Cellulose fibrils are most often supplied as readily activated water suspensions. This maintains the product’s performance and makes it easy to incorporate into a formulation. It however brings up questions about the microbial stability of the suspension over time. Is the robustness of Cellulose fibrils enough in this case?
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.
Continuously following the world of cellulose fibrils and the development is both dynamic and interesting. A lot of new inventions are taking place, based on the cellulose fibrils. We have given 3D printing a quite high focus in the last couple of reviews, but this week there are two other news items on the list: composites made from cellulose fibrils. Dig into this week’s research review to find out more on what might possibly be the next generation of composite materials.
The performance coatings sector has seen decades of development to protect installations and transportation equipment. The sector has been highly dominated by solvent based systems and these systems have seen incremental innovations for a long period of time. The end-user demands for these systems have been set in a context of a world in an ever-changing environment: high pressure on efficiency, increased globalization and international trade, as well as the period of increased climate focus. So how is this world going to look in the near future? In my attempt to share thoughts on this subject, I will focus on the rheology system, how its currently being solved and how it can be solved with alternative, more environmentally friendly technologies in the future.
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.
Nanocellulose has been a hot topic for several years and numerous applications have been proposed, some of them more potential than the others. The major limitation for the wider use of nanocellulose has been the limited commercial availability. The term nanocellulose, however, covers several different types of nano- and microfibrillated and fibrillar cellulose products. One of those is bacterial cellulose which is also more commonly referred as bio-cellulose. It might come as a surprise for many of us, but bio-cellulose is in fact present in several commercially available products. One of those were the legendary Sony MDR-R10 headphones which were introduced already as early as 1988.
Dust originating from abrasion of dry materials can cause a danger to the health and environment. One of the industries that is paying a lot of attention to dust control is the seed treatment industry. Seed treatments are an essential part of today’s agriculture and it means applying the crop protections products, like insecticides and fungicides, directly on the seeds before planting. This is regarded as an effective way to apply the crop protection products and can reduce the needed amount of the products in total. However, the applied substances can start wearing off from the seeds when they are transported and handled which can cause unhealthy dust.
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.
