The polymer was well characterized. Its Tg was tested to be 168℃, and the poled film of P2 reveals a resonant d33 value of 20 pm/V by second harmonic generation ( SHG ) measurements.展开更多
A new intercalation compound, Fe0.85PS3(4,4-bipyH)0.30 (4,4-bipy = 4,4-bipyridine), is obtained by the intercalation of 4,4-bipyridine?HCl with lamellar FePS3, which is characterized by elemental analysis, powder X-r...A new intercalation compound, Fe0.85PS3(4,4-bipyH)0.30 (4,4-bipy = 4,4-bipyridine), is obtained by the intercalation of 4,4-bipyridine?HCl with lamellar FePS3, which is characterized by elemental analysis, powder X-ray diffraction, infrared spectroscopy. By comparison with the pure FePS3, the lattice spacing of Fe0.85PS3(4,4-bipyH)0.30 is expanded by ~ 5.7 , indicating that the ring plane of the guest is perpendicular to the layer of the host. The magnetic property of Fe0.85PS3(4,4-bipyH)0.30 is studied with SQUID. It exhibits an antiferromagnetic phase transition with TN of about 70 K.展开更多
