Abstract
Invaluable heritage documents are largely affected by the influence of the environmental conditions, namely light, temperature, moisture and microorganisms. To prevent the damaging activity of these factors, a simple and non-invasive conservation method is the treatment of paper supports with different protective substances. The present study investigates the efficiency of a grafting treatment using the reactive derivative of a cyclic oligosaccharide, ?-cyclodextrin (i.e., monochlorotriazinyl-?-cyclodextrin). Due to their characteristic molecular structure, cyclodextrin and its derivatives may form inclusion compounds with a wide range of guest compounds (for their antimicrobial protective properties, ferulic acid, Michler’s ketone and allantoin were selected). The cellulosic support used was Japanese veil. Grafting of the reactive compound on the cellulosic paper support was realized by a relatively simple pad- dry-cure treatment, under mild conditions, while inclusion of the protective substances – by wet treatment with a guest solution. The treated supports were analysed by Fourier Transform-Infrared Attenuated Total Reflexion Spectroscopy (FT-IR ATR), Scanning Electronic Microscopy (SEM), tensile testing and by antimicrobial tests.
