Ângulo de Contato e Rugosidade de Madeiras, uma breve revisão.

- Abstract
This review discusses the wettability of wood surfaces through the contact angle, which in turn qualifies the wettability and can provide free energy, or surface tension. The sessile drop method is discussed for its simplicity and relative accuracy to measure the contact angle. Although the wood is characterized as a highly anisotropic and heterogeneous material, it is possible to verify the contact angle and to assimilate the result with other variables of the wood surface, such as the amount of extractives and lignin, the surface roughness and type of the wood, earlywood or latewood. Treatments common to wood also influence the contact angle and its wettability, since there is a clear relationship between the sanding and the roughness as well as the effects that sanding causes on the contact angle.
