Design of New Generation Low-Cost Dip Coating Device and Performance Tests in ZnO Thin Film Production

In this study, a dip coating device was designed using low-cost materials and performance tests were performed. The dip coating method is an efficient coating technique used to dip samples into chemical solutions and produce thin films. The designed system provides precise movement in the vertical axis with a stepper motor, while a heating unit can be used to apply heat treatment during the coating process. The device controlled by Arduino allows the user to adjust the number of dips, waiting times and movement speed. In order to test the operation of the system, ZnO thin films were produced, and these films were evaluated with XRD, SEM and UVspectrophotometer analyses. As a result of the analyses, it was determined that the structural and optical properties of the films produced by the device were in accordance with the data in the literature. These results prove that the designed dip coating system is successful and functional.
