【摘要】：【目的/意义】通过对全球聚酰亚胺中空纤维专利情报进行分析,揭示相关领域的发展方向,为我国在该领域的技术发展提供信息参考。【方法/过程】本文利用Innography专利检索和分析平台,对全球聚酰亚胺(PI)中空纤维专利情报进行分析,内容包括专利申请趋势分析、技术应用国分布、技术发明国分布、专利权人分析、专利价值评价等。利用Innography新的分析功能对聚酰亚胺(PI)中空纤维专利技术申请量TOP5机构的研究热点、专利布局进行了分析,对比国外竞争对手研发热点,为国内研发方向提供参考。对挖掘出的核心专利内容进行了分析探究。【结果/结论】分析结果表明,美国、日本、德国、韩国、法国等在聚酰亚胺中空纤维领域的技术实力较强,拥有各自独特的核心专利内容。中国虽然是该项技术的主要应用国和技术发明国,但尚未拥有核心专利。目前聚酰亚胺中空纤维的研究热点主要为用于气体分离的中空纤维膜的制备和应用。
[Abstract]:[objective / significance] through the analysis of patent information on polyimide hollow fiber worldwide, to reveal the development direction of related fields, This paper analyzes the patent information of global polyimide (PI) hollow fiber by using Innography patent retrieval and analysis platform, including patent application trend analysis. Technology application country distribution, technology invention country distribution, patent owner analysis, patent value evaluation, etc. The research focus and patent layout of polyimide (PI) hollow fiber patent application volume (TOP5) are analyzed by using the new analysis function of Innography. The research hotspots of foreign competitors are compared and the reference for domestic research and development is provided. The core patent contents are analyzed and explored. [results / conclusions] the results show that the United States, Japan, Germany, South Korea, France and other countries have strong technical strength in the field of polyimide hollow fibers. Has their own unique core patent content. Although China is the main application and invention country of the technology, it does not have the core patent. At present, the research focus of polyimide hollow fiber is the preparation and application of hollow fiber membrane for gas separation.
