I have been working with cellulose fibrils for over 6 years now, and every day there seems to be new opportunities for this product. It occurred to me the other day that my cleaning product at home contained fairly rough abrasives, enabling me to clean off dirt and stains. In the field of cleaning, this is called “agitation” and is part of the C-H-A-T cleaning formula: Chemical-Heat-Agitation-Time. Could this be something for cellulose fibrils? Let me share with you a couple of my thoughts on where the cellulose fibrils may give you some functionality.
One of the advantages of cellulosic materials (including nanocellulose and microfibrillated cellulose (MFC)) compared to synthetic materials, is their environmentally friendly profile as well as their biodegradability. This profile is impacted by the number of chemical reactions the product will undergo during the manufacturing process. It would therefore be favorable to obtain desired chemical properties via physical adsorption instead of chemical reactions.
In this blog post, you will find examples on possible effects of surface adsorbed surfactants on cellulosic materials.
