ABSTRACT

Atomic force microscope is an equipment of choice for studying materials in atomic and nonometric scale. This paper illustrates the procedure of adhesion measurement for polymer samples using atomic force microscope.

Quantitative measurements of mechanical properties are based on the relations between cantilever responses and tip–sample interaction. These mechanical properties like adhesion and elastic modulus are measured implementing Atomic Force Spectroscopy. Recording the static deflection of the cantilever as a function of piezoelectric element displacement, force-distance curves are plotted. Hook’s law was used for converting the distances coming from the curves to force. It was necessary to calibrate the force constant of the cantilever to perform a precise force measurement.

Force-distance curves were obtained in ten different points on the surface of polymers and distance dependent measurement was conducted 10 times per each point by 1.1s interval. Adhesion force was then calculated in every single curve and the final data was the mean of one hundred different curves.
