碩士 === 國立東華大學 === 化學系 === 96 === A new method for chiral polyaniline synthesis was developed by using ionic liquid. In this experiment, 1-butyl -3-methyl imidazolium hexafluorophosphate (BMIM-PF6 ) , water immiscible ionic liquid ( IL) as interfacial media was used to produce chiral polyaniline. The optimal conditions for chiral polyaniline synthesis as follows: 0.54M polyacrylic acid(template) and 0.14M ammonium persulfate(oxidant) were dissolved in 2M CSA solution, 0.54M aniline was dissolved in ionic liquid. The proportion of aniline and ammonium persulfate was 4:1；the ratio of aniline and polyacrylic acid was 1:1. The best chirality of polyaniline was obtained at low temperature such as 4℃, and polymerized for 48hr. The morphology of polyaniline was cylinderal in Scanning Electron Microscope image. The ionic liquid was superior to organic solvent for chiral polyaniline synthesis. Ionic liquid can be recovered and used repeatly for at least 10 times.
