Geopolymer-​silicon hybrid materials for high temperature applications and its preparation method

The present invention provides a material that is obtained from (i) an alluminosilicic source, (ii) a mixt. of siloxanic monomers and oligomers with different d.p., and (iii) an alk. activating soln. The reagents, by means of an appropriate process that realizes in situ co-​crosslinking, result in obtaining a material characterized by a homogeneous dispersion at the nanometric level of the components and the absence of phase sepn. The hybrids can be used as or in the form of low-​d. solid foam, heat-​insulating and heat-​resistant elements in structural panels, and not in the manuf. of high temp. resistant coatings, adhesives, mortars for the construction and for other technol. advanced uses.
