Abstract:

Several original methods for modifying the surfaces of cellulose fibers are reviewed including: (i) plasma discharge activation solvent-free grafting; (ii) reversible hydrophobic–hydrophilic tailoring of cellulose surface; (iii) ‘grafting from’ and ‘grafting onto’ fiber–matrix continuous chemical bonding composites through click-chemistry or living polymerization; (iv) layer-by-layer polyelectrolyte systems combined with the precipitation of metallic or metal oxides nanoparticles, in order to prepare hybrid materials with highly hydrophobic ...
