Abstract
Described herein are self-healing polymers comprising a base polymer and at least one healing agent disposed in the base polymer under pressure.
Claims7
A method of making a self-healing polymer comprising:
- forming a base polymer;
- 3D printing a sacrificial network;
- embedding the sacrificial network in the base polymer;
- and
- removing the sacrificial network from the base polymer to form a vascular network in the base polymer for storing a healing agent in the base polymer;
- randomly dispersing the vascular network throughout the base polymer.

A method of making a self-healing polymer comprising 3D printing a base polymer and simultaneously 3D printing a vascular network in the base polymer for storing a healing agent in the base polymer, and randomly dispersing the vascular network throughout the base polymer.
A method of making a self-healing polymer comprising:
- forming a base polymer;
- 3D printing a sacrificial network;
- embedding the sacrificial network in the base polymer;
- and
- removing the sacrificial network from the base polymer to form a vascular network in the base polymer for storing a healing agent in the base polymer;
- injecting a healing agent into the vascular network under pressure;
- removing air from inside the vascular network prior to injecting the healing agent in the vascular network so that the healing agent is disposed in the base polymer under pressure.
