Poly Ionic Liquid

Imidazolium-based poly(ionic liquid)s were synthesized and used as sensing film for the adsorption of volatile organic compounds. Based on a quartz crystal microbalance system, the sensing properties of the imidazolium-based poly(ionic liquid)s on volatile organic compounds was assessed according to the position of imidazolium cation in the polymer chain (the main-chain or side-chain type) and the varied counterions. The results indicated that the imidazolium-based poly(ionic liquid)s films have much higher adsorption capability on volatile organic acids than other volatile organic compounds, which is due to the strong affinity between imidazolium group and the carboxyl group. The position of imidazolium cation in the polymer chain and counterions of the imidazolium-based poly(ionic liquid)s was found to be able to influence the selectivity and sensitivity of volatile organic acids. The main-chain imidazolium-based poly(ionic liquid)s were shown strengthen the adsorption of propionic acid vapor, while the counter ion of dicyanamide showed the highest selectivity on volatile organic acids. Based on the quartz crystal microbalance sensing system, the imidazoliumbased poly(ionic liquid)s film was shown capable of detecting volatile organic acids with a theoretical detection limit of about 3.1 ppb and a quick recovery time less than 40 seconds. The sensing performance is also stable for repeated usage and after long-time storage.
