Abstract
A process for producing a polymer/filler composite material includes a mixture forming step in which there is obtained a mixture of a flake-like filler and a polymer material, and the mean area (L2), mean thickness (d) and volume fraction (c) of the flake-like filler in the mixture satisfy the following equations (1), (2) and (3): 500 nm2≦L2≦100 μm2 (1) d≦L/20 (2) 0.2d/L≦c≦4d/L (3), and a deforming step of applying deformation to the mixture at a strain rate of no greater than 10 s−1.
