The Optimal Sulfonation Conditions of Self-doped Polyaniline Obtained by Using Experimental Strategies
摘要
Abstract
The optimal sulfonation condition of self-doped sulfonated polyaniline ( prepared from leucoemeraldine base; denoted as LEB-SPANI) with a high electronic conductivity was obtained by experimental strategies, including the fractional factorial design (FFD) and central composite design (CCD). From the FFD experiment, the selfdoped LEB-SPANI prepared at a low temperature (4℃), a short reaction time ( 1 h), and a small volume of fuming sulfuric acid ( 10 mL) showed a better conductivity (ca. 127 mS/cm). In the CCD study coupled with a confirmation test, the highest conductivity (ca. 141 mS/cm) of the LER-SPANI film was obtained under a sulfonation temperature of 4℃, a sulfonation time of 75 minutes, and a volume of 8 mL of 30% fuming sulfuric acid. The textural cha-racteristics of self-doped LEB-SPANI were characterized by Fourier transform infrared (FTIR) spectroscopy, four-point probe method, and X-ray photoelectron spectroscopy (XPS). The sulfonation rate and degree of LEB-SPANI were found to be dependent upon the acid used in the polymerization step of PANI.关键词
