Floating film transfer method for the fabrication of semiconducting polymer-based organic thin film transistor: A mini review

In recent years, the Floating Film Transfer Method (FTM) has gained attention as an innovative approach for fabricating organic thin-film transistors (OTFTs) using organic conjugated polymers. This innovative solution-processing technology provides advantages for the orientation of macroscopic conjugated polymers along with being straightforward processes with encouraging outcomes. Here, we review the recent research on this technology, covering the process mechanism and key variables that affect the mobility of organic thin-film transistors fabricated using this novel method. This review also addresses the ability of FTM to produce uniform thin films of semiconducting polymers on hydrophilic substrates. The review concludes by discussing the limitations and challenges of the FTM.
