In this experiment you will analyse some innovative materials that are highly water repellent, stainless and require less cleaning thanks to their surface nano-engineering. Those materials have been developed using nature as an inspiration, since some plant leaves have exceptional properties due to their surface composition.
The property you will analyse is the superhydrophobic effect found in some leaves, such as the lotus leaf. The effect is due to interplay of surface chemistry and surface topography at the micro- and nano-level.

WATER PROOFING FOR BUILDING
The treatment given to prevent leakage of water from external source is generally termed as WATER PROOFING.
Usually extensive waterproofing measures are added to a building at the time of construction ,to provide moisture control form starting.
Waterproofing may also be done after a building is built ,to address problems as they emerge or as part of building retrofit.
Nanotechnology is seen as one of the key technologies of the future. Nanotechnology refers to a wide range of scientific and technological phenomena which focuses on nanoscale (0.1 to 100 nm). It is the science of developing materials through individual control of atoms and molecules to create products that are thousands of times smaller than current technology allows for. The basis of this technology is to modify the inherent material properties such as color, abrasion resistance, conductivity, etc. the reduction of its size without modifying its chemical composition. nano-particles artificially produced have new properties which are important for the development of new products and applications.
The composition of an organic coating (paint) may be may be a formulation simple or complex, with a variety of materials, each having a specific function. The formulations generally have three components designed to be permanent and serve specific functions in the dry film. These components are the pigment, carrier and additives. Pigments provide color and other functions. The vehicles commonly called ligands act as an adhesive to adhere the pigment particles to the substrate or to each other. Finally, the additives are chemicals which modify the coating properties in fluid or solid state.

A Solution On Accumulated Dust On Solar PV_Nadira Salsabila.pptxnadirasalsabila10
The document proposes using a silicon nano coating to reduce dust accumulation on solar PV panels. It first discusses how dust can reduce the efficiency of PV panels and introduces the lotus effect where microstructures cause water to bead up and roll off surfaces. It then suggests that a silicon nano coating could mimic these microstructures, creating a rough hydrophobic surface that the lotus effect repels dust from. The coating would also provide benefits like reduced cleaning needs. Testing how long dust takes to accumulate on coated panels in Qatar and developing an automated water trickling system are proposed to further optimize the dust-resistant performance. In conclusion, the lotus effect from silicon nano coatings could effectively repel dust and require less frequent cleaning of solar panels.
