The new wood-plastic nanocomposites (WPC) based on acrylonitrile-butadiene-styrene (ABS) resin was successfully blended with ABS and poplar flour (PF) through a HAAKE rheomix. The mechanical properties of nanocomposites, except for flexural modulus, were reduced after increasing the PF content. SEM photos show the reduction resulting from weak interfacial adhesion between the PF phase and ABS phase. Higher PF content leads to a low thermal stability and a high water absorption ratio. Different coupling agents (CA) were employed to improve the compatibility between PF and ABS. The results suggest that ABS-g-MAH is more effective than POE-g-MAH, EVA and SEBS. Maleic anhydride (MA) was blended with PF and ABS as the reactive compatibilizer and mechanical properties of nanocomposites were improved except impact strength.
基于丙烯腈-丁二烯-苯乙烯（ABS）树脂的新型木塑纳米复合材料（WPC）通过哈克流变混合器成功地与ABS和杨木粉（PF）共混。增加PF含量后，纳米复合材料的机械性能（除弯曲模量外）均有所降低。扫描电子显微镜照片显示，这种降低是由于PF相和ABS相之间的界面粘附力较弱所致。较高的PF含量导致热稳定性较低和吸水率较高。使用了不同的偶联剂（CA）来改善PF和ABS之间的相容性。结果表明，ABS-g-MAH比POE-g-MAH、EVA和SEBS更有效。将马来酸酐（MA）与PF和ABS共混作为反应性增容剂，纳米复合材料的机械性能得到改善，但冲击强度除外。
