Important rheological properties of cellulose fibrils / nanocellulose

By Mats Hjørnevik 13. November 2018

Rheology is the study of deformation and flow of material under stress, for example how easily material changes its form when it is pressed, or how easy it is to pump liquid in the pipes. Yield stress and viscosity are two importance aspects in the study of rheology and I will today exemplify this by using the cellulose fibrils/nanocellulose technology.

How to compare rheology additives: the example of nanocellulose/Cellulose fibrils and HEUR

By Mats Hjørnevik 16. October 2018

As a researcher, to have an overview of the alternatives available in your area of profession is of importance. In the landscape of rheology, new alternatives are emerging. In my short review today, I will grasp on the subject of similarities and potential synergies between two of the candidates you should note down: nanocellulose and hydrophobically modified ethoxylated polyurethanes (HEUR). Here are my hints and tips  on how to understand these two technologies better.
