Preparation of 6-Diallylamino-1,3,5-Triazine-2,4-Dithiol Functional Nanofilm by Electrochemical Polymerization Technique on Aluminum Surface

The functional polymeric nanofilm of 6-diallylamino-1,3,5-triazine-2,4-dithiol monosodium (DAN) was successfully prepared by cyclic voltammetry and galvanostatic technique in NaNO2 supporting electrolyte on pure aluminum surface. Based on results of cyclic voltammetry and X-ray photoelectron spectroscopy (XPS), the mechanism of electrochemical polymerization was speculated, which indicated that the radical polymerization took place during the electrochemical polymerization process. The poly(6-diallylamino-1,3,5-triazine-2,4-dithiol) (PDA) functional nanofilm was also investigated by means of FT-IR spectra. The result also showed that the structure of polymeric nanofilm was consisted of Al2O3 and PDA. And the optimal electrochemical polymerization time of DAN at current density of 0.2 mA/cm2 at 298 K in NaNO2 solution is 6 min. It is expected that electrochemical polymerization technique will bring the direct joining between aluminum and rubber in the process of curing with the formed polymeric nanofilm
