Polynomial functions for direct calculation of the surface free energy developed from the Neumann Equation of State method

Jonathan M. Schuster, Carlos E. Schvezov, Mario R. Rosenberger

The Neumann Equation of State (EQS) allows obtaining the value of the surface free energy of a solid ${\gamma }_{SV}$ from the contact angle $(\theta )$ of a probe liquid with known surface tens…
