Abstract
The force of adhesion between crossed carbon filaments submerged in an aqueous buffer solution has been measured. The decrease of this force, observed on addition of surfactants (cetyltrimethyl ammonium bromide or decylsulphonic acid) to the solution, is in agreement with that predicted by the thermodynamic theory of adhesion (B. V. Deryagin, Koll. Z. 69, 155 (1934)). A relation between the force of adhesion between the filaments and their wetting properties was derived and is supported by the experiments. It is concluded that adhesion in the above systems can be described by thermodynamics.Keywords
