| 英文摘要 | The cs/pva/fe3o4 nanocomposite membranes with chainlike arrangement of fe3o4 nanoparticles are prepared by a magnetic-field-assisted solution casting method. the aim of this work is to investigate the relationship between the microstructure of the magnetic anisotropic cs/pva/fe3o4 membrane and the evolved macroscopic physicochemical property. with the same doping content, the relative crystallinity of cs/pva/fe3o4-m is lower than that of cs/pva/fe3o4. the fourier transform infrared spectroscopy (ft-tr) measurements indicate that there is no chemical bonding between polymer molecule and fe3o4 nanoparticle. the fe3o4 nanoparticles in cs/pva/fe3o4 and cs/pva/fe3o4-m are wrapped by the chains of cs/pva, which is also confirmed by scanning electron microscopy (sem) and x-ray diffraction (xrd) analysis. the saturation magnetization value of cs/pva/fe3o4-m obviously increases compared with that of non-magnetic aligned membrane, meanwhile the transmittance decreases in the uv-visible region. the o-ps lifetime distribution provides information about the free-volume nanoholes present in the amorphous region. it is suggested that the microstructure of cs/pva/fe3o4 membrane can be modified in its curing process under a magnetic field, which could affect the magnetic properties and the transmittance of nanocomposite membrane. in brief, a full understanding of the relationship between the microstructure and the macroscopic property of cs/pva/fe3o4 nanocomposite plays a vital role in exploring and designing the novel multifunctional materials. |
