Porosity was introduced into the silica film matrix using an acid-catalyzed sol-gel method with polyethylene glycol (PEG) as a porosity modifier. Silica sol modified with PEG4000 achieved optimal porosity (2-4 nm) and the highest transmittance (98.2%). A graphene layer was added to enhance hydrophobicity, achieving a contact angle of 105.3°, compensating for a slight transmittance reduction (1.15%). Atomic force microscopy and field emission scanning electron microscopy confirmed increased porosity and groove-like surface morphology. Contact angle measurements indicated strong van der Waals interactions between the porous silica film and graphene, leading to a hydrophobic and anti-corrosive AR coating.","brand":"LAP LAMBERT Academic Publishing","offers":[{"title":"Default Title","offer_id":53689702416726,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9786208440060_1_ff109c68-6818-4d89-b04e-409b2b0f9a7f.jpg?v=1781749079","url":"https:\/\/www.momoxbooks.com\/products\/jarnail-singh-graphene-nanoporous-silica-smart-antireflective-hydrophobic-coating-9786208440060","provider":"momoxbooks","version":"1.0","type":"link"}
