Abstract
It has been determined that among all types of corrosions, water corrosion is responsible for a large fraction of the total expenditure incurred in several industries. Therefore it is imperative that we minimize the ill-effects of the aforementioned corrosion. Since Polyethylene Terephthalate (PET) absorbs very little water and shows good resistance towards it, it can be used to form a coating that will help protect several key equipment in industries such as boilers, pipes etc. Furthermore PET can easily be obtained from the discarded soft-drink bottles, alcoholic beverages etc. In addition to finding an effective means to combat water corrosion, the present study will also help to facilitate the overall reduction of PET waste using landfills and other waste disposal techniques. Basically the PET obtained from waste bottles is converted to  Bis-2 Hydroxyethyl Terephthalate (BHET) by transesterification, followed by the synthesis of poly ethylene terephthalate-co-isophthalate .The poly ethylene terephthalate-co-isophthalate is then converted into nano form through sonication technique . Mild steel has been chosen as the substrate for this study, due to its low cost and high preference in the salt industry. Polyethylene terephthalate-co-isophthalate nanoparticles are coated onto the substrates surface and is then  tested for its efficiency against 5% salt water solution using a salt spray chamber.

​​Keywords: Polyethylene; Terephthalate-co-Isophthalate; Anticorrosive coating; Nanoparticles; Salt spray analysis.
