Impregnating an aniline monomer solution into wood and reacting polyaniline particles in-situ, in order to take advantage of the complex and robust structure of wood, has been investigated to a lesser degree. Of interest is also how the impregnation and reaction process affects the wood properties in terms of degradation of the material by the acidic impregnation solutions, where the polyaniline particles form within the wood anatomy, what amount of weight percent gains can be achieved, can a conductive veneer be achieved by this approach. In this study, the modification of wood is studied including the effect of the hydrophilic character of polyaniline on the dimensional stability of wood, if the particles leach from the material over time, and if wood becomes more flame retardant with the addition of polyaniline.
