Synthesis and barrier properties of a film polymer nanocomposite based on polystyrene and cadmium sulfide nanoparticles

摘要

A film polymer nanocomposite with nanoparticles of a chalcogenide semiconductor, CdS, in a polystyrene matrix was prepared on the surface of 08kp steel. The barrier properties of the synthesized two-layer film nanomaterial in a 3 wt aqueous NaCl solution were evaluated by measuring the electrode potential of coated and uncoated specimens and were compared with those of polymer films without nanofiller and with Fe3O4 nanoparticles. Introduction of hydrophobic CdS nanoparticles into the polymer matrix leads to significant enhancement (by similar to 20, as compared to Fe3O4) of the barrier properties of the polymer nanocomposite.
