Dr. Giuseppina Roviello from Dipartimento per le Tecnologie – Facoltà di Ingegneria, Università di Napoli ‘Parthenope’, Napoli, in Italy, presented her conference "Novel hybrid organic-geopolymer materials" during the Geopolymer Camp 2013, July 2013 in Saint-Quentin, France.
Novel hybrid organic–inorganic materials were prepared through an innovative synthesis approach based on a co-reticulation in mild conditions of epoxy based organic resins and an MK-based geopolymer inorganic matrix. A high compatibility between the organic and inorganic phases, even at appreciable concentration of resin, was realized up to micrometric level. These new materials present significantly enhanced compressive strengths and toughness.
It is based on the incorporation of the organic resin to the geopolymeric matrix suspension when both polymerization reactions are not yet completed. A good compatibility between the organic and the aqueous inorganic phases is obtained thanks to the numerous hydroxyl tails formed during the epoxy ring opening reaction that make the organic phase “temporarily hydrophilic” increasing the compatibility with the aqueous inorganic phase.
