Coatings and the environment: A review of problems, progress and prospects

Abstract

Coatings are surface protection applications providing decorative, functional, or both applications on their applied substrates. Its application on substrates can be ingases, liquids, or solids. The environmental issues stemming from coating application, especially those from petroleum base feedstock, cannot be over-emphasised.This paper is poised to examine the merits of biodegradable synthesised polymeric coatings from a renewable source (plant seed oils).Using seed oil as a feedstock for organic coatings involves functionalising the seed oil to create a reactive site for polymerisation.The use of nanoparticles also helps to fine-tune coatings properties, and sometimes they provide thermal stability, adhesion, chemical resistance, electrical conductivity, anticorrosive, antimicrobial, hydrophobicityproperties, etc.
