COMPOSITE MATERIAL

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 comprised of one or more layers whereby each layer is comprised of a plurality of particles having a predetermined median particle size diameter. The predetermined media particle size in each layer, when viewed in cross section, can form a particle size gradient such that the median particle size of each layer sequentially decreases (or increases) across the cross section of the material. Particles can further be core-shell particles releasing their core material upon actuation.
