PHÁT TRIỂN COMPOZIT TRÊN CƠ SỞ POLYMER DẪN KẾT HỢP VỚI NANO SILICA ỨNG DỤNG TRONG LỚP PHỦ BẢO VỆ CHỐNG ĂN MÒN CHO THÉP CACBON

Tóm tắt

Over the past few decades, nanotechnology has made great breakthroughs for a variety of applications
including applications in corrosion protection coatings for materials. In this study, we present a simple
technique to synthesize nanocomposite based on polypyrrole and nano-additive SiO2. A corrosion
inhibitor of sodium dodecyl sulfate (DoS) added to the composite to improve corrosion resistance
performance of the material. Spherical nanoparticles of SiO2 with sizes in the range 250-500 nm were
obtained by in stitu method. The presence of the dodecyl sulfate anion did not change the morphology
of the synthesized composite. The electrochemical properties of these materials show that the presence
of the SiO2-PPy-DoS composite improved the protect ability for cacbon steel.
