碳纳米管在聚烯烃材料中的掺杂改性研究

Research on Doping Modification of Carbon Nanotubes in Polyolefin Materials

聚烯烃材料中聚丙烯、聚乙烯是一类应用广泛的聚合物,在实际应用中部分性能欠佳,需要进一步掺杂改性。碳纳米管是一种综合性能优异,且适用于聚烯烃材料的掺杂改性。本文以碳纳米管为主要改性材料,简述了碳纳米管的相关理化性质和制备方法,分析论述了碳纳米管与聚烯烃材料的共混方式,重点分析了碳纳米管对聚烯烃材料的掺杂改性。

Among polyolefin materials,polypropylene and polyethylene are widely used polymers,but some of their properties are not good in practical application,so they need to be further modified.Carbon nano⁃tubes(CNTs)have excellent comprehensive properties and are suitable for doping modification of polyolefin materials.Taking CNTs as the main modification material,in this paper,the physicochemical properties and preparation methods of CNTs are briefly described,and the blending method of CNTs and polyolefin materi⁃als is analyzed,and the doping modification of polyolefin materials by CNTs is analyzed emphatically.
