摘要:

通过智慧芽专利分析系统收集国内外纳米纤维素专利数据,运用定量的专利分析、专利地图聚类及多主路径方法,对纳米纤维素专利公开趋势、专利权人地域分布、主要专利权人、高被引专利、主要技术领域和技术演化路径进行分析。结果表明:纳米纤维素专利技术处于快速发展阶段,是国内外研究的热点;美国、中国、日本、印度、芬兰等国家处于领先地位;我国纳米纤维素专利申请以大学为主,专利数量众多,在世界范围内排名第一,但缺乏高质量、高影响力的专利,影响力有待提高;纳米纤维素的制备方法一直是重点,且应用领域非常广泛。

Abstract:

PatSnap was used to collect domestic and foreign patent data of nanocellulose, and then patent publication trends, countries of patent assignees, main assignees, highly cited patents, technical areas and technological evolution paths were analyzed by patent analysis, patent maps and multiple main paths method. The results show that the technology of nanocellulose is in a fast developing stage and it is the hotspot of the world; USA, China, Japan, India and Finland are the leading countries; China has a large number of patents, but the impact needs to be improved, the assignees are mainly universities; the preparation of nanocellulose is key point and the application is wide.

Key words: nanocellulose, cellulose nanocrystal, cellulose nanofibril, patent analysis
