Master Thesis Project - Producing the biobased films of tomorrow
Today's society is increasingly demanding that the materials we use must come from renewable sources and have as little impact on the environment and climate as possible. Above all, harsh criticism is directed at plastics, which usually come from fossil raw materials and take a very long time to degrade in nature. A renewable material that has been shown to have many exciting properties and could compete with plastics in many areas is nanocellulose and more specifically nanocellulose films. These films could be used for future bio-based electronics, hygiene products and packaging to name a few areas. Unfortunately, there is no cheap and efficient manufacturing process for these films available yet. In the lab, it takes several days to produce the films because a lot of water must evaporate (up to 250 times more water than nanocellulose is often used).
Therefore, in this project we want to focus on understanding when it is possible to squeeze out water and when you can suck out water from the wet nanocellulose films. If one can understand how the water can be removed by means other than evaporation, then the film making process could be made both much faster and much cheaper. Which, in turn, would be a large step towards bringing nanocellulose films into the market.
The thesis will include experimental work with filtration, pressing and characterisation of varying nanocellulose types. Suitable models will be adapted to evaluate the experimental data.
We are looking for a student with physics, chemistry, or materials engineering background with laboratory work experience. You will be working alongside researchers from both RISE and KTH at the forefront of the research of biobased materials from the forest.
Location and date
The thesis projects will be performed at RISE’s Smart Materials unit situated close to KTH/Royal Institute of Technology, Stockholm. This project work can start upon agreement, however, latest in September 2023.
