Technical Field

Background
The mechanical property of the polymer film has important significance in daily use, and the basic method for researching the mechanical property is to adopt a stretching device to stretch a film material to obtain the mechanical parameters of the material. The mechanical properties of polymer materials commonly used in laboratories, such as the Shimadzu tensile tester of Shimadzu, Japan, are obtained by uniaxial tension (one end is fixed and the other end is stretched). The conventional stretching device such as an Shimadzu stretching tester has large volume and wide occupation, cannot be used with various in-situ detection devices and can detect the change of the microstructure of the stretching (compressing) process in situ on line, and is not suitable to be used as a tool for theoretically researching the stretching deformation mechanism. Different areas of the sample move all the time in the uniaxial stretching process, so that the position of a research area (light spot) cannot be accurately positioned, and the obtained result has errors compared with a real result.
