A new preparation method of nanolime dispersion for the conservation of artworks

The application of nanolime dispersions for consolidating wall paintings constitutes a valid alternative to the lime traditional ones. Particles size, polydispersion, and agglomeration depend on the preparation method. Tailoring the experimental condition of the synthesis, it is possible to produce nanodispersions for other specific artistic artworks such as stones, papers or woods. In this work a new preparation method, the insolubilisation-precipitation, will be shown. It was used to obtain nanoparticles dispersed in a water-isopropanol mixture. The stability of dispersion together with particle size and their morphology were found to be dependent on water to isopropanol ratio.
