Experimental, DFT and molecular dynamics simulation on the inhibition performance of the DGDCBA epoxy polymer against the corrosion of the E24 carbon steel in 1.0 M HCl solution

DGEBA‐polyaminoamide as effective anti‐corrosive material for 15CDV6 steel in NaCl medium: Computational and experimental studies

“…The bond length ranged from 1 å up to 3.5 å, which is correlated with chemisorption. The physical interactions are associated with bond length longer than 3.5 å . The RDFs for oxygen and nitrogen atoms in DEGBA‐polyaminoamide relative to Fe (110) surface are displayed in the Supporting Information Figure SI 1.…”

Adsorption and anticorrosive behavior of aromatic epoxy monomers on carbon steel corrosion in acidic solution: computational studies and sustained experimental studies

“…69 Positive values of DH a suggested that interaction of AEM1 and SEM2 with metallic surface is an endothermic process whereas large negative values of DS a suggested the creation of active complex and dissociation of the complex is the rate determining step. [70][71][72]…”

“…Literature study reveals that few of the aromatic epoxy monomers based organic inhibitors have been evaluated for their anti-corrosive behavior for metals and alloys in different electrolytic media. [14][15][16]71,72 Inhibition effectiveness of some common representatives of the similar inhibitors is presented in Table 3. It can be seen that these types of compounds are acted as good corrosion inhibitors and their molecules structures contain N, O, S and/or P heteroatoms along with the aromatic ring(s).…”

“…13,14 Recently, use of corrosion inhibitors based on some aromatic epoxy monomers (AEMs) has gained particular importance because of their relatively high protectiveness, the facile route of synthesis and high purity. 15,16 We herein, synthesized two aromatic epoxy monomers (AEMs) as trifunctional molecules designated as AEM1 and AEM2 and tested their anticorrosive properties on the corrosion of carbon steel in 1 M HCl media. Novelty, of the study is lying behind the facts that these AEMs have never be tested as corrosion inhibitors for steel alloys and they offer reasonably high inhibition efficiency at relatively low concentration.…”

Investigation of structure and rheological behavior of a new epoxy polymer pentaglycidyl ether pentabisphenol A of phosphorus and of its composite with natural phosphate

“…The polymers exhibit a rather particular rheological behavior when compared to other materials because of exhibiting viscosimetric behavior in the solid state and in the molten state [1,2]. The rheological evaluation of the epoxy resin and its composite under the conditions of the processing by injection is useful for the control of the quality of the material and at the same time for further improving the product.…”
