  1. 1. Multifunctional ice and snow repellent coatings for photovoltaic modules

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Gunnar Sandkvist; [2023]
    Nyckelord :sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

    Sammanfattning : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. LÄS MER

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

    Kandidat-uppsats, Mittuniversitetet/Institutionen för kemiteknik

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

    Sammanfattning : 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. LÄS MER

  4. 3. Easy-to-clean properties in coatings for automotive applications

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Weyni Ghebreamlak; [2021]
    Nyckelord :Easy-to-clean surface; sol-gel; superhydrophobicity; superoleophobicity; nanoparticles; Lätt-att-rengöra yta ”Easy-to-clean” ; sol-gel; superhydrofobicitet; superoleofobicitet; nanopartiklar;

    Sammanfattning : En ”lätt-att-rengöra” yta definieras som en yta som stöter bort vatten och smuts. I detta projekt har klarlack med olika sammansättningar studerats i syfte att introducera egenskapen ”lätt-att-rengöra”. För att uppnå denna egenskap måste beläggningen vara superhydrofob och oleofob. LÄS MER

  5. 4. Tuned sustainable anodic coatings for reduced ice adhesion

    Master-uppsats, Linköpings universitet/Molekylär ytfysik och nanovetenskap

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

    Sammanfattning : 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. LÄS MER

  7. 5. An experimental study of surface coatings to limit the impact of frosting

    Master-uppsats, KTH/Energiteknik

    Författare :Carl Andersson; [2018]
    Nyckelord :;

    Sammanfattning : 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.
