【摘要】：采用氧化多壁碳納米管(O-MWCNTs)和四氧化三鐵改性氧化多壁碳納米管(Fe_3O_4/O-MWCNTs)對環(huán)氧樹脂(EP)進行修飾,研究了改性O(shè)-MWCNTs對EP基體熱膨脹系數(shù)(CTE)的影響。結(jié)果表明:改性O(shè)-MWCNTs由于其表面的官能團可與EP基體形成共價鍵,從而增強了二者之間的界面作用力。相對于純EP,O-MWCNTs和Fe_3O_4/O-MWCNTs改性EP的玻璃化轉(zhuǎn)變溫度(T_g)分別升高了4.77和6.15℃;兩種改性EP在T_g之下的CTE值分別降低了32.7%和41.8%,而T_g之上的CTE值均高于純EP。
[Abstract]:Epoxy resin (EP) was modified by oxidized multiwalled carbon nanotubes (O-MWCNTs) and Fe _ 3O _ 4 / O-MWCNTs (Fe3O _ 4 / O-MWCNTs). The effect of modified O-MWCNTs on the thermal expansion coefficient (CTE) of EP matrix was studied. The results show that the functional groups on the surface of the modified O-MWCNTs can form covalent bonds with the EP matrix, thus enhancing the interfacial force between the modified O-MWCNTs and the modified O-MWCNTs. Compared with pure EPN O-MWCNTs and Fe3O- modified EP, the glass transition temperature (TSP) of the modified EP increased by 4.77 鈩，
