Poly(acryloyl chloride) (PAC) was first reacted with oxidized MWCNT to form oxidized MWCNT-g-PAC. Then, aminated MNP were bonded to the oxidized MWCNT-g-PAC to form oxidized MWCNT-g-PAC-g-aminated MNP. The chemical characterization for primary and the product materials was performed using FT-IR spectroscopy. SEM images and SEM–EDX were used for the surface morphology and elemental characterization, respectively. Vibrating sample magnetometer measurements showed that aminated MNP and oxidized MWCNT-g-PAC-g-aminated MNP have magnetic saturation values of 52.07 emu/g and 20.38 emu/g, respectively. Both of the two samples indicated the superparamagnetic nature. TGA measurements were accomplished to compare the thermal stability of materials. Also, the DSC measurements were performed to compare T_g temperatures. While AC conductivity values of the oxidized MWCNT-g-PAC and oxidized MWCNT-g-PAC-g-aminated MNP increased by increasing frequency, it has not changed with increasing temperature. This result indicates that these materials act as electrical insulators.

Fe 3 O 4纳米粒子在聚（丙烯酰氯）功能化多壁碳纳米管表面上的化学键合

首先使聚（丙烯酰氯）（PAC）与氧化的MWCNT反应以形成氧化的MWCNT- g -PAC。然后，胺化MNP粘合到氧化MWCNT-克-PAC以形成氧化MWCNT-克-PAC-克-aminated MNP。使用FT-IR光谱对主要原料和产品原料进行化学表征。SEM图像和SEM–EDX分别用于表面形态和元素表征。振动样品磁力计测量结果表明，胺化的MNP和氧化的MWCNT- g -PAC- g胺化的MNP的磁饱和值分别为52.07 emu / g和20.38 emu / g。两个样品都表明超顺磁性。TGA测量完成以比较材料的热稳定性。另外，进行DSC测量以比较T _g温度。而AC电导率值的氧化MWCNT-克-PAC和氧化MWCNT-克-PAC-克-aminated MNP通过增加频率，它并没有随着温度的增加改变。该结果表明这些材料充当电绝缘体。
