A facile approach was developed to prepare multi-walled carbon nanotubes/graphene nanoplatelets hybrid materials through covalent bond formation. First, poly(acryloyl chloride) was grafted onto oxidized multi-walled carbon nanotubes through the reaction between the acyl chloride groups of poly and the hydroxyl groups of oxidized multi-walled carbon nanotubes. Second, the remaining acyl chloride groups of poly were allowed to react with the hydroxyl groups of hydroxylated graphene nanoplatelets. Scanning electron microscopy and transmission electron microscopy data showed that the multi-walled carbon nanotubes and graphene nanoplatelets were effectively connected with each other. And Fourier transform infrared spectroscopy data indicated the formation of covalent bonds between carbon nanotubes and graphene nanoplatelets. Conformational changes were monitored by Raman spectroscopy. This novel kind of carbon hybrid materials may have the potential application in a wide field, especially in increasing the toughness and strength of the matrix resin.
通过共价键形成，开发了一种将多壁碳纳米管/石墨烯纳米片混合材料制备的简易方法。首先，通过多酰氯基团与氧化多壁碳纳米管上的羟基之间的反应，将聚（丙烯酰氯）接枝到氧化多壁碳纳米管上。其次，允许多上剩余的酰氯基团与羟基化石墨烯纳米片的羟基反应。扫描电子显微镜和透射电子显微镜数据表明，多壁碳纳米管和石墨烯纳米片有效地相互连接。傅里叶变换红外光谱数据表明了碳纳米管和石墨烯纳米片之间共价键的形成。通过拉曼光谱监测构象变化。这种新型碳混合材料可能具有广泛的应用潜力，特别是在提高基体树脂的韧性和强度方面。
