摘　　要：在十二烷基磺酸钠(SDS)胶束微环境中,用大豆过氧化物酶(soybean peroxidase,SBP)催化合成了水溶性聚苯胺.在pH(4-5),0.1%-1.0%SDS胶束微环境中,SBP能催化苯胺聚合,产物在720 nm处有一明显的吸收峰.由于苯醌和苯环的变形振动,其红外光谱在1594 cm-1和1497 cm-1处有明显的吸收峰.由于C-H面外振动,在824 cm-1处有一单吸收峰.测量结果表明产物为头尾相连结构.A new method for the synthesis of water-soluble polyaniline with the soybean peroxidase （SBP） enzyme in the sodium dodecylsulfonate （SDS） micellar solution is reported. The structure of polyaniline is characterized by a UV-VIS and FTIR spectrums. The UV-VIS absorption spectra of the products display a distinct absorption peak at 720 nm from pH 4.0 to 5.0 and 0.1%-1.0% SDS, and FTIR spectrums at 1594 cm^-1 and 1497cm^-1 due to quinone and benzine ring deformation and 824 cm^-1 C--H out of plane bending. These results indicate that the structure of the polymer is head-to-tail forms.
