Samples were combined under small shear paddle mixing for five minutes then permitted to relaxation in the controlled temperature and humidity area (CTH, 50% relative humidity and 70°F) right away. Equilibrium surface tension measurements have been done utilizing a Krüss K100 tensiometer plus the Wilhelmy plate process.
