Abstract
The application of conductive polyaniline (PANi) on the related electronic industry has become more and more interesting and popular. In this research, the chemical oxidization method was used to prepare emeraldine salt (ES) type PANi doped with dodecyl benzene sulfonic acid (DBSA). Moreover, in this study, we dissolved PANDB and ABS soluble in chloroform and prepared ABS/PANDB blend films with various blend ratios by solution blend method. Thermogravimetric analysis (TGA) was used for the thermal degradation analyses of ABS/PANDB blend films with various blend ratios. The surface electronic reslstane was also determined. Also, the dispersions of PANDB in the blend film were examined by optical microscope.
