Biomineralization, Geopolymers and Hybrid Nanocomposites
This chapter is dedicated to considering very peculiar nanotechnological systems, some of which are at present rather far from suitable applications in cultural heritage conservation; nevertheless they present interesting potential as new materials for art/architecture preservation. We will focus on biomineralization processes, where biological activity is used to consolidate stone materials thanks to the crystallization of calcium carbonate induced by microorganisms. It is interesting to underline that these methods have already originated important applications in cultural heritage conservation, and the literature shows that practical assessment is at a good stage. Concerning the other two subjects of the present chapter – geopolymers and organic–inorganic hybrid nanocomposites – the main chemical and physico‐structural properties will be analysed in order to investigate possible applications in cultural heritage conservation, namely in the field of preservation and restoration of works of art/architecture, and in climate and environmental control.
