This research was conducted to obtain cis-oleyl imidazolinium iodide ionic liquid as an antistatic agent in ceramic and wood floor coatings. Synthesis of cis-oleyl imidazolinium iodide ionic liquid was carried out by reacting diethylenetriamine and cis-oleic acid in a ratio of 1:2 which was reacted utilizing microwave irradiation followed by quaternary methylation using methyl iodide. Then, Fourier-transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (¹H NMR), and carbon-13 nuclear magnetic resonance (1³C NMR) instruments were used to characterize the synthesis results. The results showed that the synthesis of cis-oleyl imidazolinium iodide ionic liquid was successful. The electrostatic effectiveness of the cis-oleyl imidazolinium iodide mixed ionic liquid floor coating is statically dissipative because the surface resistance values are in the range of 106 – 109 Ω. Optimum point-to-point resistance in coating mixture is 108 Ω (2-9 wt%), ceramic floor coating 108 Ω (7-9 wt%), and wood floor coating 108 Ω (7-9 wt%). Meanwhile, the optimum ground resistance in the coating mixture is 108 Ω (2-9 wt%), ceramic coating 109 Ω (4-9 wt%), and wood floor coating 109 Ω (1-9 wt%). The coated floor has a yellow color due to iodide which makes it unsuitable for use on white surfaces. Dust adhesion test results show that the mixed-coated floor attracts much less dust than the non-ionic liquid coating.
