Synthesis of polyaniline nanofibers with high electrical conductivity from CTAB-SDBS mixed surfactants
Abstract: Molecular surface active agent is composed of two distinct particles, a particle is much more lipophilic, the other has a highly hydrophilic. Dissolved in water, the surface tension of the surfactant can reduce water, and increase the soluble organic compounds. This paper is composed of sixteen alkyl three methyl bromide (CTAB) and sodium twelve sodium dodecyl benzene sulfonate (DBSA), used in the preparation of polyaniline (PANI) one-dimensional structure and high conductivity of soft. However, by enzymatic reaction, the utility model has the advantages of high specificity, especially for the stereoisomers (optical specificity); mild condition, temperature and pressure, don't need equipment high-temperature high-pressure catalytic rate is high. Soft template has a dual role in the reaction mixture of surfactant and dispersant. By changing the proportion of surfactants, the pH of buffer solution, and some inorganic salt, add some conditions for the synthesis of polyaniline, the fastest, highest yield condition. In addition, with the infrared spectrum measurement can more easily find the best condition.
