摘要:
The invention relates to a method for treatment of cellulose-based material comprising a coupling step and a hydrophobization step. The coupling step comprises the provision of a coupling solution comprising titanium(IV) isopropoxide (TTIP) or a basic solution of zinc oxide and the immersion of the cellulose-based material into the coupling solution. The following hydrophobization step comprises the provision of a hydrophobization solution comprising a hydrophobic compound and the immersion of the cellulose-based material in the hydrophobization solution, yielding a hydrophobic cellulose-based material, followed by drying of the hydrophobic cellulose-based material. According to a second aspect of the invention a cellulose-based material is provided characterized by its omniphobic properties, a cellulose-TTIP hybrid layer and/or ZnO hybrid layer.
摘要:
The invention relates to a method for treatment of wood material. In a first treatment step comprises the provision of a solution comprising zinc oxide or titanium(IV) isopropoxide and immersion of the wood material into the solution. After drying of the wood material a second treatment step is following in case of the first solution comprising zinc oxide. The second treatment step comprises the provision of a solution comprising a zinc compound and immersion of the wood material from the first treatment step into the solution followed by drying of the wood material. In a second aspect the invention relates to a wood material characterized by the visibility of the natural appearance of the surface and at least one other property relating to UV resistance, weathering resistance, mechanical resistance or hydrophobic properties.
