The effect of gamma irradiation on neat Polyamide-11 (PA11) and PA11 filled with 3 wt% of halloysite nanotubes (HNTs) was investigated at various doses up to 100 kGy in air and at room temperature. The irradiation test was conducted on sample films prepared by a twin-screw extruder in the first step then cast extrusion. The study showed the formation of a maximum of gel fraction up to 10 and 20 kGy for neat PA11 and PA11/HNTs, respectively. Furthermore, the results indicated the occurrence of crosslinking at low irradiation dose, whereas chain scission took place at higher ones. Additionally, the results revealed that the presence of HNTs limits the impacts of gamma irradiation through a barrier effect. An optimum irradiation dose was found for thermal and mechanical properties, corresponding to the dose for maximum gel formation. Moreover, experimental design was implemented to highlight the main incidences and interactions of both halloysite incorporation and radiation dose on some relevant effects of gamma irradiation.

在空气和室温下，以高达 100 kGy 的各种剂量研究了伽马辐射对纯聚酰胺 11 (PA11) 和填充了 3 wt% 埃洛石纳米管 (HNT) 的 PA11 的影响。辐照试验是在第一步用双螺杆挤出机然后流延挤出制备的样品薄膜上进行的。研究表明，对于纯 PA11 和 PA11/HNT，分别形成了高达 10 kGy 和 20 kGy 的最大凝胶分数。此外，结果表明在低辐射剂量下发生交联，而在较高剂量下发生断链。此外，结果表明，HNT 的存在通过屏障效应限制了伽马辐射的影响。发现了热性能和机械性能的最佳照射剂量，对应于最大凝胶形成的剂量。而且，
