摘要：采用水热法制备了一维材料 ZnO 和 MoO 3 纳米线（nanowires，NWs），并通过 SEM 和 XRD 对纳米线的
形貌和结构进行了表征。将一维纳米线和纳米氢氧化铝（ ATH ）与聚丙烯（ PP ）熔 融共混制备了
ZnO/MoO 3 /Al(OH) 3 /PP 复合材料(NWs/ATH/PP)。利用 TGA、极限氧指数（LOI）测定仪和锥形量热仪（CCT）
表征了复合材料的热稳定性和燃烧性能，利用万能材料试验机测试了复合材料的力学性能。结果表明：当添加
质量分数 3.75% ZnO 纳米线、质量分数 3.25% MoO 3 纳米线和质量分数 21.00%纳米 ATH 时，NWs/ATH/PP 复合
材料的初始分解温度较纯 PP 增加了 17.8 ℃，残重率为 24.6%，峰值热释放速率（PHRR）和总热释放量（THR）
分别下降了 54.3%和 25.7%，LOI 提高 7.1%。SEM 结果显示：NWs/ATH/PP 的残炭表面致密、连续且平整。

Abstract: One-dimensional materials of ZnO and MoO 3 nanowires (NWs) were prepared via hydrothermal
method. Their morphology and structure were characterized by SEM and XRD. A series of ZnO/MoO 3/
Al(OH) 3/polypropylene (PP) composites (NWs/ATH/PP) were prepared by melt blending one-dimensional
nanowires and nano-aluminum hydroxide (ATH) with PP. The thermal stability and combustion properties
of the composites were characterized by TGA, limiting oxygen index (LOI) analyzer and cone calorimeter
(CCT). The mechanical properties of the composites were tested by universal testing machine. The results
showed that when the adding amounts of ZnO nanowires, MoO 3 nanowires and nano-ATH were 3.75%,
3.25% and 21.00% (mass fraction), respectively, the initial decomposition temperature of the prepared
NWs/ATH/PP composites was 17.8 ℃ higher than that of pure PP, and the residue rate was 24.6%. And
the peak heat release rate (PHRR) and total heat release (THR) were decreased by 54.3% and 25.7%,
respectively. The LOI value was increased by 7.1%. The results of SEM analysis showed that the surface of
residual char of NWs/ATH/PP composites was well improved, dense, continuous and flat.
