Polymerized ionic liquids (PolyILs) are promising candidates for a wide range of technol. applications due to their single ion conductivity and good mech. properties. Tuning the glass transition temperature (Tg) in these materials constitutes a major strategy to improve room temperature conductivity while controlling their mech. properties. In this work, we show exptl. and simulation results demonstrating that in these materials Tg does not follow a universal scaling behavior with the volume of the structural units Vm (including monomer and counterion). Instead, Tg is significantly influenced by the chain flexibility and polymer dielec. constant We propose a simplified empirical model that includes the electrostatic interactions and chain flexibility to describe Tg in PolyILs. Our model enables design of new functional PolyILs with the desired Tg. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4Formula: C5H11BrO).
1-Bromo-4-methoxybutane (cas: 4457-67-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin. Formula: C5H11BrO
