1. 11. 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.

   Master-uppsats, Karlstads universitet

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

   Sammanfattning : 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. LÄS MER

3. 12. Experimentell studie av egenskaperna av protein-baserat plast

   M1-uppsats, KTH/Fiber- och polymerteknologi

   Författare :Muhamed Mahmutovic; [2020]
   Nyckelord :biobased; protein; plastics; film; plasticiser; biobaserad; protein; plast; film; mjukgörare;

   Sammanfattning : På grund av ökad användning av plast har biobaserade polymerer som förpackningsmaterialfått stor uppmärksamhet de senaste åren på grund av miljöhänsyn. Flera proteinmaterial, t.ex.vetegluten har varit i fokus för betydande forskning kring ny biobaserad plast och resultatenär lovande. LÄS MER

4. 13. A novel chitosan-stearic coating with bee-pollen microcapsules for corrosion protection

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Albin Andersson; [2020]
   Nyckelord :;

   Sammanfattning : In this project a novel chitosan-stearic acid (CS-SA) coating with bee-pollen microcapsules for encapsulation of 2-mecraptobenzothiazole (MBT) as a waterborne formulation for a biocompatible corrosion protection coating was developed and the coating properties was analyzed. Hydrophobic stearic acid (SA) was crosslinked with via a carbodiimide reaction to form micelles and is assembled on the bee- pollen grains and the chitosan matrix was further self-crosslinked using glutaraldehyde (GA).

5. 14. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

   Författare :Joel Johansson Byberg; [2019]
   Nyckelord :CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

   Sammanfattning : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.

7. 15. Applicability of bio-based polymer packaging in the meal kit context - A case study with HelloFresh

   Master-uppsats, Lunds universitet/Förpackningslogistik

   Författare :Theresa Stolberg; [2019]
   Nyckelord :bio-based polymer; bio-plastics; compostability; food packaging; sustainable packaging; Agriculture and Food Sciences; Technology and Engineering;

   Sammanfattning : Bio-based plastics are increasingly considered as sustainable alternatives to fossil-based plastics. Up until now, their application in the food packaging industry has been limited. LÄS MER
