Polyamic Acid의 치환기 변화에 따르는 Langmuir 막의 변위전류에 관한 연구 |
| 초록 |
Displacement current measuring technique has been applied on the study of monolayers of polyamic acid containing p-nitroazobenzene(AZ-NO2) and p-cyanoazobenzene group(AZ-CN). The displacement current was generated from monolayers on the water surface by monolayer compression and expansion. Maxwell displacement current(MDC) was generated when the area per molecule was about 105Å2(AZ-NO2) and 90Å2(AZ-CN). Maxwell displacement currents were investigated in connection with monolayer compression cycles. It was found that the maximum of MDC appeared at the molecular area just before the initial rise of surface pressure in compression cycles. |
