Polyaniline (PANI), which is a member of the family of electrically conducting polymers, has been widely discussed as a potential membrane for wastewater treatment. Although a steady growth in PANI literature was observed, analyzing PANI literature quantitatively is still a novelty. The main aim of this study is to unearth the current research status, global trends, and evolution of PANI membranes literature and their use in water treatment applications over time. For this purpose, a scientometric study was performed consisting of bibliometric and bibliographic analysis. A total of 613 entities were extracted from Web of Science published during the last 50 years and were analyzed to map trends based on leading peer-reviewed journals, publication records, leading research disciplines, countries, and organizations. The study shows that the number of annual publications increased exponentially from 2005 to 2020 and is expected to keep increasing in the current decade. The published the highest number of articles and was identified as the most-cited journal in the field. China, India, and the USA were observed as the top three research hubs. The top-ranked authors in the field were Wang, Jixiao, and Wang, Zhi. To find research trends, four different clusters of keywords were generated and analyzed. The top five most frequent keywords turn out to be polyaniline, water, performance, membranes, and nanoparticles. The analysis suggests that the application of nanotechnology for modifying PANI membranes (using nanoparticles, nanotubes, and graphene specifically) is the future of this field. This study elucidates the research streamline of the field that may serve as a quick reference for early career researchers and industries exploring this field.
聚苯胺（PANI）是导电聚合物家族的一员，作为一种潜在的废水处理膜已被广泛讨论。尽管聚苯胺文献数量稳步增长，但对其进行定量分析仍然是一项新事物。本研究的主要目的是揭示聚苯胺膜文献的当前研究现状、全球趋势及其在水处理应用中的演变情况。为此，进行了一项科学计量学研究，包括文献计量分析和书目分析。从过去50年发表在《科学引文索引》上的文献中总共提取了613个实体，并基于领先的同行评审期刊、出版记录、主要研究学科、国家和组织对其进行分析以绘制趋势图。研究表明，2005年至2020年年出版物数量呈指数增长，预计在当前十年仍将持续增加。该期刊发表的文章数量最多，被确定为该领域被引用次数最多的期刊。中国、印度和美国被视为前三大研究中心。该领域排名靠前的作者是王继晓和王志。为了找出研究趋势，生成并分析了四个不同的关键词聚类。出现频率最高的前五个关键词是聚苯胺、水、性能、膜和纳米颗粒。分析表明，应用纳米技术改性聚苯胺膜（特别是使用纳米颗粒、纳米管和石墨烯）是该领域的未来发展方向。本研究阐明了该领域的研究流程，可为该领域的早期职业研究人员和行业提供快速参考。
