Chemical Modification of Wood

resumo

The main emphasis of this chapter has to do with the shift from the traditional ways of treating woods in order to improve their resistance to atmospheric and biological degradation, to chemical modifications which eliminate the problem of leaching of toxic materials into the environment. Hence, recent contributions on the chemical modification of wood by different physico-chemical treatments, such as corona and plasma discharges, or its chemical grafting through esterification, etherification, as well as urethane and siloxane formation and the reaction of wood with furfuryl alcohol, are reviewed and discussed. The chapter also covers the topic of the preparation and characterization of composite materials made of wood fiber and polymeric matrices. These surface or bulk treatments point to the relevance of a novel green approach and show that very promising results can be obtained.
