原位聚合制备尼龙610/改性蒙脱土纳米复合材料的研究

Research on Nylon 610/Modified Montmorillonite Nanocomposites Prepared by In-Situ Polymerization

采用增塑剂N-甲基苯磺酰胺对蒙脱土(MMT)进行改性,通过原位聚合法制备了尼龙(PA)610/改性MMT纳米复合材料。研究了改性MMT用量对PA610/改性MMT纳米复合材料性能的影响。结果表明,当改性MMT的质量分数为4%时,纳米复合材料的冲击强度和拉伸强度达到最大值,断裂伸长率则随着改性MMT用量的增加而降低。扫描电子显微镜观察发现,改性MMT均匀分散在PA610基体中。

Montmorillonite （MMT） was modified by using the plasticizer of N-methyl benzene sulfonamide, and then nylon （PA）610 / modified MMT nanocomposites were prepared by in-situ polymerization, The effects of modified MMT content on the properties of PA610 /modified MMT nanocomposites were studied. The results show that when the mass fraction of modified MMT is 4%, the impact strength and tensile strength of the nanocomposites reach maximum. Moreover, the elongation at break of the nanocomposites decrease with the increase of modified MMT content. The observation results of scanning electron microscopy show that the modified MMT disperse uniformly in the PA610 matrix.
