Novel soluble carbazole-based poly(aryl ether)s: Preparation, properties, and application for dispersing multiwalled carbon nanotubes

Effectively dispersing of carbon nanotubes (CNTs) is the key to producing high performance CNTs/poly(aryl ether)s (PAEs) composite materials. Here, a series of novel soluble carbazole-based poly(aryl ether)s with different alkyl side-chains were synthesized corresponding polymers P1, P2, P3, and P4, and characterized clearly by 1H NMR and IR. All the polymers exhibited good mechanical properties and thermostabilities (Tg ∼ 128–212 °C, Td5% ∼ 450–499 °C) as PAEs. Due to containing lots of large π-conjugated carbazole derivative units and possess suitable solubility, these non-conjugated polymers can wrap and disperse MWNTs well (238–416 mg/L) in CHCl3, and the similar work has been reported rarely. This excellent property makes these polymers become a promising and ideal type solubilizer for CNTs/PAEs composite. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46250.
