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?
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.
Never heard of Cellulose Fibrils? Don't worry, I will guide you through the things you need to know. Cellulose fibrils is a completely new performance additive made from natural raw materials, designed to outperform current oil-based technologies. I will during this article give you a quick overview of what cellulose fibrils is, its characteristics and functionalities, and what you can do with it.
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.
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.
Yet another year in the name of innovating with cellulose fibrils has gone by. And again we are thrilled over the engagement and response our readers has shown and given us. As we continue to learn more on these amazing fibrils, we will make sure you are the first to know, also in 2018. While waiting, here are the top 10 most read blog posts in 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 (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
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.
As a new boy in the world of cellulose fibrils, I am steadily getting an overview of what potential users of cellulose fibrils are interested in. The unique combination of properties that cellulose fibrils has is the obvious point most are interested in. In addition, the natural and renewable aspect to the material and the possibility to replace oil-based chemicals is becoming more and more important. But could there be more than that?
