Stability analysis for different grades of Micro-fibrillated Cellulose (MFC) In collaboration with KTH Royal Institute of Technology, Stockholm Sweden

Introduction

Nano-scale cellulose fibre materials (e.g., Micro-fibrillated Cellulose) serve as

a promising candidate for bio-based materials from a sustainable resource

thanks to their abundance, high strength and stiffness, low weight and

biodegradability.

Micro-fibrillated Cellulose is obtained from a fibrillation process in water which

converts cellulose fibres into a volume spanning three-dimensional network of

micro fibrils. As a result, a robust product with interesting rheological properties

is formed. It is well adapted for application fields such as cosmetics, food,

coatings, cements, agrochemicals and nanocomposites…

Characterization of fibrillated celluloses however, remains challenging due to

its heterogeneous nature. MFC mostly consist of long, slender fibril

aggregates with a high degree of branching. Fibrillated celluloses contain

fibrils and fibril aggregates with different dimensions and thus their proper

assessment requires methods adapted for multi-dimensional analysis.
