Grain: China ‘s patent output of the world leader

In the five years of scientific and technological achievements graphene has the reputation of the king of new materials, the world’s competition in graphene intensified. September 8, the Chinese Academy of Sciences Literature and Information Center and the American Chemical Abstracts Society jointly issued the “graphene R & D situation monitoring and analysis report” (hereinafter referred to as “report”), the competition added a detailed “Notes.” Graphene is a magical two-dimensional material. It has only one carbon atom in thickness and is composed of carbon atoms. In 2004, the two British physicists used the micro-mechanical stripping method for the first time to successfully remove the graphene from the graphite, confirming that the graphene crystals can be truly independent. They also won the Nobel Prize in Physics in 2010. As the world’s thinnest material, graphene has excellent mechanical, thermal and electrical properties. The world has formed a research boom in graphene because graphene “is likely to lead to subversive new technologies and new industrial revolutions as future cutting-edge materials.” Graphene research and development is in 2010 after the rapid development period. “Report” statistical analysis of the global published more than 70,000 pieces of graphene papers, more than 20,000 pieces of graphene patents, found that more than 50% of the world’s papers and patents focused on the published and applied in 2014-2016. Liu Xiaowen, deputy director of the Literature and Information Center of the Chinese Academy of Sciences, said at the press conference that the publication and patent applications of graphene papers have continued to rise in the past three years, and their basic research and technology applications are still developing rapidly. Statistics show that the top five countries produced by graphene papers are China (excluding Hong Kong, Macao and Taiwan regions), the United States, South Korea, Japan and India, the total number of papers accounted for 64.3% of the total global; patent application of the top five The country for China, Korea, the United States, Japan and Germany, the total number of five countries accounted for more than 90% of the global total. “China, the United States, Korea, Japan and other countries competing for the application of graphene frontier technology, the United States, Japan published papers and patent applications earlier, Chinese papers and patent output has been leading the world.” From the five countries to apply for investment, Graphene patent flow to the United States, mostly in the majority. China’s patent applications are high, but China’s shareholding in China, Korea, Japan, Germany and Germany is only 2.3%, while the share of patents in Korea, the United States, Japan and Germany in the other four countries is 27.8 %, 24.8%, 32.3%, 45.3%. “Relatively speaking, the layout of Chinese patents in other countries is relatively weak.” “Report” that the global competitive landscape of graphene, China, the United States, Korea, Japan has formed a technological advantage. Graphene research papers and patents are mainly distributed in the fields of electrical phenomena, electrochemistry, radiation and thermal energy technology, optics, electronics, mass spectrometry and other related properties, surface chemistry and colloids, silicates and the like. In recent years, the development of graphene in the field of electrochemical, radiation and thermal technology, optical, electronic, mass spectrometry and other related areas, biochemical methods, plastics production and processing, electrochemical and other areas of the proportion of research increased year by year. Statistics show that papers published by Chinese organizations focus on applications such as sensors, electronics and optoelectronics, and batteries. US papers focus on applications such as optoelectronic properties, electronic structures, thin film transistors, and semiconductor devices. Korean papers focus on Capacitors and other aspects of the study; Japanese institutions published papers focus on electrical performance and other aspects of the study. “Report” pointed out that a short period of 10 years, the study of graphene from the material mechanics and electronic properties of basic research extended to the battery, capacitors, semiconductors, sensors, polymer nanocomposites and other applications, future applications The field will continue to expand. As the president of the Chinese Academy of Sciences Bai Chunli said, graphene is a subversive material, “scientific research personnel and industry are its technology research and development breakthrough and subversive applications high hopes.”
