Ionic Liquid Mediated Conductive Polymers

摘要

Room temperature ionic liquids (RTILs) are salts with melting points close or below room temperature, 30°C. Most polymers in the industry have shown to display hydrophilic characteristics, which have had more scientists paying much attention for membrane electrolyte during the past few years. The first work to become published in the study for solid polymer electrolyte was carried out by Wright and co- workers [1,2] and was devoted to the ionic nature for their conducting behavior. Scientists have used ionic liquids, also known as plasticizers, as organic solvents and supporting electrolytes in many fields due to their exceptional properties like high conductivity, non-volatility, non-flammability, etc. [3-8]. Due to the significant development of plasticizers to the conductivity, thermal and electrochemical properties of polymers, the merging of plasticizers into different polymers has been reported [9-11]. In order to overcome the brittleness of polymer films, the addition of plasticizers is important to improve flow and flexibility, and to increase toughness, to impact resistance of film coasting, and to prevent them from cracking during packaging and transportation [12, 13]. The compatibility and permanence is normally based on the selection of plasticizer for a specified system, the amount needed for plasticization, and the desired physical properties of the films [14].
