Hybrid organic-(bio)-inorganic materials will play a major role in the development of a new generation of advanced functional materials. Their improved and versatile features will lead to the development of innovative industrial applications. In order to design smart materials, soft chemistry based routes such as sol-gel techniques were investigated. In the sol-gel processing technique porous materials were obtained by synthesizing hydrogels based on widely used phenol as well as amino resin chemistries followed by ambient drying. We have extended this strategy to novel hybrid organic-inorganic materials using the former polymeric systems as gelation agents for inorganic precursors. The objective was to yield stable hybrid organic-inorganic materials as processable monoliths, films and microparticles.
