Ceramic-Like Thermal Expansion Obtained from Cellulose Nanocrystal Films
Snapshot: One of the unique properties of cellulose nanocrystals (CNC) are their low dimensional change with changes in temperature. Understanding the role and mechanism associated with thermal expansion within CNCs and CNC composites is important to a variety of fields. Forest Service researchers developed a unique characterization technique using polarized light imaging correlation that allows more accurate coefficient of thermal expansion measurement of thin transparent CNC films.
