摘要：
The synthesis of crystalline nanofibers of poly (2,3-dimethyl aniline) using interfacial polymerization is reported with dichloromethane-water and hexane-water interfaces as illustrations. Apart from the differences in the morphology, molecular weight and conductivity, there exist remarkable variations in the optical and electrical properties of the interfacially synthesized polymer in comparison with the conventional single phase method. Furthermore, the morphologies and conductivities of the polymer vary with the choice of interfaces and are attributed to the rate of polymerization as well as the solvent polarity. The origin of the crystallinity is ascribed to the reaction kinetics as well as nature of the oxidant. The electrochemical sensing of hydrogen peroxide using poly (2, 3-dimethyl aniline)-coated glassy carbon electrodes is investigated in neutral phosphate buffer solutions.
