Carbon nanotube research developments in terms of published papers and patents, synthesis and production

AbstractProgress of carbon nanotube (CNT) research and development in terms of published papers and patents is reported. Developments concerning CNT structures, synthesis, and major parameters, in terms of the published documents are surveyed. Publication growth of CNTs and related fields are analyzed for the period of 2000–2010. From the explored search term, “carbon nanotubes”, the total number of papers containing the CNT concept is 52,224, and for patents is 5,746, with a patent/paper ratio of 0.11. For CNT research in the given period, an annual increase of 8.09% for paper and 8.68% for patents are resulted. Published papers for CNT, CVD and CCVD synthesis parameters for the period of 2000–2010 are compared. In other research, publications for CNT laser synthesis, for the period of 2000–2010, are reviewed. Publications for major laser parameters in CNT synthesis for the period of 2000–2010 are described. The role of language of the published references for CNT research for the period of 2000–2010 is also investigated. Published papers/patents in English, Japanese, Chinese, Russian, German, French, Polish, and Spanish languages are compared. As expected, the number of paper/patent publications in English dominates other languages
