production of new films, organic chemistry inorganic nano structures from colloidal solutions of polysaccharide

摘要

the present invention describes a new process of synthesis, simple and environmentally friendly, and which allows easy access to the instance hierarchy of new materials in a single step.these inorganic organic hybrid materials, because they have the organic and inorganic phases are closely linked to the nano scale and do not exhibit heterogeneous areass and phase separation.the structural complexity of these materials is illustrated by the preparation of a wide range of hybrids based on polysaccharides and inorganic oxides including silica, ti02, fe203.sn02, zr02, zno, al 0, ge02 'v205, binary oxides type silica and silica - tio oxides (zr02, ternary phosphate - tio 2 - v205 type and type bati03et srti03 perovskites.
