Reversibly heat stiffening suspension

摘要

The present invention provides a heat stiffening suspension, comprising: a polymer liquid; and solid particles, wherein said suspension is reversibly activated by temperature to change from a liquid-like state to a solid-like state. Also provided is a method of producing a heat stiffening suspension, wherein said suspension is reversibly activated by temperature to change from a liquid-like state to a solid-like state, comprising the step of contacting a polymer liquid with solid particles at an activating temperature. Further provided is a method of reversibly controlling the physical properties of particle-filled polymers from a fluid-like, viscous state to a solid-like, slightly elastic state in a reversible manner comprising the step of increasing the temperature of a mixture comprising a polymer liquid and solid particles to an activating temperature.
