  1. 1. A Study on Lignin or Zein Based Hydrophobic Coatings

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Filippa Wentz; Sandra Olofsson; [2023]
    Keywords : Lignin; Zein; Hydrophobic Coating; Dispersion; Chemical engineering; Technology and Engineering;

    Abstract : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. READ MORE

  3. 2. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

    University essay from KTH/Fiber- och polymerteknologi

    Author : Malin Eriksson; [2022]
    Keywords : dispersion coating; paper products; pigment; sustainable development; circular economy; Dispersionsbarriär; pappersprodukter; pigment; hållbar utveckling; cirkulär ekonomi;

    Abstract : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. READ MORE

  4. 3. Erosion Behaviour of Thermal Barrier Coatings

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Caroline Wännman; [2021]
    Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

    Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE

  5. 4. 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

  6. 5. Investigation of graphene and nanocellulose hybrid films as a barrier material in packages

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Jens Bodelsson; [2019]
    Keywords : Nanocellulose; CNF; Graphene; Barrier; Dispersion; graphene nanosheets; coating; sonication; carboxymethylated; polymer technology; polymerteknologi; Technology and Engineering;

    Abstract : In this report, hybrid films of carboxymethylated cellulose nanofibrils (CNF) and graphene nanosheets (GNs) have been prepared to evaluate if the GNs can enhance the barrier properties of the CNF films. CNF already possess great barrier properties at low relative humidity (RH) but it is drastically lowered when the RH reaches above 50% due to its strong hydrophilicity of CNF. READ MORE
