  • Bio-based and Biodegradable Foams from Wheat Gluten using Up-Scalable Processes
  • 2024
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • In this thesis, the production of bio-based and biodegradable foams from wheat proteins (wheat gluten) is presented. Wheat gluten, a side stream from the ethanol/starch industry, was processed using both batch and continuous foaming methods. To produce the foams, glycerol, an effective protein plasticiser, was used, with two foaming agents common in food: sodium bicarbonate (SBC) and ammonium bicarbonate (ABC), to generate soft foams with both closed-and open-cell structures. ABC proved to be a better foaming agent in foam extrusion than SBC, but SBC performed well in the batch methods. Due to ABC’s low decomposition temperature, extrusion could take place at a temperature as low as 70 °C.     Three different multifunctional additives (citric acid, gallic acid and genipin) were also used to influence and improve the foam properties. The mechanical properties showed that some of the materials could be potentially useful in cushioning and sealing applications. The foams also showed a high absorption of saline (model substance for body fluid) and blood (in the form of sheep’s blood), even under mechanical pressure. Based on these results, a wheat gluten-based product was manufactured as a proof-of-concept.     The degradability of the foam in various relevant environments was studied. It was found that some foams degraded almost completely in soil after 8 weeks and in alkaline water after 5 weeks. It was also demonstrated that the foam also worked as a good fertilizer. As an alternative to direct composting when the foam is no longer used, the possibility of reusing the foam in a different form was evaluated. In this context, it was possible to produce plastic films from the foam.

  • Flexible hybrid organic/inorganic SiOx aerogels via in situ template condensation
  • 2024
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Modern insulation materials such as mineral wool are common but have known health risks. Cellulose-based insulation is an improvement regarding health but is flammable by itself and can settle. Aerogels are an attractive insulation material due to their incredible insulation while also very light, they are made from an abundant non-toxic material (silicon oxide). Several challenges need to be overcome to be viable for common use. Critical point drying is often used which is slow and has a high risk of failure. Further aerogels are brittle where even small deformations result in breaking, limiting their use.This work focused on using graphene oxide, mycelium, or cellulose as organic templates to make organic/inorganic hybrid aerogels by controlled silane condensation.Using graphene oxide (GO) showed that both APTES and TEOS were able to form uniform, smooth silane layers on an organic GO template. It was also possible to remove the GO template without changing the formed silicon oxide material using high temperature. With similar developed condensation conditions, it was possible to form SiOx coatings on bacterial cellulose nanofibrils (bCNF), the choice of silane allowed control over the formed coating morphology, and the modified bCNF dispersion could be freeze-dried into aerogels. To explore the developed coating methodology, another promising insulation material (mycelium) was used as a template. The mimicking of the mycelium hyphae was shown possible, enabling silicon oxide nanofibers after the removal of the mycelium template. Lastly, sol-gel formed organic/inorganic aerogels were developed, using bCNF as a toughening matrix, enabling high flexibility without crack formation or shattering even after significant deformation. The aerogels were thermally stable, flexibile, and avoided critical point drying allowing for large-scale aerogel production.
