Abstract: Low-dimensional carbon nanomaterials,including fullerene,carbon nanotube and grapheme,are the research hotspot in the field of nanomaterial and nanotechnology. In this paper,three kinds of typical low-dimensional carbon nanomaterials were selected as the research object. Patent information about the three kinds of low-dimensional carbon nanomaterials was collected by Derwent innovations index database from 2005 to 2015. Through analyzing the granted patent numbers,country distribution of patent applications,patentee's names,subject category and the international patent classification code,the authors found that in recent years,researchers has gradually paid pay more attention to grapheme,but less to carbon nanotubes and fullerene. By the analysis of the technical innovation status and the development trend of low-dimensional carbon nanomaterials,we also revealed the existing problems in the further development of low-dimensional carbon nanomaterials. The development levels of low-dimensional carbon nanomaterials in different research fields are unbalanced,and there is still lack of comprehensive development strategy. The industrialization of technological achievements and the research outcomes of original innovation is still problematic and the investment for research and development is insufficient. This article also gave the corresponding suggestions about the restrictions of developing low-dimensional carbon nanomaterials. The results will provide references for the technical innovation and strategic development of low-dimensional carbon nanomaterials.
