摘要:
采用溶剂热法制备磁性四氧化三铁(Fe3O4)纳米粒子,随后利用改进的溶胶凝胶法制备四氧化三铁与二氧化硅复合纳米粒子(Fe3O4@SiO2),再以聚乳酸(PLA)为基体,通过熔融共混工艺制备Fe3O4@SiO2/PLA共混材料。采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、差示扫描量热仪(DSC)、万能拉伸试验机、熔体流动速率仪(MFR)和振动样品磁强计(VSM)等对共混材料的形貌、结晶结构、热性能、力学性能、熔体流动速率和磁性能进行表征分析。结果表明:添加量为1%(以质量分数计)的Fe3O4@SiO2纳米粒子可在PLA基体中均匀分散,与基体有良好的界面相容性。相比于纯PLA,Fe3O4@SiO2/PLA共混材料的热性能变化不大,当Fe3O4@SiO2的添加量为1%时,共混材料的结晶度最大。随着Fe3O4@SiO2质量分数的增加,共混材料的拉伸强度呈先增加后下降的趋势,而断裂伸长率没有明显变化。在同一温度下,Fe3O4@SiO2/PLA共混材料的熔体流动速率明显增加,熔融指数大于150 g/(10 min),流动性较好,能满足熔喷加工可纺性的要求。另外,Fe3O4@SiO2/PLA共混材料的饱和磁化强度会随着Fe3O4@SiO2质量分数的增加逐渐增加。研究结果可为开发熔喷非织造布用磁性Fe3O4@SiO2/PLA共混材料提供理论依据。
