本文研究了纳米粒子对茂金属聚乙烯/木纤维纳米复合材料在化学发泡剂作用下挤出发泡过程中泡孔形态和发泡性能的影响。结果表明，粘土的加入通常会减小泡孔尺寸，增加泡孔密度，并促进泡沫膨胀。此外，添加有粘土的泡沫材料在燃烧时显示出良好的成炭。
This article investigates the effects of nanoparticles on cell morphology and foam expansion in the extrusion foaming of metallocene polyethylene/wood fiber nanocomposites with a chemical blowing agent. The results indicate that the addition of clay generally reduces the cell size, increases the cell density, and facilitates foam expansion. Furthermore, the foam material with added clay shows good char formation when it is burned.
