elastic modulus of the CNT and the adsorption layer near the CNT contributed to the
size-dependent elastic modulus of the nanocomposites. Using the proposed multiscale
bridging model, the elastic modulus for nanocomposites at various volume fractions
and CNT sizes could be estimated. Among three major factors (CNT waviness, the
dispersion state, and adhesion between the CNT and matrix), the proposed model con-
sidered only the weakened bonding effect. However, the present multiscale framework
can be easily applied in considering the aforementioned factors and describing the
real nanocomposite microstructures. In addition, by considering chemically grafted
molecules (covalent or non-covalent ...
