Ionic Liquid from China Wood Oil and Analogs Used to Make Self-Healing Polymers

UAH-P-11017-Ionic Liquids Revised-01

Docket: UAH-P-11017


Petroleum-based resins have a huge impact on the environment. There is a need for self-healing bio-renewable alternatives that address the problems of petroleum-based resins.

Researchers at UAH have developed a Drying Ionic Liquid (DIL) that is incorporated in a curable polymer so that when cracks develop the ionic liquid would fill the crack and heal the damage. The DIL developed here is valued for its coatings and is engineered to have electrical conductive properties to form a chemically stable and adherent coating.

The DIL developed here requires no curing agent to polymerize the resin, and it can be done under atmospheric conditions. The low volatility and high thermal stability will ensure that the repair resin will survive the cure of the matrix polymer.
