Image of FIG. 1.
FIG. 1.

Pair correlation functions of PNC with 5 vol. % nanorods. The solid lines correspond to ɛ = 3.0 and dashed ones relate to ɛ = 1.0.

Image of FIG. 2.
FIG. 2.

Variation of nanorod orientations during deformation and relaxation process at different polymer−nanorod interactions ɛ.

Image of FIG. 3.
FIG. 3.

Variation of nanorod orientations during deformation and relaxation process with different cross-linking densities at (a) ɛ = 1.0, (b) ɛ = 3.0, and (c) ɛ = 5.0, respectively.

Image of FIG. 4.
FIG. 4.

(a) The stress−strain curves of PNCs with different cross-linking densities at ɛ = 3.0. (b) The diffusion coefficient of terminal beads in the nanorod as a function of cross-linking density at different polymer−nanorod interaction in relaxation process.

Image of FIG. 5.
FIG. 5.

Potentials of mean force of nanorods at initial stage and equilibrium stage of relaxation process with (a) ɛ = 1.0 and (b) ɛ = 3.0.

Image of FIG. 6.
FIG. 6.

Snapshots of nanorod network under (a) undeformed, (b) low deformed, and (c) high deformed conditions, respectively. The 13-mer PNCs with 5 vol. % at ɛ = 3.0 are chosen. The red nanorods belong to the main cluster and the grey ones do not belong to the main cluster but can form some small clusters. For clarity, polymer chains are not shown.

Image of FIG. 7.
FIG. 7.

The homogeneous probabilities (a) and homogeneous normalized probabilities (b) of PNC as a function of filler volume fraction with different aspect ratios of nanorods. The draw ratio λ is fixed to 1.0 for the calculation of normalized probabilities.

Image of FIG. 8.
FIG. 8.

Homogeneous normalized probabilities and directional normalized probabilities of PNC as a function of draw ratio.

Image of FIG. 9.
FIG. 9.

The main cluster size and the total number of clusters as a function of draw ratio.

Image of FIG. 10.
FIG. 10.

Schematics of network before deformation (a), under low deformation (b), and under high deformation (c).
