The leading blog on nanocellulose
The last few years have seen a very fast increase in the use of biologicals and biocontrol agents in crop protection and agricultural products as part of the shift towards more sustainable and environmentally friendly agriculture.Read more
It has been an amazing first year for The Exilva Blog and we’ve been proved that the entrance of Microfibrillated Cellulose in a commercial way, excites a massive group out there. We are already more than eager to start the New Year and share more of our experiences, knowledge and ideas with you. First, let us wrap up the first year of blogging with a top 10 Special Edition.
Cellulose is a renewable and sustainable material and is one of the most abundant natural polymers on earth. Traditionally, cellulose materials have been sold either as a material at the fiber level or as modified celluloses at the molecular level. Currently, there is a high interest in utilizing the full potential of cellulose, and development and commercialization of cellulose materials possessing other structural dimensions are continuously progressing. Microcrystalline cellulose (MCC) has been used commercially for decades. In recent years, the scientific work has focused mainly on two different types of celluloses; microfibrillated cellulose (MFC) and nanocrystalline cellulose (NCC).
In this blog post, I will give you some insight into the differences and similarities between two of these cellulose families; Microfibrillated cellulose (MFC) and Microcrystalline cellulose (MCC). In a continuation blog post coming next week, I will compare MFC and Nanocrystalline cellulose (NCC).
A lot is happening in the world of microfibrillated cellulose and nanocellulose these days. One hot topic is new, engineered materials with MFC. As an example, our blog post on safer batteries with MFC sees a lot of interest, and the ability for MFC to enter into composite materials is an expanding field. In this week’s post, I will try to give you an update on what’s happening with MFC (and nanocellulose) out there, with a focus on the interesting application fields of materials/composites and water purification.
Developing a new kind of material is fascinating work and requires many innovations before the product is available for the market. One important part of the development work is to find analysis methods t for characterizing the quality. Those methods should ideally describe the material well but also be reproducible and reliable. Often this is ensured by using standard methods, but for new materials, like microfibrillated cellulose (MFC), they do not exist yet. Even though some work has been initiated by Canadian Standards Association (Z5100-14 Cellulosic nanomaterials – Test methods for characterization) and TAPPI, there are no proper guidelines for analysis of MFC yet. As a guidance to those unfamiliar with microfibrillated cellulose, I will share my tips for a reliable, reproducible analysis of MFC.
Microfibrillated Cellulose (MFC) is known for its high surface area and large amount of available functional OH groups that provide an outstanding chemical and physical interaction. In addition, due to the strong 3D network, MFC gives a new dimension of stability to various formulations like adhesives, coatings, emulsions, dispersions and so on. In our previous articles, we have already talked about different benefits of using MFC, such as open time or spraying thick formulations. With paints and coatings, the ability to control light transmission and reflection is important. Now your next question is: How can MFC affect this in any way? Follow me and let’s find out!
On the Exilva blog, we will on regular basis bring you selected news from the latest application research both by the industry as well as academic sources. In this blog post, I’ve picked two examples from recently published patent applications, representing the use of MFC in material science and biomedical applications.
Sustainability is a widely used concept, but it is critical to understand what it means and that it is more than just a bunch of production data or a waste reduction plan. Cradle-to-cradle thinking is necessary. The whole life cycle, the production, the use and the disposal of the end product matters.
Microfibrillated cellulose (MFC) is based on one of the most abundant natural resources on earth. Cellulose, the raw material for MFC, is the main structural component in all plants. Its versatility in both sourcing and use gives a perfect opportunity to create new and exciting solutions. To understand the perspective of sustainability and MFC, I will put cradle-to-cradle thinking in the setting of life cycle assessment (LCA).
Microfibrillated cellulose (MFC) is subject to high interest from both academia and the industry these days. A lot of exciting research is being conducted at various universities and research centeres around the world. In this blog post I will review articles I found particularly interesting regarding the use of MFC in adhesives and coatings. Note that, for the sake of simplicity, I have used the term “MFC” throughout this text even if the researchers might have used a different name in their articles.
Microfibrillated cellulose (MFC) has potential as a multifunctional additive in various applications. Its performance ranges from improving stability and flow properties in coatings and adhesives to giving immediate anti-wrinkle effect in skin creams. We often say that, in addition to these effects, one of the other advantages of using MFC is that it is “readily activated”. But what does that mean?
In the exiting field of microfibrillated cellulose new usage opportunities are constantly emerging. During the first quarter of 2016, we have seen many interesting new usage areas, and I will show you a selection of them in this article.
