In this research, the elastic modules of five different types of polymers, used as soft samples, have been investigated using nanoindentation by atomic force microscopy. Initially, the elastic modulus of the polymers was obtained using the NT-MDT SOLVER P47 scanning probe microscope for both extension and retraction strokes. Considering the importance of the subject and its application in the industry. After making macropolymers, their elastic modulus and adhesion force have been obtained for both penetration and return modes of the microscope. To investigate the mechanical properties of macropolymers, a GPK atomic force microscope model, NanoWizard 3, along with its specialized software, version 0.5.96, was used. In this research, Young's modulus was expressed for all specimens using nanoindentation and tensile testing techniques. The outcomes display that a decrease in Young's modulus increases the diversity among the Young's modules resulting from nanoindentation and tensile testing techniques. By increasing the Young's modulus, the changes in the elastic modulus resulting from the extension and retraction regimes were reduced.
