Alternatively, use our A–Z index ostructured silica particles. In this investigation, ﬁve different plur-onics, P65, P85, P103, P123, and F127 have been used with CTAB as a co-surfactant. The CTAB/Pluronic mole ratio was varied from 0.0 to 10.0 to optimize the reaction conditions and to elucidate the ef-fect of CTAB in the formation of the mesostructured silica particles. Mesostructured photochromic pigments were synthesised by incorporating photochromic dyes in the organic domains of the surfactant templated inorganic/organic mesostructured silica particles. The pigments were produced using a one-pot synthesis method employing an aerosol reactor, allowing control over both the internal mesostructure and the dye content.

This synthesis method results in a high yield, and it is also suitable for studies of formation and growth mechanisms of colloidal mesostructured silica particles. It is now well-established that ordered mesoporous or mesostructured silica particles can be produced by exploiting the self assembly and subsequent liquid crystalline (LC) structures of surfactant molecules that develop as droplets undergo evaporation (evaporation-induced self assembly, EISA). The characterization results of mesostructured silica particles prepared at the early formation stages suggest that silica particles containing surfactants are initially deposited and that the mesostructure subsequently transformed from a disordered to an ordered one inside each silica particle. 2009-01-01 · Since its discovery in 1992, mesostructured silicate particles have been a subject of intensive research due to the large surface areas of the materials and the simplicity in modifying both the particle and the pore size. 38, 39 Various organic templates (e.g., cationic surfactants and triblock copolymers) and pore swelling agents have successfully been used in the particle synthesis to give a wide range of well-defined pore sizes and mesostructures.
