摘要
以MgCl2.6H2O和NH3.H2O为原料,首先通过溶剂热合成纤维状的Mg2(OH)3Cl.3H2O前驱物,采取前驱物分解方法制备氧化镁晶须。利用SEM和XRD对产物进行了表征。结果表明:未加有机溶剂合成的晶须直径较小,且粗细不均;添加有机溶剂后晶须直径变大,粗细比较均匀,分散性也好,较佳的合成条件是添加乙醇和异丙醇混合溶剂。用氧化镁晶须改性聚丙烯,探讨晶须含量对复合材料力学性能的影响,结果表明:当晶须添加量为20%时,复合材料力学性能最佳。
Using MgCl2 · 6H2O and NH3 · H2O as raw material , Mg2 （OH）3Cl·3H2O whisker was synthesized by solvothermal method, then magnesium oxide was obtained by decomposed of Mg2 （OH）3Cl·3H2O. The products were characterized by SEM and XRD. The results showed that the diameter of magnesium oxide whisker was samller and uneven without organic solvent in the process of synthesis, while the diameter of magnesium oxide whisker was bigger and even with organic solvent. The better condition was using alcohol and isopropyl alcohol as solvent. Then the composite of whisker and polypropylene had been made. The effects of whisker content on mechanical properties of composite were studied. The results showed that the mechanical properties of composite were the best when the whiskers content was 20 %.
