Long-term stability and aging of cellulose nanofibril dispersions

Cellulose nanofibrils (CNFs) are known to form associative structures even at very low concentrations; however, the fundamental mechanisms governing their assembly and the associated time scales remain poorly understood. Although significant research efforts are underway in this field, systematic, long-term investigations into the stability of CNF dispersions are still lacking. The aim of this project is to conduct a systematic, long-term study of CNFs with different charge densities and surface charge types to provide insights into the mechanisms and kinetics of fibril association at low concentrations.
