in the context of the polymer film on an aqueous transfer process, A high value of spreading coefficient(S) is key to improving the polymer film uniformity and crystalline structure, which affect the organic field-effect transistor(OFET) device performance. In addition, solidified orientations are different depending on the direction in which the film is transferred. The differences between the upward(UST) and downward(BST) confirmed that the solvent in the polymer solution droplet was rapidly extracted at the interface with the base media and was slowly evaporated near the air interface with the polymer solution. The results induce rapid solidification with poor structural properties at the base media interface and slow solidification with good structural properties at the air interface. The surface properties of films were advantageous in the vicinity of the air/polymer solution interfaces for use as a channel active layer, resulting in good OFET device performances for the UST case. |
