Abstract
Upgrading of fibre material in order to enhance the value or properties
of traditional paper and board products is a constant challenge for the
pulping industry. The presence of surface lignin in pulp fibres offers an
interesting possibility to the use oxidative enzymes such as laccases in
targeted modification of lignin-rich pulps. In the novel chemo-enzymatic
functionalisation method the enzymatic radical formation is exploited in fibre
activation and further functionalisation, i.e. bonding of new, desired
chemical components to the fibre material. Chemo-enzymatic functionalisation
opens up new perspectives both in current fibre product processing and in use
of wood pulps as a raw material in novel application areas. The mechanisms and
factors affecting the functionalisation of lignin-rich fibres have been
clarified in order to fully exploit the novel chemo-enzymatic
functionalisation method.
