| 제목 | Fabrication and Characterization of Aromatic Polyimide Langmuir-Blodgett Film |
| 초록 | Polyimide is a well-known organic material, which has not only high chemical and thermal stability but also good electrical insulating and mechanical properties. Langmuir-Blodgett technique is a good method to deposit the polymers as uniform film which has controlled structure and regularity. In this study, we prepared ultrathin polyimide films which have controlled thickness, defect-free and orientation by LB technique. These LB films have potential application in molecular electronic industries such as insulating layer, liquid crystal alignment and photoconductive device etc. The LB films of polyamic acid salt were fabricated using multi chain tert-amine and the film was thermally and chemically imidized. They are characterized by means of X-ray diffraction (XRD), UV-VIS spectroscopy, infrared (IR) spectroscopy and scanning electron micrograph (SEM). The d-spacing of PAAS LB film calculated from XRD is 5.31nm, which is consistent with the width of the expected bilayer structure from y-type deposition. The imidization of PAAS LB film is confirmed by IR spectroscopy. UV-VIS spectra of LB film give good relationship between the number of layers and the absorbances. The thickness and surface morphology of LB film is studied by SEM. |
