Polymers and antibacterial coatings. Natures’ vast repertoire of generating functional materials from simple starting materials is shown no better than in the oxidative drying of oils to form excellent natural coatings. Efficient utilization of such mechanism and materials for the modern lab techniques would be ideal for a sustainable and green approach for the future technologies. This research project focused on developing and understanding the new green method to synthesize metal nanoparticles (MNPs) embedded paints, in a single-step, from common household vegetable oils and paints. Herein, naturally occurring oxidative drying process in oils, involving free-radical mediated cross-linking, is used as the fundamental driving force for reducing metal salts to MNPs in oil medium. This is an ongoing collaborative research effort between CCNY and Rice University, developing eco-friendly, scalable, and inexpensive process for nanomaterials synthesis.
