Zirconium tetrachloride (ZrCl4, 98%) and 2-Aminoterephthalic acid (ATA, 99%) were used as metal and organic precursors of MOF, respectively bought from Sigma-Aldrich. Utilized solvents including methanol, N, N-dimethylformamide (DMF, 99%), nitric acid (HNO3, 68%), sulfuric acid (H2SO4, 98%) and acetic acid (HAc, 98%) were provided by Merck company. Carbon nanotubes were purchased from PlasmaChem GmbH and used without further purification. Epoxy resin (Araldite GZ7 7071X75: solid content: 74–76%, epoxy value: 0.15–0.17, density: 1.08 g/cm3) was purchased from Saman Co. Furthermore, amido polyamide curing agent based on CRAYAMID 115 (Arkema Co.) was employed as curing agent. In this research work, mild steel (CK10) was used as substrate. The chemical composition (wt.%) of the steel was as follows: 0.1 wt.% C, 0.45 wt.% Mn, ma × 0.4 wt.% Si, and about 99 wt.% Fe. Steel panels were cut into the size of 30 × 20 × 1 mm and 80 × 50 × 1 mm. Then the surface was polished with SiC paper of graded grit sizes ranging from 120 to 1500 to achieve a mirror-shinning surface then ultrasonically cleaned in a mixture of acetone and ethanol for 10 min. Finally samples were washed with distilled water and then dried in air.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
