Besides polyamide 11 (PA 11) outstanding properties, wear performance is considered a key factor for its continued widespread use. TiTanate NanoTubes (TTNT) have a huge potential as reinforcement in polymer matrix nanocomposites, and although nanotubes reinforcement capacity is well understood, its effect on tribological characteristics is still an open question. Thus, the present work has as objective to study the wear behavior of PA 11 and its nanocomposites, highlighting TTNT loading, functionalization and sodium content effects. Seeking the possibility to tailor properties, surface topography is investigated. Based on parameter classification, correlation and functional sense, an ideal roughness parameter set is defined. By taking measurements in X- and Y-axis, parameter variations and sensibility are also analyzed. From the results, maximum wear resistance can be reached in functionalized samples with low TTNT loading and high sodium content. Some roughness parameters demonstrate a moderate to strong correlation with wear performance. Parameter variations are mainly attributed to the non-stationarity of the surface.

除了聚酰胺11（PA 11）优异的性能外，耐磨性能还被认为是其继续广泛使用的关键因素。TiTanate NanoTubes（TTNT）在聚合物基质纳米复合材料中具有巨大的增强潜力，尽管人们对纳米管的增强能力已广为人知，但其对摩擦学特性的影响仍然是一个悬而未决的问题。因此，目前的工作以研究PA 11及其纳米复合材料的磨损行为为目标，突出了TTNT的负载，功能化和钠含量的影响。为了寻找调整特性的可能性，对表面形貌进行了研究。基于参数分类，相关性和功能意义，定义了理想的粗糙度参数集。通过在X轴和Y轴上进行测量，还可以分析参数变化和灵敏度。从结果来看 在低TTNT含量和高钠含量的功能化样品中，可以达到最大的耐磨性。一些粗糙度参数显示出与磨损性能之间的中等至强相关性。参数变化主要归因于表面的非平稳性。
