Abstract: The self-cleaning effect is related to the contact angle - the angle formed at the three-phase boundary (liquid/solid/vapor) between the surface of a liquid drop deposited on the surface of a solid. The principle behind this technology is derived from the behavior of water droplets on the surface of lotus leaves (?Lotus Leaf Effect?). In this dissertation, simple, cost-effective and scalable nanostructures fabrication techniques, viz. Electrospinning/Electrospraying, have been investigated to develop durable, environment friendly, transparent, high performance liquid repellent (Hydrophobic/Superhydrophobic, Amphiphobic/Superamphiphobic coatings) self-cleaning coatings. To achieve this objective, suitable metal oxide and polymer based electrospun/electrosprayed surfaces have been developed and the self-cleaning attributes along with the optical and mechanical properties of the fabricated surfaces were thoroughly studied. Furthermore, the mechanism leading to the surface morphology and surface modifications that are performed to enhance the self-cleaning performance parameters have been also studied and analyzed.
