Conservation of acidic papers using a dispersion of oleic acid-modified MgO nanoparticles in a non-polar solvent

In this study, a new method was developed for the deacidification of acidic papers, by using a deacidifying dispersion of oleic acid-modified magnesium oxide (MgO) nanoparticles in cyclohexane. We reported that oleic acid-modified MgO nanoparticles were prepared by using a surface modification method. The results showed that the carboxylic group of oleic acid could react with the hydroxyl group on the surface of nanoparticles and the reaction...
