N2 - Cellulose nanocrystals (CNCs) are rod-like and highly crystalline nanofillers reinforcing polymer matrices because of their high aspect ratio, high surface area, and great Young's modulus. However, there is no simple methodology estimating the Young's modulus of polymer CNC samples. In this study, Young's modulus of polymer composites containing CNCs is predicted using a simple model. This model is validated by some experimental results of various samples. Young's modulus calculations by this model agree with measured values. Moreover, the effects of various factors such as interphase thickness, volume fraction of interphase regions, densities of polymer matrix and CNC, and CNC size on the Young's modulus of samples are examined by the current model. Thinner CNCs significantly improve the Young's modulus of polymer nanocomposite (PNC). Furthermore, thicker interphase causes a higher Young's modulus. Among the mentioned parameters, CNC radius and interphase thickness have the most important effects on the nanocomposite modulus, while the volume fraction of interphase areas causes the least influence.
