国内外可降解膜研究热点及趋势对比分析

Comparative analysis of research hotspots and trends of domestic and foreign biodegradable films

结合文献计量学和内容分析法,通过对2000—2020年间中国知网和Web of Science核心数据库中1 932篇与“可降解膜”相关中英文文献客观、系统地分析,对比了国内外可降解膜的研究进展。分析了国内外可降解膜研究历程、主要研究力量,包括国家、机构和作者。对比分析了国内外可降解膜研究前沿及热点的演变,主要包括可降解膜的类型、可降解膜性能优化方法及其在多个领域的应用效果评估。结果表明,低成本、高性能可降解膜研发及其全生命周期环境风险评估等是未来可降解膜的研究重点。

In this study, a comparative analysis of domestic and foreign studies on biodegradable films(BM) was performed by a combination of bibliometric visualization technology and content analysis to present an objective and systematical overview of global BM research. A total of 1932 English and Chinese literatures related to BM from the China National Knowledge Infrastructure(CNKI) and the Web of Science Core collection were analyzed to elucidate its development history and most influential contributors including countries, institutions, and authors. Furthermore, the domestic and foreign research frontiers and hotspots of BM were identified, including the types of BM, the optimization of the performance of BM, and the application effectiveness of BM in various fields. The development of novel low-cost and highperformance BM products and their life cycle environmental risk assessment are of great significance in the global future study.
