Spin coating is widely used in the preparation of thin films as it yields reproducible results with uniform surface and controlled thickness. However, free-standing thin films of polyolefins have never been produced using spin coating as the coated films do not have sufficient strength to maintain their integrity without a supporting layer or substrate. Herein, we report free-standing thin films of polyolefins such as polyethylene with varying thickness ranging from 5 to 20 μm. In one such combination, 30% porosity, 5 MPa tensile strength, and 7 μm thickness were achieved. These films can be used as hydrophobic coating, filtration membranes, and oil-sorbents.

“…Various preparation methods have been utilized to prepare the HTL of TCO thin films’ such as the spray pyrolysis method [ 12 ], the sputtering method [ 13 ], the spin coating method [ 14 ], the atomic layer deposition method [ 15 ], and other techniques. Among them, the spin coating method has great flexibility, is a simple process, has low cost, and is commercially viable [ 16 ]. Using the spin coating method, it is possible to attain a film with uniform growth, grain shape, size, and surface morphology.…”

In this research, we studied the functional properties of CuCrO2, which is the most promising p-type transparent conductive oxide (TCO). The thin films were fabricated using a spin coating technique. The diffraction patterns were obtained with the help of X-ray diffractions, and the optical properties of absorption characteristics were studied using UV-visible absorption. The physical properties of film formation and surface morphology were analyzed using FESEM analysis. The aging properties were also analyzed with the help of various precursors with different aging times. The CuCrO2 thin films’ functional properties were determined by using chelating agent and precursor solution aging times. The CuCrO2 thin films have better transmittance, resistance, figure of merit (FOM), and electrical conductivity. Moreover, the resistivity values of the CuCrO2 thin films are 7.01, 9.90, 12.54, 4.10, 2.42, and 0.35 Ω cm. The current research article covers the preparation of copper chromium delafossite thin films. These thin films can be suitable for hole transport layers in transparent optoelectronic devices.

The surface profile of the film formed by spin coating is experimentally investigated in this paper. The unavoidable wavy form at the surface was observed when the ultraviolet curable resin was used. In addition, the surface thickness variation was directly related to the viscosity, disk rotation speed, and disk size. Fluid dynamic theory with non-dimensional analysis was conducted to describe the surface profile after the spin coating process. It was found that the film had been thickened until the viscosity force and Coriolis force were balanced. The Coriolis force, however, also affected the flow instability during the spinning of the disk. The film thickness variation is successfully described by using the non-dimensional factors. In addition, the edge bump which is induced by hydraulic jump is expressed by the relation of power law of Ekman, Weber, and Reynolds numbers. In this paper, the thickness variation and edge bump position are expressed by using hydrodynamic theory. It is also reveals that the Coriolis force acts based on the magnitude of thickness variation, and the surface tension affects the edge bump position. The presented relationships will contribute further understanding of the spin coating process. The outcome of this paper supports the cost-effective productions of electronic microcircuits and solar cells.
