Summary: The 2D few-layered Ti3C2Tx MXene nanosheets were prepared through etching and delamination of aluminium layers from the Ti3AlC2 MAX phase. The electroactive polyamide (EPA)/Ti3C2Tx MXene nanocomposites (NCs) containing various amounts of MXene were synthesized via in-situ oxidative coupling polymerization. The NCs showed improved physical properties such as electrical conductivity, thermal stability, and adhesion strength due to the close interaction between EPA and MXene. The addition of Ti3C2Tx MXene did not affect the surface roughness and water contact angle of the EPA matrix. The NCs coated samples exhibited improved tribological properties, and the corrosion study demonstrated excellent corrosion protection ability of EPA/Ti3C2Tx MXene NCs containing 1.2 wt% MXene.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
