摘要
The invention relates to a method for the treatment of cellulosic material. The method is comprising the steps of impregnation of the cellulosic material and treatment of the impregnated cellulosic material by a fumigation step or an evaporation step. Impregnation is performed with a metal ion M and at least one ion precursor Z yielding an impregnated cellulosic material. The at least one ion precursor Z provides an anion A or an anion A and a cation Y comprised within at least one metal salt solution I or with a metal salt solution II comprising a metal ion M. The fumigation or evaporation step is yielding a cellulosic composite material comprising a compound M(NH 4 )A, MYA or M(OH) x , wherein M is a metal.
