采用可接近定向自组装法制备了纳米纤维素/聚磷酸铵（NCC/APP）聚电解质复合物（佩奇），并利用透射电镜、扫描电镜、傅立叶红外光谱和X射线衍射对其形貌和超微结构进行了研究。采用热重分析、锥形量热分析、极限氧指数（LOI）和力学性能测试等方法，研究了制备的佩奇作为稻草-HDPE复合材料（RPC）的阻燃体系的热降解、阻燃性能和力学性能。佩奇的加入对RPC的热稳定性和阻燃性能有显著影响。佩奇能促进RPC的早期热降解，稳定残炭。佩奇能显著提高RPC的氧指数，NCC 1/APP和NCC 5/APP的氧指数分别提高到24.8%和25.0%，佩奇对RPC的热释放速率影响不大。NCC/APP复合体系中的佩奇也能改善RPC的力学性能，其拉伸强度和弯曲强度均有所提高。
Polyelectrolyte complexes (PECs) with nanocrystalline cellulose and ammonium polyphosphate (NCC/APP) were prepared by an accessibly oriented self-assembly method, and the morphology and ultrastructure were investigated with transmission electron micrographs, scanning electric microscopy, Fourier infrared, and X-ray diffraction. The prepared PECs were then used as a flame-retardant system in rice straw-HDPE composites (RPC), and the thermal degradation, flame retardancy, and mechanical properties were studied by thermogravimetry, cone calorimetry, limited oxygen index (LOI) and mechanical testing. The thermal stability and flame retardancy of RPC were significantly influenced with an incorporation of PECs. PECs can promote the thermal degradation of RPC that take place earlier and stabilize the char residues. PECs can significantly improve the LOI of RPC, and LOI increased to 24.8% and 25.0% in the presence of NCC1/APP and NCC5/APP. PECs had a slight effect on heat release rate. PECs can also improve the mechanical property of RPC, and the tensile and flexural strength were increased with the addition of PECs of NCC/APP.
