Synthesis of polyaniline doped with decylphosphonic acid by interfacial polymerisation
The polyaniline nanofibers were successfully synthesised by interfacial polymerisation at room temperature using a solution of aniline in toluene as the organic phase, ammonium peroxydisulfate oxidant (APS) and decylphosphonic acid (DcPA) as the aqueous phase. This PANI synthesis was realised at the Petrochemical Laboratory of Danang University of Technology - University of Danang. The FT-IR and UV-vis absorption spectra were used to characterise the molecular structures of the polyaniline obtained from this method. The polyaniline doped with decylphosphonic acid (PANI-inter-DcPA) has a uniform nanofiber structure with the average diameter of about 50nm as observed by scanning electron microscopy (SEM).
