Cellulose Nanocrystals With Enhanced Thermal Stability Reinforced Thermoplastic Polyurethane

Melt compounding processing approach for incorporating cellulose nanocrystals (CNC) into thermoplastic polyurethane (TPU) has not well been explored. This is primarily due to the poor thermal stability and dispersibility of CNCs. As they are typically obtained from sulphuric acid hydrolysis, they gi...
