Published in 2017 at "Journal of colloid and interface science"

DOI: 10.1016/j.jcis.2017.03.033

Abstract: Two N3-substituted imidazoles 1,2-dimethylimidazole and 1-butyl-2-methylimidazole were chosen to functionalize poly(aryl ether ketone), respectively. The generated imidazolium cations could electrostatically react with sulfonate ions of the sulfonated poly(ether ether ketone) forming the ionic crosslinking structure… read more here.
