Solvent free synthesis of poly (N,N-Dimethylamino ethylmethacrylate-co-Acrylamide) hydrogel by ultrasonic irradiation

Smart hydrogels are a new interesting family of materials on the basis of their polymeric three-demential network, swellable characterization and sensitivity to environmentalphysical and chemical stimuli [1]. Among the green synthesis methods, sonochemical synthesis has been proven as theuseful technique to prepare various materials [2]. On the other hand, for attaining nanomaterials ultrasound irradiation can be a useful technique [3].
