The leading blog on nanocellulose
Having demonstrated the viscosity stabilizing effect of Exilva in starch adhesives, for this third blog post in the corrugated boards application series, I will focus on the effect on glue ability and production speed.Read more
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.
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.
Wound dressings are advanced materials designed for securing sufficient healing of exterior wounds. These dressings have been around for a while, often containing hydrocolloids to be able to protect and absorb moist as well as increase the wound healing speed. I will give you a short overview of what types of wound dressings that are available and how microfibrillated cellulose (MFC) may give a new addition to this field of technology.
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.
Can MFC assist formulators of car care products achieve the next level of performance? Can it offer ease of use for consumers and car care professionals, while at the same time using safer, more environmentally friendly additives with a wide range of functionality? I think the answer is yes, and I will show you why.
Microfibrillated cellulose (MFC) differs from many rheology modifiers in that aspect that it can be used in high salinity formulations. The rheology effect comes from entangled fibers and salts do not influence this network as it does when the rheology effect is based on ionic interactions. However, the viscosity and other rheological properties vary slightly as a function of salt concentration. Let’s take a closer look at the reasons behind this.
Three dimensional (3D) printing and tissue engineering are two fields that are currently developing rapidly and are both exciting technologies on their own. What if you combine them? That creates a new manufacturing process, bioprinting. It is a promising technology that might be the key to the on-demand tissue engineering. Microfibrillated cellulose (MFC) or nanocellulosic materials generally have an important role in the development.
Oil recovery with all different operations is a fascinating field for a rheologist since so versatile rheological properties are required in the processes. Microfibrillated cellulose has been recognized as potential green, safe rheology modifier for the oil recovery industry. Why is that?
The biggest change in the coffee culture in recent years has been the way people prepare their coffee at home. An increasing number of households use single serve brewing (pods, capsules) for producing a fresh cup of coffee, resulting in an increased amount of waste. Replacing the current coffee packing materials is not straightforward, and obviously there are several challenges related to it. In this blog post I will play with the idea how microfibrillated cellulose (MFC) could support the development of new, more environmentally friendly, compostable or biodegradable coffee capsules.
