| Abstract | ||
| The negatives are records and documents of monuments, social life and heritage to serve as witnesses and to tell the history of a time period for the present and the near and distant future. With the great development in the science of conservation and restoration of monuments and cultural heritage. Making the choice of different nanomaterials proposed to reinforce photographic negatives, they used nanomaterials from the same components of the photographic layer and compared their results with the best nanomaterials that have proven successful with glass antiquities (Silver Nano Nitrat - Nano Gelatin MatrialNano-Emulsion of Silver Nitrate with Gelatin -Nano Primal Composite with Nano Zinc). The evaluation is done by characterizing the physical and mechanical properties by measuring hardness, density, and dynamic light scattering (DLS). As well as analyzing the difference in surface area and pore size, as well as analyzing the angle of surface contact and knowing the resistance of these materials to moisture, As well as examining and analyzing through TEM,and Raman Spectroscopy. Through these examinations and analysis, it was found that silver nitrate gave the best consolidation results, followed by silver nitrate emulsion with gelatin, and in last place came the distortion of the external and internal appearance of the photographic layer Nanopremial with zinc oxide. The experiments proved that the best material to use is silver nanonitrate with a concentration of 3%. The process was applied to the historical negative B0641 from the collections of the Bella Photography Studio, which has a separation of the photographic layer from the glass holder in several places that were treated and strengthened with silver nanonitrate material. | ||
