Bio-based acrylated epoxidized jatropha oil incorporated with graphene nanoplatelets in the assessment of corrosion resistance coating

Vegetable oil has been extensively investigated as a precursor to the eco-friendly coating as an alternative to petrochemical-based resources due to its lower carbon footprint properties. In view of this, jatropha oil (JO), a type of non-edible oil, has received significant attention in this field....
