| 摘 要： | 内腔填充法是通过机械搅拌将Fe3O4粉末引入纤维内腔,而原位复合法是磁性纳米粒子通过化学过程形成沉淀沉积在纤维内腔中。通过X射线衍射证实了原位复合法合成出了Fe3O4磁性粒子,并成功地沉淀在纤维内腔中。扫描电镜图显示原位复合法纸张内腔中磁性粒子的尺寸和分布均优于腔内填充法纸张。样品的磁性检测结果显示内腔填充法纸张的磁性比原位复合法纸张的高,原因可认为是磁性纳米粒子拥有超顺磁性。

| Abstract: | For the lumen loading process,commercial magnetite(Fe3O4) powders have been introduced into the lumen by mixing the pulp and magnetic powder.For the in situ synthesis process,nanosized magnetite particles have been precipitated in the presence of pulp fibres and deposited inside the lumen of fibres via chemical coprecipitation process.The structure and properties of magnetic paper was characterized by using scanning electron microscope(SEM),X-ray diffraction(XRD) and vibrating sample magnetometer(VSM).The e... |
