Carbon materials derived from fullerene are reported recently with unique structures and properties. However, only micrometer size samples can be obtained that limits the studying and exploration for membrane applications. Here, the preparation of a centimeter-size nanoporous amorphous carbon monolayer is reported by rapid pyrolyzing a Langmuir-Blodgett film of fullerene. The sample is fully characterized and the results indicate that the amorphous carbon monolayer derived from fullerene is metastable and insulating. The ionic transmembrane transport study demonstrates that the membrane is porous and cation selective with a selectivity of 26%. This work provides new insights into the controlled synthesis of large-size metastable amorphous carbon monolayer.
最近报道了源自富勒烯的碳材料具有独特的结构和性能。然而，只能获得微米尺寸的样品，这限制了对膜应用的研究和探索。在此，通过快速热解富勒烯的朗缪尔-布洛杰特膜，报道了厘米尺寸纳米多孔非晶碳单层的制备。对样品进行了全面表征，结果表明源自富勒烯的非晶碳单层是亚稳态且绝缘的。离子跨膜传输研究表明该膜是多孔的且具有阳离子选择性，选择性为26%。这项工作为大尺寸亚稳态非晶碳单层的可控合成提供了新的见解。
