How to improve your organic solvent system with a bio-based alternative

By Mats Hjørnevik 12. June 2018

Bio-based is on everyone's lips these days, and there are a high number of initiatives going on in innovating new product systems with a bio-based background. In this post I will give you a sneak peak into the improvement of an organic solvent system, using a biobased addtive as an example. Cellulose fibrils is a green and environmentally friendly material that consists of a complex three dimensional network of cellulose microfibrils.

It is well known that cellulose fibrils , because of its high surface area and many available hydroxyl (OH) groups, has a high affinity for water. This result in a material with very high water holding capacity that forms strong gels in water at low concentrations. Since cellulose fibrils is so fond of water, it might be easy to think that the material would not perform well if it was dispersed in other solvent systems. However, this is far from the truth!

Why should I use cellulose fibrils in coatings?

By Mats Hjørnevik 17. April 2018

It is important for producers of coatings to control flow and stability. The way to do this in water borne systems has typically been a work for synthetically derived additives, water-soluble cellulose derivatives or clays. Can cellulose fibrils do anything new for you?

Microfibrillated cellulose, cellulose fibrils or nanocellulose?

By Anni Karppinen 10. April 2018

Is microfibrillated cellulose (MFC) the same as nanocellulose? What is the difference between micro- and nanofibrillated cellulose? What about cellulose nanocrystals and cellulose fibrils? Starting to read about MFC (or nanocellulose) might be confusing since the terms used for nano- and micro-sized cellulosic materials are versatile. Moreover, they are not totally established, so the same material can have different names or the same terms can be used for very different kind of materials. In this post, I will introduce the most common terms and distinguish synonyms from different materials.

Topic Tuesday: A talk with one of the pioneers in nanocellulose and cellulose fibrils

By Mats Hjørnevik 27. February 2018

Dr. Julien Bras from the Grenoble Institute of Techonology has been working in the field of cellulose fibrils, nanocellulose and microfibrillated cellulose for two decades. He is considered as one of the pioneers on the concept as we know it today. In this 5 minutes chat with Dr. Bras, we touched upon several topics regarding this new material. Do not miss out on the opportunity to listen in to Dr, Bras ideas one some of the directions the cellulose fibrils and nanocellulose will be taking in the future.

Why cellulose fibrils is a completely new cellulose product

By Mats Hjørnevik 20. February 2018

Cellulose fibrils has been present in the academic sector since the 1980’s, but it is completely newborn in a commercial sense. I experience from time to time that the mix up between cellulose fibrils and soluble cellulose (polymers) can create issues in understanding the full potential of the fibrils within a formulation. In this blog post I will try to give you a brief overview of why cellulose fibrils is quite different from the other types of cellulose products as you have learned to know them.

Water holding capacity - how cellulose fibrils does it

By Anni Karppinen 12. December 2017

Water holding capacity, or high water retention value, is often mentioned as a key property of cellulose fibrils. When it is dispersed into water, the fibrils trap water between them and do not release it easily. As a consequence, even rather low concentration of MFC in water has gel-like appearance since the water is not able to flow freely. What is behind this? Let’s try to find out.

Montmorillonite Clay (Bentonites) and cellulose fibrils

By Mats Hjørnevik 21. November 2017

Montmorillonite (Bentonite) clay and cellulose fibrils has a lot in common since they both can be used as a rheology modifier in different industries. However, there are also clear distinct differences. I aim to show you how I reflect on these two product technologies, and how you can look for synergies and new innovations when using cellulose fibrils and clay. I will first review the non-soluble nature which is common for these materials and then show how this is reflected in the rheology and stability properties of each. I will also focus my discussion on the bentonite branch of montmorillonite clays due to its similarities with the cellulose fibrils

Dispersion of Cellulose fibrils – a critical success factor

By Mats Hjørnevik 7. November 2017

Traveling around talking about cellulose fibrils for the past 6 years, has thought me an important lesson; always make sure that people understand how to disperse the fibrils sufficiently. This is really the main factor in gaining the key functionalities from the product. So how can you make sure that you are getting the most out of the cellulose fibrils when you are using it in your formulation? In this article I will give you some guidance and video tool on to how to get this right from the start.
