[ 1 ] - Electrosynthesis, Characterization and Corrosion Inhibition Study of DBSA-doped Polyaniline Coating on 310 Stainless Steel

The synthesis of polyaniline doped with dodecylbenzene sulphonic acid (Pani-DBSA) coatings on 310 stainless steel (310 SS) surfaces has been investigated by using the galvanostatic method. The synthesized coatings were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), UV-Visible absorption spectrometry and Scanning Electron Microscopy (SEM...

[ 2 ] - Enhanced Anti-corrosive Properties of Electrosynthesized Polyaniline/zeolite Nanocomposite Coatings on Steel

The preparation of polyaniline/zeolite nanocomposite coating on 304 stainless steel (304 SS) surface has studied via the galvanostatic method. The electro-generated coating was characterized by Fourier transform infrared spectroscopy (FT-IR), UV-visible absorption spectroscopy, X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The anticorrosion property of polyaniline/zeo...

[ 3 ] - Two novel methods for synthesizing poly (propylene fumarate): Technical aspects and role of vacuum and N2 purging effects

Poly (propylene fumarate) (PPF), a linear unsaturated polyester consisting of alternating propylene glycol and fumaric acid units, can be cured in vivo to fill the skeletal defects with minimal surgical intervention. Many different methods have been reported for synthesizing PPF, but none of them gives a clear method. The present paper introduces two new methods in PPF synthesis: Modified reflu...

[ 4 ] - بررسی اثر محافظت در برابر خوردگی پوشش های اپوکسی اصلاح شده توسط نانوکامپوزیت های ZnO-Cr2O3 بر روی فولاد نرم

در این مطالعه، نانوکامپوزیتهای ZnO-Cr2O3 / اپوکسی برای حفاظت فولاد نرم در برابر خوردگی در محلول 3.5 درصد NaCl استفاده شد. عملکرد خوردگی پوشش های نانوکامپوزیتی با استفاده از طیف سنجی امپدانس الکتروشیمیایی (EIS) و اندازه گیری قطبی شدن پتانسیودینامیک مورد بررسی قرار گرفت. اندازه گیری های الکتروشیمیایی نشان می دهد که پوشش نانوکامپوزیتی ZnO-Cr2O3 دارای خواص حفاظتی خوب با درصد حفاظت حدود 99٪ در غلظت ...

[ 5 ] - Investigation of corrosion protection properties of TiO2-CdO nanocomposite coating prepared by sol-gel method on copper

the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...
