A mild method of wood impregnation with biopolymers and resins using 1-ethyl-3-methylimidazolium chloride as carrier

- New, mild method of wood surface impregnation with organic biopolymers.
- Impregnants: chitosan, zein, gelatine and guaiac resin.
- Low vapour pressure solvent carrier: alkylimidazolium based ionic liquids.
- Impregnated wood has higher moisture resistance, dimensional stability and greater hardness.
- Soft wood exhibits similar or higher properties than that of hard wood.
