Insights into Ionic Liquids for Flame Retardant: A Study Based on Bibliometric Mapping

Abstract

Fire is a typical disaster in the processing industry. Ionic liquids, as a type of green flame retardant, play an important role in process safety. In order to grasp the current research status, hotspots, and frontiers in the field of ionic liquids in flame retardancy, the bibliometric mapping method is applied to study the relevant literature in Web of Science datasets from 2000–2022 in this paper. The results show that the research on ionic liquids in flame retardancy is multidisciplinary and involves some disciplines such as energy science, material science, and environmental protection. Journal of Power Sources, Polymer Degradation and Stability, ACS Applied Materials and Interfaces, and Chemical Engineering Journal are the core journals in the field. The results of keyword co-occurrence indicate that the hotspots of research can be divided into five components: the improvement and application of pure ionic liquids electrolytes, the research of gel polymer electrolytes, applying ionic liquids to enhance the polymer materials’ flame retardancy properties, utilizing ionic liquids and inorganic materials to synergize flame retardant polymers, and using ionic liquids flame retardant to improve material’s multiple properties. The burst terms and time zone diagram’s results point out the combination of computational quantum chemistry to study the flame retardancy mechanism of ionic liquids, the study of fluorinated electrolytes, ionic liquids for smoke suppression, phosphorus-containing ionic liquids for flame retardant, and machine learning-assisted design of ILs flame retardants are the research frontiers and future research trends.

Mapping the Knowledge Domain of Corrosion Inhibition Studies of Ionic Liquids

“…If two or more papers were cited simultaneously by one or more later articles, it is regarded as a cocitation relationship. These cocited literature forms the knowledge base of the research field, while the journals carrying the cocited documents were the carriers of the knowledge base . Thus, we can get the high cocitation literature, analyze which literature is more closely linked, and speculate the knowledge base in ionic liquid corrosion inhibition.…”

In this section, we conducted a literature cocitation mapping using Gephi software, as shown in Figure 6.…”

Conductive Gels for Energy Storage, Conversion, and Generation: Materials Design Strategies, Properties, and Applications

“…Non-flammable alternatives, such as deep eutectic solvents and ionic liquid-based electrolytes, have been explored to mitigate this hazard. However, polymer electrolytes, while non-flammable, often suffer from deformation and breakage during the charge-discharge process, leading to interface contact issues [154][155][156]. Addressing this challenge, self-healing electrolytes have emerged as a promising solution, capable of inhibiting such problems and improving electrochemical performance while reducing degradation.…”

Insights into Ionic Liquids for Oil Desulfurization: A Study Based on Bibliometric Mapping

“…They mostly exhibit green and friendly properties such as high stability, low volatility, and recyclability. , Therefore, the research on ionic liquids has been welcomed by more and more scholars.
