Trouble with cracking during drying of your coating, adhesive, putty or other products?

By Mats Hjørnevik 22. May 2018

One of my favorite characteristics of the cellulose fibrils is its behavior when drying or involved in the drying process of a product system. I have learned through some of our conducted tests that cellulose fibrils can act in an interesting and often beneficial way towards obtaining desired end product characteristics. Most of the examples on how the fibrils influence the drying are related to coatings. I however believe that similar behavior is possible to observe in application areas where a tight control of dry-out properties is desired. Evaporation of solvents is often the main technique for drying in many applications. I will therefore focus my blog post this time on this specific drying technique. Let me share some very interesting insights into why cellulose fibrils are improving the products upon drying.

How to improve art conservation by utilizing the technology advantage

By Mats Hjørnevik 15. May 2018

OK, so this case fascinated me a great deal. I have previously learned a lot on film forming properties, oxygen barrier properties and other related topics to this in the past. But recently I learned that the properties from microfibrillated cellulose and cellulose fibrils is starting to show potential in art preservation or conservation. But how does this take place, and what’s the main functionalities behind all this? I spent some time researching the subject, and today I am sharing my findings with you. Some key words: stability, transparency and mechanical strength. Dig in to learn more!

Nanopaper preparation with KTH

By Anastasia Riazanova 1. May 2018

Making nanopaper is an good test on the characteristics of cellulose fibrils, and especially strength and durability. In this weeks blog from the Exilva blog, our H2020 partners at KTH are showing you how to make the nanopaper in a "step-by-step" practical example. The making of nanopaper quickly illustrates the strength performance you can get from this material once it forms paper or film. Spend a couple of minutes, and you will quickly understand why this material can take a leading part in the dual focus of increased sustainability and performance.

Acoustic and dielectric properties of nanocellulose

By Otto Soidinsalo 13. March 2018

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 control with cellulose fibrils

By Anni Karppinen 6. March 2018

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.

Cellulose fibrils for immediate skin anti-wrinkle effect

By Rebecca Blell 23. January 2018

There are many different solutions for reducing wrinkles and age marks on the skin. These range from long term permanent treatments of the skin to formulations that have immediate, temporary and only optical effects on the skin. In most formulations and products, a combination of a permanent solution with an immediate effect is desired.

In this blog post, I will introduce the terms “anti-aging”, “anti-wrinkle effect”, “immediate anti-wrinkle effect” and follow up with a few points explaining why cellulose fibrils can potentially give an immediate skin anti-wrinkle effect.

Shifting paradigms: introducing alternative technologies

By Mats Hjørnevik 9. January 2018

This week’s blog post started its life when I attended a stakeholder forum which was organized by the Bio-Based Industries Joint Undertaking (BBIJU), a part of the EU H2020 initiative. I listened to a high number of innovators within several fields such as bio-fuels, bio-chemicals, as well as new and more sustainable materials. I started a line of thought, where the word paradigm occurred to me; I am part of a generation raised in the latter part of the 20th century where a majority of things we take for granted are based on technologies from the petroleum sector. The paradigm has given opportunities and challenges, but how does this paradigm affect us and our thoughts on innovation?

What has cellulose fibrils to do with air quality?

By Otto Soidinsalo 3. October 2017

You might have noticed how the air quality around us is changing constantly. Do you remember the last time that you have filled your lungs with fresh and clean air? Every day we are exposed to pollutants in the air we breathe - chemicals as well as fine particles - whether we are staying outdoors or indoors. This problem not only affects the people in developing countries, but the majority of the population on Earth.

The role of MFC in flexible displays and electronics

By Otto Soidinsalo 1. August 2017

The transformation from cathode ray tubes to LCD displays has been rapid since the early 2000s. We now have thinner, lighter and bigger screens available with affordable prices. You have probably also seen pictures of flexible displays and read stories about flexible mobile phones and foldable screens. I'm sure many of you have also thought if we really need those and would it in the end be practical to have a foldable display in your pocket. Probably not, but flexible displays allow new product opportunities for many industries such as car industry and consumer products. However, one of the biggest drivers for the flexible displays is actually related to the manufacturing of the displays.
