This weeks topic is a follow-up from our last Topic Tuesday. Then we talked about the shear thinning properties of cellulose fibrils. Now, we show you the recovery effect and properties - the thixotropy - of the cellulose fibrils back to its original viscosity. With practical examples!
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.
I stumbled over an article the other day, grasping the opportunity that’s emerging in relation to making electronics based on cellulose sources. The world around us is in an exponential pace making innovations in electronics. So I asked myself the question after reading the article I in this blog post will refer to: can we make smarter electronics with paper-based versions?
Temaer: MFC reviews
Cellulose fibrils has shown great potential as an oxygen barrier in packaging. This has led to numerous research projects trying to utilize the potential in practice. But how does the fibrils actually create the barrier towards oxygen?
We are back with another Topic Tuesday, and today's easy digestible 4 minutes of fame will introduce you to one of our favorite topics: the rheology behavior of cellulose fibrils. Jump on board, as we dig into the shear thinning properties and show you some real life examples.
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.
Plastic microparticles found in the environment have gotten a lot of attention lately. Many of the plastics are very durable and do not degrade in a reasonable time in the nature, although today there are also biodegradable plastics available. Small pieces of plastic can be found almost everywhere on the Earth and it is not fully understood what kind of consequences that could have for the human beings and environment. Therefore, replacing non-biodegradable plastics with biodegradable materials in packaging, clothes and cosmetics has high focus right now. Cellulose fibrils come from wood or other natural resources; are they biodegradable? Can they replace non-biodegradable plastic and reduce the amount of microplastics in the environment?
Once again, welcome to Topic Tuesday, brought to you by the Exilva Blog. Topic Tuesday is dedicated to one specific topic, providing you with information on cellulose fibrils straight from the top of our head. Today we will introduce you to cellulose fibrils' compatibility and performance with various solvents.
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
Welcome to the first of our brand new video series; Topic Tuesday, brought to you by the Exilva Blog. Topic Tuesday is dedicated to one specific topic, providing you with information on cellulose fibrils straight from the top of our head. We'll kick it all of with a discussion about the importance of correct dispersion and how the effect of tip speed affects the end result.
