The growing emphasis on sustainable and environmentally friendly materials has underscored the use of ionic liquids (ILs) as green additives in polymer science. Alkylimidazolium chloride ionic liquids (ACLs) have emerged as viable possibilities for improving the performance of rubber composites while minimizing the environmental impact of conventional processing aids. This research conducts a thorough examination of the function of ACls in rubber technology, focusing on their physicochemical features, interaction mechanisms with rubber matrices and curing chemicals, and their impact on the vulcanization process.Multiple preparation techniques for ACls-based rubber composites are examined, encompassing traditional two roll mill mixing, in situ polymerization using pre-dispersed ILs, solution mixing, and latex compounding. These methodologies provide adaptability in processing and facilitate the optimization of composite characteristics based on the specific rubber, filler, and ionic liquid employed. The choice of preparation process profoundly impacts ACls dispersion, filler interaction, and compatibility with the rubber matrix, hence affecting the performance of the finished material.Particular attention is placed on the capacity of ACls to facilitate uniform filler distribution, expedite curing kinetics, and improve the mechanical, thermal, and dynamic characteristics of rubber products. The environmental advantages of ACls, including low volatility, high thermal stability, and potential recyclability, are examined within the framework of green chemistry and sustainable manufacturing. This study consolidates previous achievements to highlight the promise of alkylimidazolium chloride ionic liquids as multifunctional, environmentally acceptable additives for the next generation of high-performance rubber composites.
