## Description

- description: "Stimuli-responsive polymers with complicated but controllable shape-morphing
    behaviors are\r\ncritically desirable in several engineering fields. Among the
    various shape-morphing materials,\r\ncross-linked polymers with exchangeable bonds
    in dynamic network topology can undergo\r\non-demand geometric change via solid-state
    plasticity while maintaining the advantageous\r\nproperties of cross-linked polymers.
    However, these dynamic polymers are susceptible to creep\r\ndeformation that results
    in their dimensional instability, a highly undesirable drawback that\r\nlimits
    their service longevity and applications. Inspired by the natural ice strategy,
    which\r\nrealizes creep reduction using crystal structure transformation, we evaluate
    a dynamic crosslinked polymer with tunable creep behavior through topological
    alternation. This alternation\r\nmechanism uses the thermally triggered disulfide–ene
    reaction to convert the network topology – from dynamic to static – in a polymerized
    bulk material. Thus, such a dynamic polymer\r\ncan exhibit topological rearrangement
    for thermal plasticity at 130°C to resemble typical\r\ndynamic cross-linked polymers.
    Following the topological alternation at 180°C, the formation\r\nof a static topology
    reduces creep deformation by more than 85% in the same polymer. Owing\r\nto temperature-dependent
    selectivity, our cross-linked polymer exhibits a shape-morphing\r\nability while
    enhancing its creep resistance for dimensional stability and service longevity
    after\r\nsequentially topological alternation. Our design enriches the design
    of dynamic covalent\r\npolymers, which potentially expands their utility in fabricating
    geometrically sophisticated\r\nmultifunctional devices."
