摘要: Disclosed herein are engineered composite materials suitable for applications that can benefit from a composite material capable of interacting with or responding to, in a controlled or predetermined manner, changes in its surrounding environment. The composite material is generally includes a gradient layer structure of a sequence of at, e.g., three or more gradient-contributing layers of microscale particles, wherein a mean particle size of particles of neighboring gradient-contributing layers in the cross section of the gradient layer structure varies from layer to layer, thereby forming a particle size gradient, and in contact with the gradient layer structure, a densely packed particle structure including densely packed microscale particles, wherein a mean particle size of the densely packed microscale particles does not form a particle size gradient in the cross section of the densely packed particle structure.
