概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
AIM: To know the height of the polymer film. Use: A height profile image for various polymer films
実験 / Experimental
Exp: We deposit a drop of 2 mm diameter polymer on the glass substrate and let it dry overnight. Then, the dried film is used under this microscope to scene the 3d height profile.
結果と考察 / Results and Discussion
Height profile maps for polymer films provide valuable insights into the surface topography and morphology of the films as shown in Fig. 1 and Fig.2. The changes in processing parameters, such as concentration, affect the morphology of polymer films, thereby influencing crack formation behavior. Height profile maps obtained from films This elucidates the relationship between processing parameters and crack formation. The Height profile maps are correlated with mechanical properties data that is obtained by optical microscopy as the dynamics of the crack propagation. This correlation enables us to understand how variations in surface morphology relate to the film's mechanical behavior, including its resistance to crack initiation and propagation. Overall, height profile maps play a crucial role in gaining the underlying mechanisms governing crack formation in polymer films, as these serve as a fingerprint of the healthy and non-healthy samples. This helps us to design a pattern recognized tool for various bio-medical applications.
