采用旋转衬底，在770℃下用镍催化乙炔裂解制得了碳微线圈。考察了转速对碳线圈的成品率、形貌和手性的影响。由于衬底转速为180rpm，线圈成品率下降了35%-50%，得到了不规则的碳线圈，而不旋转的情况下得到了规则的线圈。不能得到具有选择性手性的碳线圈。
Carbon micro-coils were obtained by the Ni-catalyzed pyrolysis of acetylene at 770°C using a rotating substrate. The effects of the rotating speed on the coil yield, morphology and chirality of the grown carbon coils were examined. The coil yield decreased by 35–50% due to the substrate rotation of 180 rpm and irregular carbon coils were obtained, while regular coils were obtained without rotation. The carbon coils with a selective chirality could not be obtained.
