Novel interfacial polymerization for radially oriented polyaniline nanofibers

A novel interfacial polymerization method derived from the self-assembly method is presented in this paper for the generation of radially oriented polyaniline nanofibers. Salicylic acid (SA) was used as dopant and the diameters of polyaniline-SA nanofibers range from 300 to 500 nm. Compared with the previous interfacial polymerization methods, no organic solution was added in our method. The organic phase formed in our experiment is made up of a monomer (aniline) and a dopant (salicylic acid: SA) and their amounts were increased. Scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectra are used to characterize the products.
