Aging cellulose and paper
The Chemistry of Ageing Processes of Paper and Cellulose

As defined in the introduction to this article by Fayolle and Verdu in [AM3150] , ageing is a phenomenon of slow, irreversible change in the structure and/or composition of a material due to its own instability, interaction with the environment (light, pollution, etc.) or mechanical stress.

Here, paper degradation is approached from a chemical point of view, and exclusively through the mechanisms of ageing as they occur under usual ambient conditions (natural hygrothermal ageing) or under standardized artificial ageing conditions (temperatures...
