Wood protective fungicidal treatment: Quaternary ammonium molecules grafting on cellulose assisted by afterglows at atmospheric pressure

Résumé

Wood or cellulosic materials protection against fungi is possible by binding covalent molecules as quaternary ammonium compounds (QAC) on the hydroxyl reactive groups present in cellulose. This work firstly consists in the synthesis of a specific quaternary ammonium molecule containing a long aliphatic chain and an epoxide reactive group: Glycidyldimethyldodecylammonium chloride (GDDAC). Fungicidal properties of this molecule have been proven. Secondly, afterglows issued from atmospheric pressure Dielectric Barrier Discharges (DBDs), can assist QAC grafting on cellulose. The efficiency of the reaction is improved by adding a few percentage of oxygen in nitrogen DBD. Antifungal efficiency of GDDAC grafting on wood sawdust is finally shown demonstrating the great interest of such process. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
