Abstract
White A4 paper is used in our daily life to document printed and handwritten information. It is believed that through time, this paper will decompose hence indirectly contribute to the decomposition of any printed and handwritten texts stored on it. This study investigated the microscopic and spectroscopic characteristics of a set of white A4, 70 gms papers from five (5) different brands using Quanta FEG 450 Scanning Electron Microscopy and Bruker Tensor 27 Fourier Transform Infrared Spectroscopy (FTIR) equipped with Attenuated Total Reflectance (ATR) attachment. To study the effect of exposure to the environment, the papers were exposed at normal room condition (28°C) for 7, 14, 28 and 60 days. Upon completion of each exposure period, the papers were spectroscopically analysed. Two statistical tests which were Pearson’s Product Moment Correlation (PPMC) and Paired t-test were used to assess the effect of the exposure. PPMC showed strong positive correlation (with r > 0.99) while the Paired t-test showed no significant different between the exposed papers with their fresh counterparts when exposed up to 60 days. These findings indicated that the papers were unaffected, in other words relatively stable within the studied period of exposure i.e. up to 60 days.
