Recently, an intense research activity is ongoing within the field of cellulose nanofibrils (NFC) and cellulose microfibrils (MFC). The widespread interest can be explained by a few advantageous basic properties, i.e. high availability as a renewable material, high mechanical strength, large specific surface area and high aspect ratios, barrier properties, dimensional stability, biodegradability and biocompatibility (Eichhorn et al. 2010). The objective of this study was to examine the effect of different cellulose nanofibrils (CNF) on the flocculation of precipitated calcium carbonate (PCC).Of particular interest was the study of how the fineness of CNF affect its flocculation.It is probable that the presence of polyelectrolytes can strengthen and induce formation of CNF/polyelectrolyte bridges between filler particles, leading to efficient flocculation |
