Synthesis and failure behavior of super-aligned carbon nanotube film wrapped graphene fibers,Carbon 72 (2014) 250-256. 影響因子:6.16 摘要:Significant progress has been made in recent years in research on wet spinning and hydrothermal synthesis of graphene fibers. In this paper, we report the relationship between the mechanical performance of graphene oxide (GO) fibers and their processing parameters in wet spinning. With super-aligned carbon nanotube (CNT) film wrapping, the specific strength and electrical conductivity of reduced GO (rGO) fibers were simultaneously enhanced by 22% and 49%, respectively. Thicker CNT filmwrapping of the rGO fiber induces a core–sheath structure; the resulting interfacial debonding and slippage under fiber axial loading were examined. The findings of this study provide guidelines for optimization of high-performance graphene/CNT hybrid fibers. 中文翻譯摘要:最近幾年在石墨烯纖維的濕紡和水熱合成研究領(lǐng)域已經(jīng)取得了很大進(jìn)步。在該文章中,報(bào)道了在濕紡中氧化石墨烯纖維的機(jī)械性能和它們的工藝參數(shù)之間的關(guān)系。用超整齊的碳納米管(CNT)薄膜包裹,還原的氧化石墨烯纖維的比強(qiáng)度和導(dǎo)電率分別同時(shí)提高了22%和49%。還原的氧化石墨烯纖維的厚CNT薄膜包裹材料引起核心的保護(hù)結(jié)構(gòu);觀察了在纖維軸向的負(fù)載產(chǎn)生的界面脫粘和滑移。這項(xiàng)研究為優(yōu)化高性能的石墨烯/CNT混合纖維提供了方向。 想獲得更多資源可點(diǎn)擊鏈接http://www.tjdrfk.com/news 圖片4.jpg 圖片1.jpg 圖片2.jpg 圖片3.jpg |
