Reversible buckling and diffusion properties of silica-coated hydrogel particles

Original language description

The structure and diffusion properties of composite particles consisting of a calcium alginate hydrogel core and a thin SiO2 surface layer have been investigated. The composite particles were formed by depositing a silica layer onto calcium alginate cores using a sol-gel process starting from alkoxysilane precursors. The composite particles were found to have a remarkable ability to reversibly rehydrate and return to their original size and shape after partial drying. The organo-silica skin was able tosustain large local deformations (such as complete folding) without the formation of cracks or defects. Such mechanical properties are uncharacteristic of pure silica and they can be attributed to the specific microstructure of the alginate-silica composite. The structure and composition of the alginate-silica particles were characterised by SEM, X-ray micro-tomography, Laser Scanning Confocal Microscopy and Thermo-gravimetry. In order to quantify the effect of the organo-silica layer on
