Ultrasonic Assisted Dynamic Inverse Emulsion:A Novel Polymerization Technique to Prepare Conductive Polyaniline/Palygorskite Composite

The present work describes an ultrasonic assisted in-situ dynamic inverse emulsion polymerization process of aniline (ANI) in the presence of organic palygorskite (OPGS) in toluene.Core-shell structure of electrically conducting polymerized ANI (PANI) combined with OPGS was prepared by utilizing the method.Dodecylbenzenesulfonic acid (DBSA) was used as the dopant and emulsifier.The OPGS was obtained via the chemical reaction of pretreated palygorskite with hexadecyltrimethyl ammonium bromide (HTAB).The prepared PANI/OPGS composite was characterized by FT-IR, UV-Vis, XRD, TGA and SEM.In addition, the conductivity was evaluated at different ANI/OPGS weight ratio.When the ANI/OPGS weight ratio increased to 2∶7, the conductivity of the composite still remained at 10 S/m at room temperature.The results demonstrated that ultrasonic assisted dynamic inverse emulsion would be an excellent polymerization technique to increase the conductivity and the polymerization rate.
