采用硫酸和硝酸的化学方法，通过对催化化学气相沉积法生长的结晶多壁碳纳米管（MWCNTs）进行径向和纵向解链，制备了石墨烯纳米叶/碳纳米管/矩形石墨烯纳米片（GNSs）杂化结构.在纳米管的径向方向上，然后在纵向方向上连续解压缩从未被报道过。我们简单的化学方法将打开路径，以制造矩形GNS在几百纳米由几百纳米尺度和广泛的应用MWCNTs的新型碳纳米结构。(C)2011爱思唯尔有限公司版权所有。
A hybrid structure of graphene nanoleaves attached on a carbon nanotube and rectangular graphene nanosheets (GNSs) were fabricated by means of radial followed by longitudinal unzipping of crystalline multiwalled carbon nanotubes (MWCNTs) grown by catalytic chemical vapor deposition, using a chemical method containing sulfuric acid and nitric acid. Consecutive unzipping in the radial direction and then in the longitudinal direction of a nanotube has never been reported. Our simple chemical approach will open the path to fabrication for rectangular GNSs in the hundred nanometers by few hundred nanometers scale and a broad application of MWCNTs to the novel carbon nanostructure.
