APPLICATION AND FUNCTION OF LASER-

INDUCED BREAKDOWN SPECTROSCOPY

ON WOOD SURFACES

Wood modification with graphene oxide can give it unique features characteristic of other materials.
However, it is worth conducting an in-depth analysis of the structural changes that occur in wood
under the influence of modification with graphene oxide. Laser-assisted ionisation spectroscopy
(LIBS) was used to determine elements, and to characterise differences in the elemental composition
between the surface layers of wood impregnated with graphene oxide and native wood. Changes in
the structure of polymers building wood tissue were also analyze. By Izabela Betlej, Piotr Borysiuk,
