Bio-based is on everyone's lips these days, and there are a high number of initiatives going on in innovating new product systems with a bio-based background. In this post I will give you a sneak peak into the improvement of an organic solvent system, using a biobased addtive as an example. Cellulose fibrils is a green and environmentally friendly material that consists of a complex three dimensional network of cellulose microfibrils.
It is well known that cellulose fibrils , because of its high surface area and many available hydroxyl (OH) groups, has a high affinity for water. This result in a material with very high water holding capacity that forms strong gels in water at low concentrations. Since cellulose fibrils is so fond of water, it might be easy to think that the material would not perform well if it was dispersed in other solvent systems. However, this is far from the truth!
