  1. 16. Easy-to-clean properties in coatings for automotive applications

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

  3. 17. Surface functionalization of nonwoven polypropylene with BTCA polycarboxylic acid in supercritical carbon dioxide medium

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Md Fahad Khan; [2021]
    Keywords : Nonwoven polypropylene; Supercritical carbon dioxide; Surface functionalization; 1; 2; 3; 4- Butanetetracarboxylic acid; Impregnation; Environmentfriendly; Hydrophilicity;

    Abstract : Nonwoven polypropylene has been utilized broadly in various hygienic and medical textile applications because of its excellent mechanical properties, chemical resistance, and minimal expense contrast with other synthetic polymers. However, the insufficiency of surface tethering groups, including adhesion, wettability, and hydrophilicity, some applications are not convenient on nonwoven polypropylene surfaces such as dyeing, printing, attachment of antibacterial and bioactive agents.

  4. 18. Stretchable Barrier Coatings For Fiber-Based Materials : A laboratory study into the development of extensible/stretchable barrier coatings with nanoclay implementation, focusing on water vapour barrier properties.

    University essay from Karlstads universitet

    Author : Kajin Muradparist; [2021]
    Keywords : Stretchable; Barrier; Coating; WVTR; WVP; Hydroforming; Töjbar; Barriär; Bestrykning; WVTR; WVP; Hydroforming;

    Abstract : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. READ MORE

  5. 19. GIANT UNILAMELLAR VESICLES FOR PEPTIDE-MEMBRANE INTERACTION STUDIES USING FLUORESCENCE MICROSCOPY

    University essay from Linköpings universitet/Biofysik och bioteknik

    Author : Martin Nilsson; [2020]
    Keywords : Giant unilamellar vesicles; Lipid rafts; Fluorescence microscopy; Drug delivery;

    Abstract : Vesicles are a type of biological or biomimetic particle consisting of one or more often spherical bilayers made up of amphipathic molecules, creating a closed system. They can function as an encapsulating device, holding hydrophilic molecules on the inside of the bilayer membrane(s) or hydrophobic molecules in the non-polar interstitial space in the middle of the bilayers.

  6. 20. Development of corrosion resistant coatings using natural biopolymer and pollen

    University essay from KTH/Materialvetenskap

    Author : Alessandro Armani; [2020]
    Keywords : ;

    Abstract : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.
