Temiz suya erişim, doğal tatlı su kaynaklarının tükenmesi, küresel ısınma ve artan dünya nüfusu gibi etkenler nedeniyle, günümüzde karşılaşılan en önemli küresel sorunlardan biridir. Temiz su üretimi için genellikle ters ozmoz ve tuzdan arındırma yöntemleri kullanılmaktadır; ancak bu yöntemler yüksek yatırım ve enerji maliyetlerine sahiptir ve bu durum yaygın kullanımını sınırlamaktadır. Son yıllarda, atmosferik su toplama yöntemi olarak sis kullanımı, enerji verimli, düşük maliyetli ve çevre dostu bir alternatif yöntem olarak öne çıkmaktadır. Ancak, geleneksel sis toplama ağlarının verimliliği düşüktür ve bu durum, daha yüksek verimle sis toplayabilen malzemelerin geliştirilmesine olan ilgiyi artırmıştır. Bu çalışmada, çeşitli topografik yapılara sahip yüzeyler 3D baskı ile üretilmiş ve çevre dostu bir yöntem olan plazma destekli kimyasal buhar biriktirme (PECVD) tekniği kullanılarak, tek adımda hidrofilik poliakrilik asit (PAA) ve hidrofobik poliheksaflorobütil akrilat (PHFBA) ince filmlerle kaplanmıştır. Ayrıca, hem hidrofilik hem de hidrofobik özellikler gösteren yüzeyler tasarlanıp üretilmiştir. Kaplanmış yüzeylerin kimyasal yapısı, topografik özellikleri ve ıslanabilirlik karakteristikleri kapsamlı bir şekilde karakterize edilmiştir. Farklı yüzey yapıları ve ıslanabilirlik özelliklerine sahip toplam 22 örnek üretilmiştir. Sis toplama deneyleri, kontrol yüzeyle karşılaştırıldığında, geliştirilen yüzey tasarımlarının sis toplama veriminde %270'e varan artış sağladığını ortaya koymuştur. Elde edilen sonuçlar, yüzey topografyası ve ıslanabilirliğin sis toplama performansını etkileyen temel faktörler olduğunu göstermektedir.

Investigation of Fog Harvesting Performance of Functional Thin Film-Coated 3D Surfaces

Access to clean water is one of the major global challenges due to the depletion of natural freshwater reserves, exacerbated by global warming and increasing world population. Reverse osmosis and desalination methods are commonly used for clean water production; however, these methods have high investment and energy costs, limiting their widespread application. In recent years, atmospheric water collection, using fog, has emerged as an energy-efficient, low-cost, and environmentally friendly alternative method. However, traditional fog harvesting nets have low efficiency, prompting increasing interest in developing materials that can collect fog at higher yields. In this study, 3D printing was used to create surfaces with various topographies, which were then coated with hydrophilic polyacrylic acid (PAA) and hydrophobic polyhexafluorobutyl acrylate (PHFBA) thin films in a single step, utilizing the environmentally friendly plasma enhanced chemical vapor deposition (PECVD) technique. Additionally, surfaces exhibiting both hydrophilic and hydrophobic properties were designed and fabricated. The chemical structure, topographical features, and wettability characteristics of the coated surfaces were thoroughly characterized. A total of 22 samples with different surface structures and wettability properties were produced. Fog harvesting experiments revealed that, compared to the control surface, the surface designs achieved up to a 270% increase in fog harvesting efficiency. The results demonstrate that surface topography and wettability are key factors influencing fog harvesting performance.
