Biowaste utilisation to fabricate corrosion retarding nanofiller MA/LS (Mango kernel ash/Lauric acid treated SiO2) blended epoxy coating for low alloyed carbon steel in saline medium
In present work, Mango fruit biowaste (collected from local juice shop) was utilised to fabricate MA/LS (Mango kernel ash/Lauric acid treated SiO2) composite by simple sol-gel technique, to fabricate low cost and non-hazardous corrosion retarding nanofiller for epoxy coating. Fabricated composite was added as nanofiller in epoxy to get composite epoxy coating (EP/MA-LS) and then was examined for corrosion resistance by utilising EIS and salt spray analysis. EP/MA-LS has offered excellent Rp value of 2.27 × 108 Ω cm2 as observed from EIS FRA measurement and protection efficiency of 89.32 % (measured from potentiodynamic linear polarisation) even after 51 days of prolong exposure in 3.5 % NaCl. Wettability examination of EP/MA-LS has demonstrated high hydrophobicity with contact angle of 122.3°. Improved thermal stability and better compactness was also observed for EP/MA-LS on examining with TGA and SEM respectively.
