PE-g-SWCNTs材料结晶与力学性能的研究

Study on Crystallinity and Mechanical Properties of PE-g-SWCNTs Nanocomposites

利用共聚合法来制备单壁碳纳米管接枝聚乙烯(PE)纳米复合材料(PE-g-SWCNTs),在参加反应时能够改善SWCNTs在基体中的分散,同时将PE链接枝到SWCNTs表面上,也能够增强两界面作用力。考察PE-g-SWCNTs纳米复合材料的结晶性能和力学性能的同时,从材料的结构和结晶结构等方面解释了力学性能提高的可能原因。

A copolymerization method was used to synthesize polyethylene （PE） chains grafted onto the sidewalls of SWCNTs （PE-g-SWCNT）. The dispersion of the SWCNTs in PE matrix was improved. PE chains were successfully grafted onto the surface of SWCNTs which can also increase the interracial strength between the two components. The crystallinity and mechanical performance of the PE-g-SWCNT nanocomposites was investigated. The reasons for the improvements in mechanical properties were attributed to the structure and the crystallinity structure of the nanocomposites.
