Paper is the most widely used writing support due to the remarkable properties of its principal componentcellulose -one of the most abundant biomaterials present on Earth. However, due to the complexity of the material, an exhaustive picture of its degradation pathways is still missing. In this paper, we will present recent results and progresses obtained in the comprehension of the role of cellulose oxidation in the yellowing of ancient paper. Visible and ultraviolet spectra of cellulose in ancient paper samples and reference modern samples artificially aged have been interpreted with the aid of ab-initio Time-Dependent Density Functional Theory calculations. Through the comparison of measured and calculated absorption spectra, several oxidized forms of cellulose polymers, acting as chromophores, and responsible for ancient paper yellowing were identified. The relative concentration of ketones and aldehydic groups depends on the environmental conditions in which samples were stored along their life.

“…In addition, hydrolysis produces acid molecules and thus, paper degradation accelerates. Recently the research group of Library Congress (USA) discovered that the cellulose itself of paper generates several low molecular weight acids, such as acetic, formic, lactic, and oxalic acids [36,37]. Most early papers, made from cotton and linen rags, are still strong and durable, while, papers produced from wood pulps (from the middle of XIX century) are more fragile and sensitive to the acidic hydrolysis due to the presence of lignin and hemicelluloses, more reactive than cellulose.…”

“…For samples aged in dry air, the changes in MWD are the least, the range of MMD curves is between 31.5 and 1000 kDa. It is not surprising that oxidation is a dominating reaction during ageing in dry air which has been observed in the literature for both silk and cellulose [18,53,67,68], which explains why depolymerisation of the polypeptide is not a prevailing reaction here. This oxidation can, however, bring about the chain breakage and in this way contribute to the drop in its molecular weight.…”

“…To spot possible degradation pathways, a thermal ageing in 90°C in oxygen atmosphere was applied, coupled with different humidity levels and in presence of VOCs. These factors are known to affect art materials at a different rate [18,30,33,40,49,51,[53][54][55]. The deterioration of silk fibres causes brittleness of the textile, resulting in loss of mechanical endurance.…”

Size exclusion chromatography (SEC), especially coupled with multiple angle laser light scattering detector (MALLS) is a powerful tool in diagnostics of deterioration of historic and art objects to evaluate their condition. In this paper, SEC-UV-MALLS-DRI technique was applied to study degradation of silk fibroin samples (Bombyx mori) artificially aged under various conditions: in the presence of oxygen, in different amount of water vapour and in volatile organic products (VOCs), all at temperature of 90°C. Conditions were chosen in such a way that it mimicked real conditions of textiles' storing during exhibitions and in show cases. The influence of temperature, moisture and VOCs content on the state of silk textiles was examined with the use of size exclusion chromatography. Pseudo-zero-order Ekenstam equation was applied to study degradation rates of fibroin with use of the approximated values of DP of fibroin.
