templated 2D hexagonal mesoporous silica films by X-ray reflectivity
Résumé
X-ray Reflectivity experiments have been used to characterize mesoporous silica thin films templated by the P123 EO30–PO70–EO30 (EO ethylene oxide, PO propylene oxide) triblock copolymer having the 2D hexagonal structure and to study the capillary condensation of water in such materials. A comparison with similar results obtained with films templated by CTAB is made.
