chromophores and aging
Abstract
Cellulosic fibers differ strongly in their optical properties. The influence of process parameters and storage conditions on chromophore formation is of general interest in modern papers and in historic materials. In modern papers the understanding of chromophor structures will lead to improved methods for bleaching and fiber finishing. In the historic context the understanding of cellulose aging is necessary in order to develop appropriate methods for paper conservation. A widely-used approach to judge conservation treatments is accelerated aging under defined conditions. However, whether the aging method chosen reflects the natural conditions is still a widely discussed topic. The project aims at a deeper understanding of chromophore formation on a molecular level.
