11. Strategies to improve the aging, barrier and mechanical properties of chitosan, whey and wheat gluten protein films
Abstract : Chitosan, Whey Protein Isolate (WPI) and vital wheat gluten (WG) are three biomaterials that have quite promising properties for packaging purposes. They have good film forming properties and good gas barrier properties in dry conditions. READ MORE

12. Wheat Gluten -Based Materials and Composites: Extrusion, Casting and Antimicrobial Properties
Abstract : The use of bio-based polymers as packaging materials has gained much attention due to increasing environmental concerns regarding non-biodegradable petroleum-derived plastics. Wheat gluten (WG) is a valuable renewable resource for the production of bio-based materials because of its low price, biodegradability, good film-forming properties and good gas barrier properties under dry conditions.

13. Polymer Nanocomposites in Thin Film Applications
Abstract : The introduction of a nanoscopic reinforcing phase to a polymer matrix offers great possibilities of obtaining improved properties, enabling applications outside the boundaries of traditional composites. The majority of the work in this thesis has been devoted to polymer/clay nanocomposites in coating applications, using the hydroxyl-functional hyperbranched polyester Boltorn® as matrix and montmorillonite clay as nanofiller.

14. Electrostatically Driven Structure Formation in Clay Dispersions
Abstract : Clay minerals consist of clay platelets, which are anisotropic in both size and charge, and these can form a lamellar structure depending on the size, making it a seemingly perfect model system for an electrical double layer. The situation is however, from a structural point, slightly less ideal. READ MORE

15. Biodegradable Blends and Nanocomposite Films with Amylopectin, Poly(lactic acid) and Chitosan Matrices
Abstract : Användningan av engångsförpackningar har ökat kraftigt de senaste åren. Den absolut största delen av dessa förpackningar tillverkars av oljebaserade plaster såsom polyetylen (PE) och polypropylen (PP). Dessa har även en oerhört lång nedbrytningstid, vilket gör det viktigt att finna mer miljövänliga alternativ. READ MORE
