摘要：

To study the effect of a surfactant on the properties of polyaniline (PANI)/metal oxide composites, PANI/lead titanate (PbTiO3) composites were synthesized with different weight percentages (10, 20, 30, 40, and 50 wt %) of PbTiO3 in both the absence and presence of dodecylbenzenesulfonic acid (DBSA) by the polymerization of aniline with ammonium persulfate as an initiator. The structural characteristics and stability, surface characteristics, and electric properties of PANI/PbTiO3 and PANI-DBSA/PbTiO3 were studied and compared. The interfacial interactions and thermal stability of these composites were characterized with X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and thermogravimetry techniques. The results indicate significant changes in the physicochemical properties of the composites with the incorporation of DBSA. (c) 2008 Wiley Periodicals, Inc. J Appl Polym Sci 108:1070-1078, 2008.
