Interface copolymer-silicate

In the last years large attention was devoted to the synthesis and characterization of SBA-16 material focusing the interest on the formation mechanisms of copolymer micelles which drive the organization of the final siliceous mesostructure. In this framework, the physico-chemical properties at the interface between silica and triblock E0106P070E0106 co-polymer in a SBA-16 material were investigated. In particular, the combination of IR spectroscopy with SS NMR allowed to obtain complementary information on how the surfactant co-polymer interacts with the SBA-16 surface silanols in the presence or absence of physisorbed water and to follow the evolution of the structural organization of the co-polymer, which depends on the hydration degree of the SBA-16 sample.
