Abstract Graphyne and graphdiyne nanofillers (nanoplatelets and nanotubes), are embedded in Aluminum matrices originating graphyne and graphdiyne/Al nanocomposites. Pristine Al and the nanocomposites are melted and then recrystallized at a fixed colling rate, 1 K/ps. Al nanocomposites with planar nanofillers show a 46–53% increase in nucleation temperature and 78–88% recrystallization yield while Al nanocomposites with tubular nanofillers present a 16–32% increase in nucleation temperature and a 65–75% recrystallization yield. Al nanocomposites with planar nanofillers present a 26–36% increase in the Young's modulus, while Al nanocomposites with tubular nanofillers show a 23–31% increase in the Young's modulus. The improved mechanical properties of graphyne and graphdiyne/Al nanocomposites depend on i) the elasticity and shape (planar vs tubular) of the nanofillers ii) the level of recrystallization of the Al matrix and iii) the interfacial adhesion in the interface between the nanofillers and the Al matrix. Graphyne pore size positively affects interfacial adhesion.

γ-石墨烯增强铝复合材料：纳米填料孔隙率和形状对晶体生长和复合材料强化的影响

摘要 石墨炔和石墨二炔纳米填料（纳米片和纳米管）嵌入铝基质中，形成石墨炔和石墨二炔/铝纳米复合材料。原始铝和纳米复合材料熔化，然后以固定的冷却速率 1 K/ps 重结晶。具有平面纳米填料的铝纳米复合材料的成核温度提高了 46-53%，再结晶产率提高了 78-88%，而管状纳米填料的铝纳米复合材料的成核温度提高了 16-32%，再结晶产率提高了 65-75%。具有平面纳米填料的铝纳米复合材料的杨氏模量增加了 26-36%，而具有管状纳米填料的铝纳米复合材料的杨氏模量增加了 23-31%。石墨炔和石墨炔/铝纳米复合材料改善的机械性能取决于 i) 纳米填料的弹性和形状 (平面与管状) ii) 铝基体的再结晶水平和 iii) 纳米填料和Al 矩阵。石墨烯孔径对界面粘附有积极影响。
