Abstract

The features of the shape and distribution of graphene flakes in the Al2O3/G nanocomposite based on corundum nanoceramics obtained using spark plasma sintering technology have been studied. Scanning and transmission electron microscopy have shown the diversity of graphene morphology at the boundaries and inside grains, in the form of agglomerates and bridges, oriented and chaotic lamellar structures. It is shown that the addition of graphene leads to the appearance of shear bands in brittle ceramics, indicating intragranular deformation.

石墨烯在Al2O3/G纳米复合材料中的形态特征
研究了用火花等离子烧结技术制备的刚玉纳米陶瓷Al2O3/G纳米复合材料中石墨烯薄片的形状和分布特征。扫描电镜和透射电镜显示了石墨烯在晶界和晶粒内部形态的多样性,有团块和桥的形式,有取向的和混沌的片层结构。结果表明,石墨烯的加入导致脆性陶瓷中出现剪切带,表明晶内变形。
