Abstract
Disclosed herein are composites capable of self-repairing. In some examples, the composites include a binding medium and a plurality of binding medium-repairing particles. The binding medium-repairing particles disclosed herein comprise a reactive agent encapsulated in a shell, where the reactive agent can interact with the binding medium to form an aggregate in the presence of an aqueous medium. Also disclosed herein are methods for making the composites and methods for making the binding medium-repairing particles.
Claims24
A binding medium-repairing particle, comprising:
- a reactive material comprising a reactant and an adhesive material, wherein the adhesive material is water soluble;
- and
- a shell configured to at least partially encapsulate the reactive material,
- wherein the reactant is selected to interact with a binding medium to form an aggregate in the presence of an aqueous medium.
A self-repairing composite, comprising:
- a binding medium;
- and
- a plurality of particles, wherein at least one of the plurality of particles comprises a reactive material comprising a reactant and an adhesive material, and a shell configured to at least partially encapsulate the reactive material, wherein the reactant is selected to interact with the binding medium to form an aggregate in the presence of an aqueous medium, wherein the adhesive material is water soluble.
A method for making binding medium-repairing particles, wherein the method comprises:
- providing a reactive material, wherein the reactive material comprises a reactant and an adhesive material, wherein the reactant is selected to interact with a binding medium to form an aggregate in the presence of an aqueous medium, and wherein the adhesive material is water soluble;
- pelletizing the reactive material to form particles;
- and
- coating the particles with a shell to make the binding medium-repairing particles.
A method for making a self-repairing composite, wherein the method comprises:
- providing a reactive material, wherein the reactive material comprises a reactant and an adhesive material, wherein the reactant is selected to interact with a binding medium to form an aggregate in the presence of an aqueous medium, and wherein the adhesive material is water soluble:
- pelletizing the reactive material to form a first plurality of particles;
- coating one or more of the first plurality of particles to form a second plurality of coated particles;
- mixing one or more of the second plurality of coated particles with the binding medium to form a mixture;
- and
- curing the mixture to form the self-repairing composite.
