“…In general, Japanese tissue or Chinese handmade paper is adhered to the blank side of a single-sided print to increase its mechanical strength. The polyester film encapsulation, silk lamination, and radiation polymerization are often used to improve the reinforcement of double-sided prints [16][17][18][19]. For the conservation of acidic historical paper documents, in general, two separate steps of deacidification and reinforcement are used.…”

To delay acidification and deterioration during natural aging, deacidification and reinforcement of paper manuscripts have been the most important technologies to prolong the life of objects. Herein, a novel approach for the conservation of paper manuscripts is proposed using chitosan nanoparticles as Lewis base that leads to both deacidification and strengthening of paper in one-step. Chitosan nanoparticles were prepared through physical ball grinding method and characterized via scanning electron microscopy (SEM), X-ray diffraction (XRD), laser particle size analyzer (LPSA), Fourier transform infrared spectroscopy (FTIR), and atomic force microscope (AFM). To evaluate the resistance of chitosan nanoparticle coating, the mechanical properties of paper after artificial aging were evaluated using dry heat and hygrothermal accelerated aging methods. The SEM, EDX, and X-ray Photoelectron Spectroscopy (XPS) were used to analyze the interaction mechanism between chitosan and Shuxuan paper. The results show that the coated paper had superior durability with respect to pH, tensile strength, and folding endurance. There was a presence of protonated amines in the form of ammonium salts due to ionic bindings with free H+ in the acidified paper, and the remaining –NH2 could be used as a base reserve. Finally, the resulting coated papers displayed good antibacterial properties.

“…A reinforcement process is needed to modify the mechanical performance of an old book to make it strong enough for holding/reading. The reinforcement generally includes the Viennese process (Cunha 1987), organosilane reagent (Ipert et al 2006;Souguir et al 2011;Souguir et al 2012), lamination (Letnar and Vodopivec 1997), sizing/impregnation (Leijonmarck et al 2013), paper splitting (Galinsky and Haberditzl 2004), and leafcasting (Kruth 1988). By implementing such reinforcement processes, the strength properties of old books can be improved obviously, and this may be a viable alternative or an addition to deacidification process in the preservation of paper.…”

Old books suffer from aging and deterioration spurred by acidification, oxidation, and other factors. To preserve these important historical documents, it is important to implement deacidification and reinforcement methods to extend their durability. In this study, microdroplets of 75 g/L sodium hydroxide solution were atomized before being utilized to neutralize acidity in the paper. As well, styrene acrylic latex was diluted to 10 times for atomization to function as a reinforcing agent. In addition to studying these methods individually, the effects of simultaneous deacidification and reinforcement were also studied.
