Abstract
Systems and methods are described in which composite solids such as dyed fibers or fabrics are produced by reversibly generating permeable regions within a heterogeneous solid. Permeating substances are trapped within the heterogeneous solid on reversal of the permeability to form a composite solid, within which the permeating substances are protected from environmental factors.
Claims20
A method for infiltrating a substance into a heterogeneous solid, comprising;
- providing a permeating substance and a heterogeneous solid, the heterogeneous solid comprising a first region, a second region, and an interface region interposed between the first region and the second region;
- applying an energy to the heterogeneous solid, the energy of an amount sufficient to render the interface region temporarily permeable;
- applying a driving force configured to infiltrate the permeating substance into the interface region;
- and,
- modifying the application of the energy, thereby rendering the interface region impermeable.
2 more elements
The method of claim 4, wherein the heterogeneous solid comprises a fiber.
A composite solid, comprising;
- a heterogeneous solid comprising a first region, a second region, and an interface region interposed between the first region and the second region;
- and
- a permeating substance lying within the interface region, wherein the permeating substance is introduced into the interface region by applying an energy configured to render the interface region temporarily permeable.
