摘要

Novolac-based poly(1,2,3-triazolium)s with 1,2,3-triazolium side groups spaced by oligo(ethylene glycol), a new kind of poly(ionic liquid) membrane, was prepared via the well-known Click chemistry (1,3-dipolar cycloaddition reaction). The thermal properties, ionic conductivity and gas permeation performance of these self-standing membranes were investigated. The obtained membranes exhibit glass transition temperatures ranging from ?1 °C to ?7.5 °C, and a temperature at 10% weight loss above 330 °C. These membranes have good ionic conductivity ( σ _(DC) up to 5.1 × 10 ~(?7) S cm ~(?1) at 30 °C under anhydrous conditions) as compared with the reported 1,2,3-triazolium-based crosslinked polymers. And they could be potentially used for CO _(2) separation as they exhibit enhanced CO _(2) permeability up to 434.5 barrer at 4 atm pressure.
