In this poster we present the synthesis of new hybrid materials constituted of a dual siloxane-polysaccharidic based materials by inter intertwining/cross-linking two polymeric epoxy-silane/polysaccharide based networks in aqueous solution ; using the carbohydrate framework as the building template for the siloxane polymerization. The advantage of cross-linkable sol-gel matrices over traditional sol-gel chemistry methods are primarily the use of low temperature processing to prepare the material, the opportunity to incorporate useful organic functionality into the final matrix, modified mechanical properties and partial and adjustable biodegradability. Depending on the starting silanes and polysaccharides these gels are cross-linked in a number of ways, to produce materials with unique, innovative and potentially valuable properties.
