Corrosion resistance and lifetime of polyimide-b-polyurea novel copolymer coatings

Preparation of superhydrophobic polyimide films modified with organosilicasol as effective anticorrosion coatings

“…PIs are also utilized as stable organic coatings for anticorrosion purposes due to the advantages listed above. However, the limitation of PI as an organic coating lies in the water absorption [2], which is a drawback for its use in coating for anticorrosion. The adoption of fluorine-containing monomers can enhance the hydrophobicity of PI [3] but superhydrophobicity cannot be simply achieved with monomer substitution since the surfaces have to be rough.…”

Inhibition of mild steel corrosion in CO2 and H2S‐saturated acidic media by a new polyurea‐based material

“…Polyurea belongs to a class of organic polymers commonly used as protective coatings against metallic corrosion primarily due to their high thermal and chemical resistance, good abrasion resistance, molecular structure enhancement, waterproofing, and structural diversity . A number of studies on the corrosion inhibitive performance of polyurea coatings have been reported . The majority of these studies reported the utilization of polyurea derivatives as a coating for metallic structures primarily due to their lack of solubility in aqueous medium.…”

Polyimide–polyurea copolymer coating with outstanding corrosion inhibition properties

“…According to the previous report, a novel type of polyimide‐ b ‐polyurea block copolymers prepared by Iroh and coworkers showed promise as an effective anti‐corrosion polymeric coating because of its ultra‐low dielectric constant in a 3.5 wt % NaCl solution. The presences of hydrogen bond (H‐bond) donor and H‐bond acceptor atoms in PI and polyurea blocks can lead to well‐controlled intra‐ and inter‐hydrogen bonding induced self‐assembly.…”
