Surface and In-Depth Modification of Cellulose Fibers


This chapter is divided into three parts, according to the application envisaged for the modified fibers, namely (i) as reinforcing elements in macromolecular composite materials; (ii) in wood densification and protection; and (iii) for trapping organic pollutants. The major emphasis in the first part is devoted to the controversial aspects related to the interactions between cellulose and siloxanes. The second part illustrates our approach through the use of bifunctional coupling agents and the subsequent grafting of the densifying polymer. The third part shows how admicelles or aliphatic brushes, built around the fibers, play a useful role in capturing organic impurities from aqueous media.
