提高注射成型聚合物的强度重量比可以使广泛的应用受益，例如汽车，飞机和消费电子设备。本文表明，将微量（0.1 wt %）的气相合成石墨烯加入到丙烯腈-丁二烯-苯乙烯（ABS）中，可以显著提高注射成型样品的强度20%以上。研究结果改变了我们目前对石墨烯填充聚合物基纳米复合材料结构-性能关系的理解，因为具有非功能化表面和纳米尺度横向尺寸的高度卷曲的石墨烯片被证明比具有功能化表面和微米尺度横向尺寸的扁平石墨烯片更有效地增强ABS。
Increasing the strength-to-weight ratio of injection moldable polymers can benefit a broad range of applications, such as automobiles, aircraft, and consumer electronic devices. This paper demonstrates that incorporating miniscule quantities (0.1 wt %) of gas-phase-synthesized graphene into acrylonitrile–butadiene–styrene (ABS) can significantly increase the strength of injection-molded specimens by over 20%. The results transform our current understanding of the structure–property relationships of graphene-filled polymer-matrix nanocomposites because highly crumpled graphene sheets with nonfunctionalized surfaces and nanometer-scale lateral dimensions are shown to be more effective at strengthening ABS than flat graphene flakes with functionalized surfaces and micrometer-scale lateral dimensions.
