Abstract
Determination of surface free energy of selected tropical wood species from Africa In this study surface free energy selected tropical wood species was determined. The aim of this paper was to compare surface properties selected wood species from Africa using contact angle measurements. Selected for the tests wood species are popular material in Europe for floors and other elements of interiors equipment. During the research, basic anatomical cross sections – radial and tangential (as the most dominant in finished products) were analyzed separately. Parallel, the European wood species - Fagus sylvatica L., Pinus sylvestris L. and Quercus petraea (Matt.) Liebl. - were also tested for comparison. It was found that there is no significant difference between radial and tangential cross section in case of every tested wood species and wood structure has influence on properties of wood surfaces. Heartwood of tested European wood species is characterized by lower value of surface free energy than sapwood.
