Air-Liquid Foams,Concentrated Direct Emulsion and Soft Chemistry Toward Hierarchically Organized Porous Silica Monoliths

摘要

Hierarchically organized matter appears today a strong and highly competitive field of research mainly induced by the wide scope of applications expected.In this context,chemistry of shapes appears as a strong interdisciplinary field of research combining soft chemistry and soft matter.Hierarchical inorganic porous monoliths can be obtained using either air-liquid foams or biliquid foams as macroscopic patterns while lyotropic mesophases are employed to promote porosity at the mesoscale.By controlling the air-liquid foam's water liquid fraction or the emulsions oil fraction we can design the inorganic porous texture at the macroscale(i.e.cell sizes and shapes as well as the Plateau borders thickness).Those stategies lead to the formation of materials with characteristics that resemble aerogels.
