【摘要】 探索聚酰胺胺(PAMAM)树形分子在复合材料体系中作无机粒子表面处理剂的应用。用PAMAM树形分子对沉淀白碳黑进行表面处理,并制备SiO2/PA6复合材料;用TEM、WD-300电子万能试验机、HAKKE平板流变仪等研究了PAMAM的分子代数、用量对SiO2/PA6复合材料的微观结构、力学性能及流变性能的影响。结果表明,PAMAM树形分子能有效改善沉淀白碳黑在基质中的分散状态,提高沉淀白碳黑的增强效果,并改善复合体系的流变性能。更多还原

【Abstract】 The application of poly（amidoamine）（PAMAM） dendrimer as a surface treatment agent of inorganic particle was discussed. The micro-structure,mechanical properties and rheological properties of SiO₂/ PA6 composites with SiO₂ treated by different PAMAM generations and different PAMAM contents were investigated. It was shown that the dispersing condition of SiO₂ treated by PAMAM was improved obviously, the reinforcing action of SiO₂ was enhanced, and the rheological properties of SiO₂/PAMAM/PA6 composites were also improved.更多还原
