基于 Web of Science核心数据库,借助文献分析软件CiteSpace对 1953-2023 年的聚对苯二甲酸乙二醇酯(PET)结晶研究成果进行了可视化分析,分析了作者、国家、机构、关键词等合作网络,揭示了 PET 结晶研究的知识结构和发展演变.结果表明:PET结晶研究当前已进入相对稳定阶段,但合作网络整体比较分散,美国、中国是研究的中坚力量,中国科学院是影响力最大的研究机构;早期的研究偏向 PET 基础性能分析,后期的研究偏向 PET 的功能化制备;PET 的相结构、解聚、表征方法等是PET结晶研究的主要内容.
Analysis of Research Progress in PET Crystallization Based on Knowledge Graph
The research results of polyethylene terephthalate(PET)crystallization from 1953 to 2023 was visually analyzed based on the core database of Web of Science and with the help of literature analysis software CiteSpace,the cooperation network of authors,countries,institutions and keywords was analyzed,the knowledge structure and the evolution of PET crystallization research were revealed.The results show that PET crystallization research has entered a relatively stable stage at present,but the overall cooperation network is scattered.The United States and China are the backbones of the research,and the Chinese Academy of Sciences is the most influential research institution.Early research focuses on analyzing the basic properties of PET,while the later research focuses on functional preparation of PET.The phase structure,depolymerization and characterization methods of PET are the main contents of PET crystallization research.
