Polypeptide ionic liquid: Synthesis, characterization, and application in single‐walled carbon nanotube dispersion

Abstract

Polypeptide ionic liquids with a helical polypeptide main-chain and N-butyl imidazolium side chains have been synthesized via copper-mediated [2+3] alkyne–azide 1,3-dipolar cycloaddition. They showed superior single-walled carbon nanotube (SWCNT) dispersibility in water (up to 1045.8 mg L-1) depending on the polymer-to-SWCNT weight ratios and polypeptide main-chain lengths.
