1. 1. Chemical modification of regenerated-cellulose films with determined patterns and different regeneration mediums to achieve superhydrophobic properties

   University essay from Mittuniversitetet/Institutionen för kemiteknik

   Author : Pornpan Kongthong; [2021]
   Keywords : Surface roughness; regeneration of cellulose; Regenerated-cellulose; superhydrophobic surfaces; Alkyl Ketene Dimer AKD ; Scanning Electron Microscope SEM and X-Ray diffraction XRD ;

   Abstract : In our modern society there is a need to find a material that is biodegradable to reduce the use of plastic for a greener society. By means of superhydrophobic surfaces there is a possibility to replace plastic with cellulose and use Alkyl Ketene Dimer (AKD) as a sizing agent to make the surface hydrophobic. READ MORE

3. 2. Tuned sustainable anodic coatings for reduced ice adhesion

   University essay from Linköpings universitet/Molekylär ytfysik och nanovetenskap

   Author : Thirza Poot; [2019]
   Keywords : aluminum alloys; tartaric-sulfuric acid anodizing; ice adhesion; silanization; hydrothermal sealing; contact angle; SEM; corrosion;

   Abstract : Aluminum alloys are widely used materials in the aircraft industry due to their high specific strength and durability. The natural corrosion resistance of aluminum can be improved through an electrochemical anodizing process. READ MORE

4. 3. An experimental study of surface coatings to limit the impact of frosting

   University essay from KTH/Energiteknik

   Author : Carl Andersson; [2018]
   Keywords : ;

   Abstract : Heat pumps are commonly used as a way to efficiently meet heating demands. The efficiency and flexibility of Air-source heat pumps (ASHPs) have improved in recent years and is an attractive heating solution suitable for houses with lower heating demands, as it is inexpensive to purchase and install compared to other heating solutions.

5. 4. Superhydrophobic surfaces for microfluidic applications

   University essay from Uppsala universitet/Mikrosystemteknik

   Author : Anton Rundberg; [2018]
   Keywords : resistance; reduction; transparent; reusable; resealable;

   Abstract : The integration and use of superhydrophobic surfaces to microfluidic systems were investigated in this work. Superhydrophobic surfaces are believed to have the ability to reduce the hydrodynamic resistance of a microchannel, reduce the risk of clogging due to reduced liquid contact with the microchannel walls and reduce the losses in a microfluidic system.

6. 5. Turbulent flow control via nature inspired surface modifications

   University essay from KTH/Mekanik

   Author : Miguel Beneitez; Johan Sundin; [2017]
   Keywords : flow control; DNS; lattice-Boltzmann; surface coating; friction drag; surface structures; superhydrophobic; porous; fibers; micropillars;

   Abstract : Many of the flows in nature are turbulent. To modify turbulent flows, nature serves itself with different types of coatings. Sharks have riblets-like structures on their skin, fishes have slime with polymers and the surface of the lotus flower has superhydrophobic properties. READ MORE
