摘要: 当前世界各国对环境保护和绿色发展的重视程度日益提升,离子液体因其优良的理化性能和可设计性,在能源、材料以及环境等众多领域展现出广阔的应用前景。基于全球专利信息,对离子液体领域三类热点应用,包括CO2捕集及利用、电化学储能和生物质转化利用的全球专利申请趋势、申请地域、重要专利权人、重点技术等情况进行国内外的比较研究。研究结果表明,离子液体技术分类布局广泛,尤其是催化分离的相关专利充足。中国在离子液体领域的专利申请量多,但专利权人以高校或科研机构为主,专利转化应用和保护力度不足。因此建议中国离子液体领域加强科研机构与新型能源/环保科技公司合作,向动力电池、碳捕集、生物基材料、废水处理、空气净化等方面开展转化和深度应用。

Abstract: Nowadays, countries all over the world pay more and more attention to environmental protection and green development. Ionic liquids have broad application prospects in many fields such as energy, materials and environment, due to its excellent physical and chemical properties and electrochemical properties. Based on global patent information, a comparative analysis was made on the global patent application trends, application regions, important patentees and key technologies of three popular applications in the field of ionic liquids, including CO2 capture and utilization, electrochemical energy storage, biomass conversion and utilization. It is found that ionic liquid technology has a wide classification layout and especially the related patents of catalytic separation are abundant. There are a large number of patent applications in the field of ionic liquids in China, but the patentees are mainly universities or scientific research institutions, and the patent transformation, application and protection are insufficient. Therefore, it is suggested that China strengthen the cooperation between research institutions and new energy/environmental protection technology companies in the field of ionic liquids, and carry out in-depth applications in power batteries, carbon capture, bio-based materials, wastewater treatment, air purification and other fields.
