Microscopic Studies of Polyaniline-poly-N-isopropylacrylamide/Alumina Composites Containing Dodecylbenzene Sulfonic Acid

摘要

The polyaniline (PANI) composites containing poly(N-isopropylacrylamide-co-acrylic acid/alumina) (PNA/ Al2O3)) were synthesized by chemical polymerization of aniline in an aqueous solution containing dispersed PNA/Al2O3 in the presence of dodecylbenzene sulfonic acid (DBSA). The topography of obtained composites was investigated with scanning electron microscopy (SEM) and atomic force microscopy (AFM). Thermal stability was reasserted by thermogravimetric (TGA) and differential scanning calorimetry (DSC). A correlation in the surface modification of the composite between Al2O3 and PANI-PNA has been discussed.
