摘　　要：采用原位阴离子聚合法制备PA6／Al2O3纳米复合材料，借助广角X射线衍射（WXRD）研究其晶型结构和晶型转变．结果表明，淬冷样品均呈现单一的7晶型；在较高温度下退火2h后，Al2O3的引入更有利于基体PA6的γ晶型向α晶型转变；纯PA6的Brill转变温度在150-180℃之间，A12（）3质量分数为1．0％的PA6／Al2O3原位复合材料的Brill转变温度130-150℃之间．PA6/nano-Al2O3 nanocomposites were prepared by in-situ anionic polymerization. Wide-angle X-ray diffraction （WXRD） analysis was employed to investigate the crystal structure and Brill transition of PA6/nano-Al2O3 nanocomposites. It was found that quenched samples present γ crystal only and the introduction of nano-Al2O3 benefit the crystalline transition from 7 to a for PA6/nano-Al2O3 nanocomposites annealed at higher temperatures. The Brill temperature was between 150 ℃ and 180 ℃ for neat PA6, and was between 130℃ and 150℃ for PA6/nano-Al2O3 nanocomposites loaded with 1.0% nano-Al2O3 content.
