Geopolymers are synthetic inorganic polymers obtained from an aluminosilicate powder and an aqueous solution of alkaline hydroxides or silicates. The material is mesoporous and a multidimensional and functional porosity can be generated through the addition of fillers or the use of specific techniques.

The mix-design of the mixture, pure or composite, allows to change the chemical-physical properties of the final material, also thanks to the nucleation of zeolitic phases. Geopolymers also possess ion exchange and electrostatic interaction capabilities.

Flow technologies for the synthesis of chemical intermediates have great potential at the industrial level and the synthesis of nanoparticles (NPs) can speed up the development of new products. In this context, we could find the technology for the synthesis of NPs. The NPs (Au, Ag, or Pt) are synthesized in a single step and are functionalized with polymeric stabilizers (such as PVP, PVA, PEG, or others) or with thio-glycosidic fragments.

Chemical solution deposition of metal-organic precursors have favoured the research and development of thin films of simple and complex oxides such as Pb(Zr,Ti)O3, and Al2O3, up to their industrial application in pyroelectric and capacitor devices. Deposition methods used are spin-on and dip-coating. The advantages of the techniques are:

(i) low cost of equipment and chemicals

(ii) large area deposition

(iii) low crystallisation temperatures
