石墨烯材料以其優(yōu)異的本征力學(xué)性能,被認(rèn)為是新一代金屬基復(fù)合材料中理想的增強(qiáng)體。特別是,由于調(diào)控石墨烯內(nèi)稟缺陷的種類和含量可以較為簡便地實(shí)現(xiàn)對其本征力學(xué)性能的精確“剪裁”,使得石墨烯增強(qiáng)金屬基復(fù)合材料具有廣闊的發(fā)展空間。綜述了近年來石墨烯增強(qiáng)金屬基復(fù)合材料制備工藝與結(jié)構(gòu)-性能關(guān)系的研究進(jìn)展,并聚焦于石墨烯/金屬之間界面的結(jié)構(gòu)與性能。這不僅是因?yàn)樵趶?fù)合材料使役時,外加載荷是通過復(fù)合界面?zhèn)鬟f到石墨烯增強(qiáng)體的(即“承載效應(yīng)”),也因?yàn)殡S著石墨烯的加入,在復(fù)合材料變形過程中石墨烯和金屬基體內(nèi)的位錯發(fā)生復(fù)雜的相互作用,改變或影響了基體的變形機(jī)制,導(dǎo)致了額外的強(qiáng)韌化效果。最后,展望了石墨烯增強(qiáng)金屬基復(fù)合材料的發(fā)展趨勢,指出需要發(fā)展宏量制備工藝,并深入研究實(shí)際使役條件下復(fù)合材料的力學(xué)行為和性能響應(yīng)機(jī)制。
- Abstract:
-
Graphene and its derivatives are regarded as promising reinforcing agents in the metal matrix because of their excellent intrinsic mechanical properties. Considering the availability of graphene with various types, defect states and intrinsic properties, there exists a large space in tailoring the mechanical behavior of graphene reinforced metal matrix composites. This article reviews the recent developments on the processing and structure-property correlations of these composites. Particular emphasis is given to the structure and properties of the graphene/metal interfaces, as the external mechanical load is transferred between nanocarbon and the metal matrix across their interfaces. Moreover, in addition to the intuitive load-bearing effect of graphene, a copious interplay between graphene and dislocations in the metal matrix has been found, which alters the deformation mechanism and leads to additional strengthening. To meet the requirements of structural applications, scalable fabrication routes for the graphene/metal composites should be developed and the study on the mechanical behavior under real service conditions is to be carried out.
