    An aqueous iminoboronate multi-component reaction is designed to fabricate a triple-sensitive polymer whose nano-aggregates can be dissociated with stimuli of UV light, acid, and H2O2, respectively.

    Small molecules automatically self-assemble into liquid-crystalline membranes to form supramolecular hydrogels with an interlayer spacing of 40 nm. The membrane domains act as physical crosslinks in these hydrogels via the cooperative hydrogen-bonding between membranes and linear polymers. These hydrogels show unique properties, such as temperature-dependent mechanical performance/optical transmittance, which have potential applications in biological membranes, drug release, and optical filters.

  3. Bioinspired Design of a Robust Elastomer with Adaptive Recovery via Triazolinedione Click Chemistry

    Inspired by “sacrificial bond”, the clusters based on hydrogen bonds, which form a separated microphase, are engineered into a pre-crosslinked diene rubber via triazolinedione click chemistry. The clusters serve as sacrificial bonds during stretching efficiently dissipate energy, improving the overall mechanical properties of the rubber. Simultaneously, their hierarchical stability endows the rubber with promising triple-shape memory behavior.

  4. Synthesis of Hydroxy-Functionalized Cyclic Olefin Copolymer and Its Block Copolymers with Semicrystalline Polyolefin Segments

    Xiangyang Song, Lijun Yu, Takeshi Shiono, Tariqul Hasan and Zhengguo Cai

    Living/controlled copolymerization of norbornene and polar monomer has been achieved with remarkably high activity by using the fluorenylamide–ligated titanium complex to produce hydroxy-functionalized cyclic olefin copolymer and its block copolymers with semicrystalline polyolefin sequences.

  5. Omnidirectional Shape Memory Effect via Lyophilization of PEG Hydrogels

    Di Chen, Xuhui Xia, Tuck W. Wong, Hao Bai, Marc Behl, Qian Zhao, Andreas Lendlein and Tao Xie

    A novel shape memory programming method is presented utilizing lyophilization of a crosslinked hydrogel with a thermal transition in its dry state. The method allows significant omnidirectional shrinkage upon heating triggered recovery from a porous dried gel to a compact structure, which can hardly be achieved by other programming methods.
