Abstract:
The aim of this research is to study and compare the different effects of some natural and synthetic polymers dissolved in different solvents on sapwood and heartwood samples taken from an archaeological decayed Cupressus sempervirens, a gymnosperm wood that had been often imported into Egypt throughout history. Five commonly used adhesives were chosen for this purpose: Paraloid B 72 dissolved in acetone (3% w/v), Methyl cellulose dissolved in water (1.5% w/v), Funori dissolved in ethyl alcohol 70% (3% w/v), Gum Arabic dissolved in water (3% w/v) and Poly vinyl acetate (PVAc) diluted in water (50% v/v). Untreated sapwood and heartwood samples and treated sapwood samples were examined using scanning electron microscope (SEM-EDS). For monitoring the chemical changes and modifications, which occurred in the wood due to the chemical effects of the consolidants, untreated and treated sapwood and heartwood samples were analyzed with an FTIR spectrometer.
