Description: Nondestructive evaluation of cellulose nanofibril (CNF) films was performed using cantilever beam vibration (CBV) and acoustic methods to measure dynamic modulus. Static modulus was tested using tensile tension method. Correlation analysis shows the data measured by CBV has little linear relationship with static modulus, possessing a correlation coefficient (R2) of 0.282. However, the data tested by acoustic method correlated well with the static modulus, approaching a correlation coefficient of 0.6. Irregular sample shape largely contributed to these obtained results. The dynamic modulus, especially measured by acoustic method, is likely an effective tool in non-destructive evaluation of mechanical properties for CNF nanomaterials.

Keywords: Cellulose nanofibril films, cantilever beam vibration, Acoustic method, tensile test
