Abstract

In this paper, we present the microwave-assisted synthesis and characterization of alkaline nanomaterials for the preservation of cultural heritage. Calcium and barium hydroxide nanomaterials suspended in aqueous as well as alcoholic medium were applied on different samples to check their effectiveness. The effect of treatment was measured using pH value and alkaline reserve test. The alkaline reserve test results indicate improvement in the alkaline buffer with significant reduction in acidity of the papers and improvement in pH value of the surfaces. Ethanol was found as best solvent on the basis of suspension of nanoparticles, pH value and ease of application through spray gun. Accelerated ageing test revealed that the reinforcement effect of these nanomaterials persisted throughout the ageing. All the results converged in individuating these nanometric particles as an innovative, completely compatible, and efficient material for the consolidation of old and new paper surfaces.
