Abstract
A self-healing polymer material that includes a multiphase copolymer, and a method of making the copolymer, are provided. The multiphase copolymer includes one or more hydrogen bond-forming copolymer segments, each segment including a polymerized acrylamide monomer and a polymerized acrylic monomer. The polymerized acrylamide monomer includes functional groups that form hydrogen bonds in the multiphase copolymer, and is present in the one or more copolymer segments in an amount sufficient for self-healing of the multiphase copolymer.

A self-healing polymer material comprising a multiphase copolymer comprising one or more hydrogen bond-forming copolymer segments, each hydrogen bond-forming copolymer segment comprising a polymerized acrylamide monomer and a polymerized acrylic monomer, the polymerized acrylic monomer being a methacrylate monomer or an acrylate monomer, or a combination thereof,
- wherein the polymerized acrylamide monomer comprises functional groups that form hydrogen bonds in the multiphase copolymer, and wherein the multiphase copolymer further comprises polymerized styrenic segments forming glassy domains in the multiphase copolymer.
A self-healing polymer material comprising a multiphase copolymer comprising one or more hydrogen bond-forming copolymer segments, each segment comprising a polymerized acrylamide monomer and a polymerized acrylic monomer, the polymerized acrylic monomer being a methacrylate monomer or an acrylate monomer, or a combination thereof,
- wherein the polymerized acrylamide monomer comprises functional groups that form hydrogen bonds in the multiphase copolymer, and wherein the multiphase copolymer is a branched copolymer.
