摘要:
A composite material includes a polymeric layer and a substrate, in contact with the polymeric layer. The substrate includes a substrate matrix, a first microfluidic network in the substrate matrix and in fluid communication with the polymeric layer, and a polymerizer in the first microfluidic network. The composite material may further include an activator, and may be a self-healing composite.
摘要:
A composition includes a plurality of capsules, and a polymerizer in the capsules. The capsules have an average outer diameter less than 10 micrometers. The capsules can be made by sonicating an emulsion to form a microemulsion, where the emulsion includes water, a surfactant, a first polymerizer and a second polymerizer, and then polymerizing the first polymerizer. The capsules may be present in a composite material that includes a polymer matrix and an activator.

A composite material comprises (i) a polymer, (ii) a polymerizer, (iii) a protected corresponding activator for the polymerizer, and (iv) a plurality of capsules. The polymerizer is in the capsules, and the corresponding activator is protected with a corresponding encapsulant for the polymer and the polymerizer.

摘要:
A composite material includes a polymer matrix, a polymerizer, and a plurality of capsules containing a corresponding activator for the polymerizer. The composite material can also include an adhesion promoter, and the polymerizer can be phase separated from the polymer matrix. The composite material can be made by dispersing the polymerizer and capsules into the polymer matrix. These composite materials can exhibit improved environmental stability, and can be used with a wider variety of activators.
摘要:
A self-healing coating includes a polymer matrix, a polymerizer, and a set of capsules containing a corresponding activator for the polymerizer. The polymerizer may be present in another set of capsules, or the polymerizer may be phase separated from the polymer matrix. The coating may be prepared by depositing a coating composition on a substrate and solidifying the coating composition, where the coating composition includes the polymerizer, the activator capsules and a matrix precursor. A combination of polymerizer capsules and activator capsules may be part of a kit, which may be used to provide self-healing properties to a coating. The polymerizer and the activator may be wet-curable, and coatings containing the polymerizer and activator may be able to self-heal when in contact with water.
摘要:
A composite material includes a solid polymer matrix, a plurality of capsules and a liquid, in the capsules. The liquid includes from 50 to 100 wt% of a solvent, and from 0 to 50 wt% of a polymerizer. There is no polymerizer outside of the capsules. The solid polymer matrix may include a native activating moiety for the polymerizer. The solvent may have a swelling ratio with the solid polymer matrix of at least 1.1 and/or may have a polarity ET of from 0.10 to 0.50.
