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.

Improving cleaning products: utilizing multifunctionality of cellulose fibrils

By Mats Hjørnevik 31. October 2017

I have been working with cellulose fibrils for over 6 years now, and every day there seems to be new opportunities for this product. It occurred to me the other day that my cleaning product at home contained fairly rough abrasives, enabling me to clean off dirt and stains. In the field of cleaning, this is called “agitation” and is part of the C-H-A-T cleaning formula: Chemical-Heat-Agitation-Time. Could this be something for cellulose fibrils? Let me share with you a couple of my thoughts on where the cellulose fibrils may give you some functionality.

The difference between soluble polymers and cellulose fibrils

By Mats Hjørnevik 24. October 2017

Water soluble polymers have been used for decades, bringing various functionalities to a high number of applications. The reason for their popularity is the ability to being customized by changing molecular weight and molecular chain length, their high efficiency in use (especially the ones with high molecular weight), and their relatively simple handling. However, in certain cases polymeric viscosifiers fail to offer the needed performance and microfibrillated cellulose can offer exactly the desired properties.

Hot in nanocellulose, Oct. 2017: 3D printing and Enhanced Oil Recovery

By Mats Hjørnevik 17. October 2017

As usual, the landscape of cellulose fibrils and nanocellulose is moving, with both academia and commercial producers introducing new concepts and products. This week, I picked up on two distinct stories which I found interesting; VTT in Finland has been working on 3D printing for wound care and decoration, while the Norwegian University of Science and Technology together with the University of Calgary is looking into how the nanocellulose can improve oil recovery rates.

Why sustainable innovations will make our planet healthier; our globe is changing

By Mats Hjørnevik 26. September 2017

2017 has been a year of record storms and hurricanes. In August and September, the hurricanes lined up in the Atlantic and entered into populated areas one after another. The National Oceanic and Atmospheric Administration (NOAA) in the US reports that the statistics show an upward trend, also correlating to the size and magnitude of these hurricanes. The statistical data show uncertainties during the period from 1880s to 2016, but NOAA believes that the trend (based on research) shows a significant increase both in frequency and magnitude going forward. Why do I start my blog post on a nanocellulose blog with this? Well, because the link NOAA put between the Atlantic hurricane trends and global warming is obvious.

Nanocellulose Research Review: Commercial update Sept. 2017

By Mats Hjørnevik 5. September 2017

The field of nanocellulose, fibrils of cellulose and microfibrillated cellulose is moving rapidly in the direction of full commercialization. Still, there are many undescribed application areas that are appearing, with higher and lower levels of innovation. In this week’s review, I am covering two very interesting stories; the increased interest from Japanese motor industry in utilizing the nanocellulose as components for their vehicles, and 3D printing of a nanocellulose alginate product.

The future of Aerospace, and its demand for new materials

By Mats Hjørnevik 25. July 2017

Innovation in aerospace technologies is moving forward with a very high pace. Since the mid-1990s we have seen the birth of much more energy efficient propulsion systems, increased use of advanced materials like carbon fiber, a higher level of adhesives used and improved customer experience through noise reduction. So what’s next on the agenda for all the companies involved? Can we continue to improve the materials or have we started to reach the end of optimization? And are there any new materials coming that could be part of changing the game yet again?
