Abstract (en)
The invention relates to a lignocellulosic structure, to a process for producing a lignocellulosic structure, and to use of a boric acid derivatives in a lignocellulosic structure. The lignocellulosic structure of the invention comprises a layer with a thickness of 0.01 µm to 10 µm comprising SiO 2 on at least part of its surface, the structure being in the form of a honeycomb structure, and the structure being obtainable by contacting the lignocellulosic structure with a SiO 2 precursor, wherein the structure further comprising a boric acid derivative.
