| Description | Journal: Chinese Physics B The $CS/PVA/Fe_{3}O_{4}$ nanocomposite membranes with chainlike arrangement of $Fe_{3}O_{4}$ 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 $CS/PVA/Fe_{3}O_{4}$ membrane and the evolved macroscopic physicochemical property. With the same doping content, the relative crystallinity of $CS/PVA/Fe_{3}O_{4}$-M is lower than that of $CS/PVA/Fe_{3}O_{4}$. The Fourier transform infrared spectroscopy (FT-TR) measurements indicate that there is no chemical bonding between polymer molecule and $Fe_{3}O_{4}$ nanoparticle. The $Fe_{3}O_{4}$ nanoparticles in $CS/PVA/Fe_{3}O_{4}$ and $CS/PVA/Fe_{3}O_{4}$-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 $CS/PVA/Fe_{3}O_{4}$-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 $CS/PVA/Fe_{3}O_{4}$ 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 $CS/PVA/Fe_{3}O_{4}$ nanocomposite plays a vital role in exploring and designing the novel multifunctional materials. |
