Orientation in conjugated polymers is a unique phenomenon by the virtue of their one dimensionality leading to semiconductor performances in organic electronic devices. A unique, cost-effective and highly efficient method for the fabrication of oriented thin film consisted of non-regiocontrolled poly(3-hexylthiophene) (NR-P3HT) using dynamic floating-film transfer method (dynamic-FTM) hasbeen investigated. Orientation of NR-P3HT by dynamic-FTM has been quantitatively measured as the optical anisotropy represented by dichroic ratio (DR). Amongst several factors like concentration of polymer solution, temperature and viscosity ofliquid-substrate along with post-annealing temperature, viscosity of liquid-substrate plays a crucial role in controlling the molecular orientation. A judicious control and optimization of various underlying factors affecting the molecular orientation led to relatively high DR of 9.3 even in NR-P3HT films cast by dynamic-FTM.
