通过在聚合物基体中添加纳米填料制备高性能和具有多种功能性聚合物基纳米复合材料是扩大其应用范围的有效手段。利用呋喃基团与单壁碳纳米管（SWNTs）在温和条件下的Diels-Alder反应制备了侧链含呋喃基团的芳香族聚酰胺（fPA）和SWNTs可逆交联复合材料（SWNTs/fPA）。结果表明，添加质量分数为0.6%的SWNTs就能显著改善fPA的机械性能。SWNTs/fPA复合材料具有良好的循环加工性能，并且SWNTs的加入改善了fPA的形状记忆性能。

Preparation of high performance and multi-functional polymer-based composites by adding nanofillers as reinforcing phase into polymer matrix is an effective way to expand its application scope.A reversibly cross-linked composites consisted of aromatic polyamide (fPA) and single walled carbon nanotubes (SWNTs) is prepared through Diels-Alder (D-A) reaction under mild conditions with pendent furan groups and SWNTs as raw materials.It is indicated that the addition of 0.6 wt% SWNTs can greatly improve fPA's mechanical and thermal properties.SWNTs/fPA composites have good reprocessing properties and better shape memory performance.
