“…The surface of the paper can be coated with polymer layer that contains nanoparticles which could fulfil the requirements of the OVP (Uglesic, 2015). The surface properties such as wettability, strength, water-vapor permeability as well as the optical properties (colour resistance to colour fading, ink density and print gloss (Afsharpour et al, 2017). To improve properties of the biodegradable material one usually adds some chemical compounds.…”

UV radiation or sunlight can affect the printed sample by fading the ink surface and therefore the product losses it's decorative purpose and becomes less desirable to the customer. To create the efficient protective coating, titanium dioxide (TiO2) will be used as a well-known compound that should lower the effects of UV radiation. TiO2 should lower the colour fade after UV radiation and this will be determined by densitometric and colorimetric (CIE L*a*b*) measurements. In addition, measurement of print gloss will also be conducted to evaluate visual appearance of the sample. Biopolymer Polycaprolactone (PCL) was the base of the PCL-TiO2 composite in which TiO2 nano sized. To determine influence of the amount of TiO2, three composites were prepared by adding different weight ratio of the TiO2. The prepared nanocomposites were then applied onto the offset prints on gloss art print paper and on the uncoated paper. The results have shown that TiO2 coating does affect ink’s density, colorimetric properties and print gloss after initial coating. The change in chroma due to the accelerated ageing is most visible on yellow ink, cyan and magenta proved to be the more stable. Accelerated ageing caused change in the L* of black. On all colours, increase of the TiO2 weight ratio improved resistance of colour to change. Coated gloss paper was more resistant to density change where uncoated had lower change in chroma. It could be concluded that TiO2 has the ability to protect the prints in the measured time interval but it has to be noted that concentration of the TiO2 particles also causes colour difference and must be observed when defining composure of the nanocomposite.

Collection paper in museums and libraries and stores suffer from acid hydrolysis and oxidations, many factors catalysis the deterioration by acid hydrolysis and oxidations, such as humidity and temperature and light and fungi, paper contains iron ink and colors based on ions heavy metals such as copper and zinc, air pollution, visible and industry light, Residues of manufacturing processes such as bleaching material, additives such as sizing materials, The study proposes a new antioxidants agent by using Line seed gel with magnesium bicarbonate loaded with Zinc oxide (NP), the positive impact of this treatment was evaluated on thermally accelerated ageing on cotton, linen and wooden samples, the samples was verified by FTIR, tensile strength and elongation measurement, Measurement of color change, PH measurement, aromatic hydroxylation assay, (SEM) scanning Electron microscope, Linseed gel with MgHCO 3 and Zinc oxide (NP) results to stabilize inks and stop oxidation that occurred and treatment of free radicals, the inks were most stable, The mechanical properties of the samples have been greatly improved, Linseed gel with magnesium bicarbonate loaded with Zinc oxide (NP) consolidation and treatment the samples, the zinc oxide (NP) nano oxide was observed between the fibers which works to protect the cellulose fibers From degradation.

“…Bisogna inoltre considerare che questi interventi possono portare a modifiche cromatiche del supporto. Ad esempio, la recente proposta di utilizzare ZnO, pur dando esiti promettenti in termini di prevenzione del biodeterioramento, comporta un lieve sbiadimento della carta (Afsharpour, Imani 2017). Analogamente, gli oli essenziali (olio di timo, ad esempio) pur mostrando una buona efficacia preventiva, impattano sul supporto modificandone il colore, mentre meno invasiva da questo punto di vista sembra essere l'applicazione di nanoparticelle di Ag (Pietrzak et al 2017).…”

IntroduzioneNell'ambito della conservazione dei materiali cellulosici, ridurre i fattori di rischio responsabili del degrado significa agire in termini di prevenzione; un adeguato monitoraggio ambientale rappresenta il primo ed essenziale atto concreto in questo senso (Federici 2009). Da questa logica e cogente considerazione derivano le attuali indicazioni e normative per una corretta conservazione del patrimonio librario. In questo breve testo vogliamo riassumere alcuni aspetti relativi al monitoraggio e riportare alcune esperienze di interventi di manutenzione considerandone gli aspetti di 'sostenibilità economica', tema d'interesse per archivi e biblioteche. Per capire l'impatto di una politica di prevenzione, al di là delle giuste considerazioni relative alle conseguenze derivanti dagli interventi di restauro sui supporti cellulosici, è necessario definire l'entità del patrimonio librario almeno a livello nazionale. MANUS è un database dei manoscritti in alfabeto latino prodotti dal medioevo all'età contemporanea conservati nelle biblioteche italiane pubbliche, ecclesiastiche e private. MANUS ha
