Mu-Rong Wang

PhD project

 Functionalization and performance of nanocellulosic filaments

Main supervisor: Daniel Söderberg
Co-supervisor: Anastasia Riazanova, Tomas Rosén
Planned year of defense: 2025

Research interests

I am working currently on chemical and mechanical modification on nanocellulose fibrils(CNFs) in order to tune the CNF network in the flow and to spin strong bio-based filaments. From CNF dispersion to applications:

  • Trying out different sources of cellulose and process them into CNFs. Characterising the differences between the single fibres and the spinning filaments.
  • Studying the correlations between the dynamic behaviour of the CNF network in the flow to the spinnability of CNF dispersions.
  • Conditioning the drying process of bio-based filaments and the interactions between the CNF fibres.
