“…In recent years, a conceptually different approach has been developed by introducing polymer chains into the clay layers via click chemistry reactions as they bring a number of advantages, including high efficiency under mild conditions, and simple preparation set-up and purification steps [14][15][16][17][18][19][20][21][22]. In this way, clickable groups such as azide-alkyne [14-20], thiol-ene [23,24], thiol-epoxy [25,26], and maleimide-diene [27] partners can be integrated in either the clay surface or polymer chain-ends. The following click reaction such as copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC), gives highly exfoliated polymer/clay nanocomposites, as it can be carried out with high efficiency under ambient conditions [28,29].…”
