摘要
采用化学共沉淀法经过硅烷偶联剂改性制备纳米四氧化三铁粒子(纳米Fe3O4),再通过不同的制备工艺与天然胶乳(NR)共混,制备纳米Fe3O4/天然橡胶复合材料(纳米Fe3O4/NR)。利用马尔文MS2000激光粒度仪、X射线衍射仪(XRD)和扫描电子显微镜(SEM)等分析仪器分别对所制备样品的形貌、成分及结构进行表征。结果表明:化学共沉淀法制备的纳米Fe3O4粒子为结晶态,粒径约为47nm。硅烷偶联剂可有效地对纳米Fe3O4表面进行改性;改性后的纳米Fe3O4粒子,增强了纳米Fe3O4/NR复合材料的界面作用,提高了纳米Fe3O4粒子在NR中的分散性,改善了复合材料的结构和性能。
Fe3O4 nanoparticles （nano-F3O4 ）, which was blend with natural rubber latex with the help of various preparation technology to prepare nano-Fe3O4/natural rubber composites （nano-Fe3O4/NR）, was modified by the silane coupling agent through the chemical co-precipitation method. The morphology, structure and composition of the samples were characterized by Malven Laser Mastersizer 2000 Particle Size Analyzer,X-ray powder diffraction （XRD）, scanning e- lectron microscope （SEM） and the other analytical instruments, respectively. The results demonstrated that nanoparticles were crystal state and the average size of the particles was about 47nm. The surface of nanoparticles could be effectively modified by silane coupling agent. The interfacial interaction and the dispersion of the composites was enhanced, result to improve the structure and the mechanical properties of the composites with the incorporation of nanoDarticles.
