Cellulose nanocrystals (CNCs) were used to improve the performance of poly(vinylidene fluoride) (PVDF), and thecomposite properties were characterized. The results showed that the prepared nanocomposites displayed the increases in mechanical properties. In particular, with the incorporation of 6wt% CNCs, increases in tensile strength and dynamicstorage modulus were observed. For hydrophilicity, the water contact angle decreased from 90° to 77° with the incorporation of only 3wt% CNCs, indicating improved hydrophilicity. Addition of CNCs to PV...
