Synthesis of polypyrrole-magnetite/silane coatings on steel and assessment of anticorrosive properties
This work presents a detailed study of the synthesis of polypyrrole-magnetite/silane coatings
(PPy-Fe 3 O 4/GPTMS-TEOS-γ-APS) and their anticorrosion properties. The use of a bilayer
system is proposed consisting of a PPy-Fe 3 O 4 internal conductive coating (active coating),
obtained electrochemically, and an outer coating or insulating barrier consisting of silanes
(passive coating). This latter is composed by Tetraethoxysilane (TEOS),
glycidoxypropyltrimethoxysilane (GPTMS) and γ-aminopropyl-silane (γ-APS). The GPTMS …
