摘要：
The conjugated polycyanamide (PCN) was successfully prepared by radio frequency glow discharge techniques. The structure of PCN was characterized by means of Fourier transform infrared (FT IR) UV-Visible absorption spectra and X ray photoelectron spectroscopy (XPS) which revealed that extensive conjugation was formed in the polymer PCN. The subpicosecond time resolved optical Kerr effect (OKE) was used to measure the third order optical nonlineanty of PCN samples. For the first time an ultrafast response and nonresonant optical Kerr effect of plasma polymer PCN was observed. (C) 2002 Elsevier Science B.V. All rights reserved.
