  • Multiple stage curable polymer with controlled transitions
    Patent number: 9550845
    Abstract: The invention provides a polymer system, including a first composition and a second composition. The first composition is different from the second composition. The first composition includes a first gelator, the first gelator including a plurality of acylhydrazine moieties. The second composition includes a second gelator, the second gelator including a plurality of formyl moieties. At least one of the first composition and the second composition includes a prepolymer. The invention further provides a method of using the polymer system to form a polymeric material via multiple stages to more effectively control the rheology of the components over a variety of timescales.

  • Self-healing polymers
    Publication number: 20060252852
    Abstract: 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.
