| Popis: | 101 In recent years, there is a lot of attention in biomaterials for organic electronics due to its biodegradable, bioresorbable, biocompatible and environmentally friendly properties. The albumen (egg white) is one kind of biomaterial. It can produce self-polymer crosslink by heating and use as a good dielectric layer. This dielectric layer can be utilized to produce organic field-effect transistor (OFET) that has a lot of applications in electronic industries. However, in the previous research, the characteristics of albumen dielectric layer (thin film) were not discussed in detail. In this study, the surface morphology and internal mechanical characteristics of albumen thin film at different heating temperatures were investigated. At 100~140℃ temperature, the hydrophilic to hydrophobic change in albumen thin film was found by using contact angle. Atomic Force Microscopy (AFM), nano-indentation and capacitance measurement were utilized to characterize the albumen thin film. However, it was found that the internal characteristic of the albumen thin film was dominant on OFET. Therefore, X-ray Diffraction (XRD) method was used to analyze the internal characteristics such as the crystallization and dimorphic characteristics of pentacene. The results showed that the hydrophilicity of the albumen thin film at different temperatures has a significant impact on the crystallization of pentacene. Furthermore, the effect of temperature on OFET process was discussed. |
