Abstract:
"An in situ polymerization process was used to prepare poly (methyl methacrylate) (PMMA)-functionalized carboxyl multi-walled carbon nanotubes using carboxylate carbon nanotubes and methyl methacrylate as reactants and benzoyl peroxide as an initiator agent. The functionalized multi-walled carbon nanotubes were characterized using transmission electron microscope, scanning electron microscope, nuclear magnetic resonance, Fourier transform infrared spectroscopy, thermogravimetric analysis and Raman. The results indicate that the PMMA chains are covalently linked with the surface of carboxylate carbon nanotubes. The surface morphology is controlled by the content of carboxylate carbon nanotubes in the reactants. The PMMA functionalized multi-walled carbon nanotubes are soluble in deuterated chloroform. The storage modulus and tanffi magnitude increase as the content of CCNTs increases up to 0.3%."

摘要:
"以羧基多壁碳纳米管、甲基丙烯酸甲酯作为原料,过氧化苯甲酰作为引发剂,采用原位聚合法制备聚甲基丙烯酸甲酯-功能化多壁碳纳米管.利用投射电子显微镜、扫描电子显微镜、核磁共振、傅立叶转换红外光谱,热重分析和拉曼光谱对合成产物进行分析表征.结果表明,聚甲基丙烯酸甲酯共价接枝到羧基碳纳米管表面,羧基碳纳米管的含量影响合成产物的表观形态.核磁共振研究表明聚甲基丙烯酸甲酯-功能化多壁碳纳米管在氘代氯仿中有一定的溶解性."
