Abstract

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 R_p 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.
