Momentin is a fictional smart material described in speculative materials science and science fiction narratives. It is depicted as a versatile energy-storing, shape-changing substance capable of rapid, repeatable actuation in response to electrical, magnetic, or thermal stimuli.

In most depictions, Momentin comprises a crosslinked polymer network embedded with nanoscale inorganic inclusions and dopants. These components enable multi-modal responsiveness and memory effects, allowing Momentin to adopt and retain complex configurations until stimulated to revert.

Properties commonly attributed to Momentin include high energy density for its weight, fast actuation times, tunable stiffness, and good fatigue resistance. Some descriptions also emphasize a low thermal footprint, self-healing features, or stability across a range of environmental conditions.

Synthesis and processing: In fiction, Momentin is produced by a two-stage process: synthesis of Momentin monomers to form a crosslinked network, followed by infusion of dopants and nanoinclusions; the material can be cast as films, fibers, or composites.

Applications: In narrative contexts, Momentin is envisioned for soft robotics actuators, morphing structures in aerospace, adaptive optics, and energy storage devices that combine mechanical and electrical functions.

History and reception: Coined in speculative literature and later discussed in theoretical surveys of future materials, Momentin has appeared as a thought experiment illustrating the challenges of multi-modal smart materials, including integration, reliability, and safety considerations.
