HDPE/Fe_3O_4纳米复合材料制备及力学性能研究

PREPARATION OF HDPE/Fe_3O_4 NANOCOMPOSITE AND ITS MECHANICAL PROPERTY STUDY

以FeCl3为前驱体,与高密度聚乙烯(HDPE)及分散剂共混后通过挤出机经原位热还原-氧化法制得HDPE/Fe3O4纳米复合材料,对其结构进行了表征,研究了FeCl3用量、分散剂种类及用量对复合材料力学性能的影响。结果表明,复合材料中Fe3O4的粒径达到纳米级,平均粒径为26nm;FeCl3的最佳用量质量分数为20%;以硬脂酸作分散剂时复合材料的综合力学性能较好。

High-density polyethylene（HDPE）/F3O4 nanocomposite was prepared by in-situ thermal deoxidizing and oxidating method through extruder with FeCl3 as the precursor. The structure of the composite was characterized, and the effects of FeCl3 and dispersant on the mechanical properties of composite were studied. The experimental results showed that nano-Fe3O4 was formed and the particle size was 26 nm on average ; the optimal dosage of FeCl3 was 20% ; the compresive mechanical properties of the composite was preferable when using stearic acid as dispersant.
