“…Furthermore, a conjugated polymer with specific functional group(s) that has good adhesion to the metal can serve as both a corrosion inhibitor and a passivation layer promoter. Based on this concept, a soluble poly triphenylamine (PTPA-C6) is synthesized and applied to the surface of iron substrate as a corrosion resistant coating by Tsai et al [ 37 ]. Functionality such as triphenylamine contains a nitrogen atom that has been proved to be effective in corrosion protection of metals.…”

An electroactive polytriphenylamine (PTPA-C6) is blended with poly(styrene-co-hydroxystyrene) (PS-co-PHS) as coating layers to enhance protection efficiency of PTPA-C6 on iron substrate in 3.5% sodium chloride (NaCl) solution. Experimental results show that incorporation of hydroxyl group to the polystyrene not only increases the miscibility of PTPA-C6 with PS through the hydrogen bond formation, but also enhances the bonding strength between the polymer coating layer and iron substrate. These improvements lead to superior enhancement in anticorrosion performance of PTPA-C6, even after thermal treatment. Protection efficiency (PE) of PTPA-C6 increases from 81.52% of the PTPA-C6 itself to over 94.40% under different conditions (PEmax = 99.19%).

“…P3HT/PMMA blend gave the best protraction to the steel. To enhance the interface interaction between different polymers in the blend, Huang et al [64] reported the preparation of P3HT/poly(styrene-cohydroxystyrene) blend (P-10 in Figure 6) via the intermolecular hydrogen bonding between thiophene and phenol group. The hydrogen bonding not only improved the miscibility between two polymers, but also enhanced the adhesion force between iron and coating layer.…”

An anti-corrosion inhibitor is one of the most useful methods to prevent metal corrosion toward different media. In comparison with small molecular inhibitors, a polymeric inhibitor can integrate more adsorption groups and generate a synergetic effect, which has been widely used in industry and become a hot topic in academic research. Generally, both natural polymer-based inhibitors and synthetic polymeric inhibitors have been developed. Herein, we summarize the recent progress of polymeric inhibitors during the last decade, especially the structure design and application of synthetic polymeric inhibitor and related hybrid/composite.

An electroactive poly(triphenylamine) (PTPA‐C6) is applied to the surface of iron as a corrosion‐protection layer. The iron substrate coated with PTPA‐C6 is thermally treated at different temperatures (up to 80°C) to study the effect of thermal treatment of PTPA‐C6 on the corrosion behavior of iron. Experimental results indicate that the contact angle of the PTPA‐C6 film increases from 81.6° at room temperature to 100° after thermal treatment at 80°C for 1 hr. The surface becomes more hydrophobic after thermal treatment, which will lower the penetration of water to the iron surface. Adhesion tests (ASTM 3359) indicate that adhesion between the PTPA‐C6 and iron substrate is enhanced after thermal treatment. Additionally, a thin iron oxide layer formed between the PTPA‐C6 and iron substrate as a passivation layer. The synergistic effect of these factors makes PTPA‐C6 a very effective corrosion protection layer on iron substrate after appropriate thermal treatment. Corrosion protection efficiency increases from 90% of the pristine PTPA‐C6 to 99.9% of the 80°C treated PTPA‐C6.
