Ionic Liquid‐Enhanced Epoxy/ SWCNT Composites in Anti‐Static Applications: Synergistic Effects on Mechanical, Morphological, Rheological and Electrical Properties

Carbon nanotubes (CNTs) offer exceptional electrical conductivity as conductive fillers; however, their tendency to aggregate limits practical applications. Ionic liquids (ILs) present significant potential to enhance CNT dispersion and electrical properties in coating systems. This study presents a systematic comparison of four ionic liquid types in self‐leveling antistatic epoxy floor coating applications. Conductive epoxy composites were prepared using single‐walled carbon nanotubes (SWCNTs) combined with ionic liquids, and their mechanical, morphological, rheological, and electrical properties were comprehensively investigated. A key finding is the achievement of antistatic properties at an exceptionally low SWCNT loading of 0.075 wt%, significantly lower than conventional carbon‐based systems. This optimal loading was determined through evaluation of antistatic properties, surface appearance, and viscosity‐flow characteristics. The ionic liquids demonstrated dual functionality: simultaneously enhancing electrical conductivity while maintaining favorable rheological properties for self‐leveling applications. The system incorporating 1‐ethyl‐3‐methylimidazolium dicyanamide at 0.075 wt% SWCNT exhibited superior performance. Mechanical testing revealed maintained compressive strength, SEM analysis confirmed CNT network formation, and accelerated weathering experiments verified long‐term stability of antistatic properties. Industrial‐scale production was validated through 150 kg batch manufacturing, confirming commercial viability. Overall results indicated that epoxy/SWCNT coatings combined with ILs represent a promising candidate as conductive coatings with improved leveling characteristics.
