论文摘要
基于聚（三甲基三甲酸链苯甲酸酯 - 氧化二甲苯氧化物）共聚物（PTT-PTMO）和氧化石墨烯-FE3O4纳米粒子杂交的热塑性弹性弹性纳米复合材料，由杂种及其杂种及其杂种及其杂种杂种制备。 X射线光谱光谱（XP），X射线衍射（XRD），热重分析（TGA）和扫描电子显微镜（SEM）的效果（0.3和0.5 wt％）。纳米复合材料通过差分扫描量热法（DSC）和动态机械热分析（DMTA）（DMTA）在弹性基质中的GO-FE3O4纳米颗粒的分散率。鱿鱼磁化测量与温度（从2到300 K）以及在微波频率下的外部磁场和铁磁共振（FMR）的函数。
Thermoplastic elastomeric nanocomposites based on poly(trimethylene terephthalate-block-poly(tetramethylene oxide) copolymer (PTT-PTMO) and graphene oxide-Fe3O4 nanoparticle hybrid were prepared by in situ polymerization. Superparamagnetic GO-Fe3O4 hybrid nanoparticles before introducing to elastomeric matrix were characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The effect of loading (0.3 and 0.5 wt%) of GO-Fe3O4 nanoparticle hybrid on the phase structure, tensile and magnetic properties of synthesized nanocomposites was investigated. The phase structure of nanocomposites was evaluated by differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA). Dispersion of GO-Fe3O4 nanoparticles in elastomeric matrix was evaluated by transmission electron microscopy (TEM). Magnetic properties of GO-Fe3O4 nanoparticle hybrid and nanocomposites with their content were characterized by using two different techniques: dc SQUID magnetization measurements as a function of temperature (from 2 to 300 K) and external magnetic field and ferromagnetic resonance (FMR) at microwave frequency.
