Summary: For the first time, hydrogen bonding complexes between poly(4-vinyl pyridine) (P4VP) and its copolymers were used as a healing concept to build supramolecular materials with self-healability. Through the synthesis of P4VP and its copolymers with stearyl acrylate and stearyl methacrylate, and the formation of complexes with 3,3'-dithiodipropionic acid (DTDP) as a crosslinker, efficient self-healing of complete cuts at room temperature was achieved.

Summary: This article presents how the interplay between H-bonds and dispersive forces can be rebalanced to induce or prevent the generation of kinetic metastable states. The study shows that by favoring dispersive interactions and extending the aromatic content, the cooperative supramolecular polymerization of toluene bis-amide derivatives can be delayed by trapping the metastable inactive state. Proper molecular engineering can create new opportunities for kinetically metastable states in monomers undergoing cooperative supramolecular polymerizations.

Summary: By employing a new V-shaped monomer design, we achieved anticooperatively formed oligomers with superior robustness and high luminescence. The molecular packing modes and (weak) anticooperativity were elucidated by shifting the monomer-oligomer equilibrium to the monomer side in toluene. Steric effects from an antiparallel staircase organization of the dyes restricted the growth at the stage of oligomers, while solvophobic and chain-enwrapping effects led to thermally ultrastable oligomers in methylcyclohexane (MCH). Our findings provide insights into anticooperative effects and restricted growth in self-assembly.

Summary: A new strategy is proposed to improve the distribution of silica in rubber blend without using a silane coupling agent. Silica-filled epoxidized SSBR/ENR nanocomposites have better interfacial interaction and improved dispersion of silica compared to silica-filled SSBR/NR nanocomposites with Si75 as the coupling agent. The epoxy groups effectively adjust the phase selective distribution of silica. The S-ESSBR12/ENR18 nanocomposite shows the best performance, increasing wet-skid resistance by 118%, reinforcing index by 38%, abrasion resistance by 40%, and decreasing rolling resistance by 23%. These ecofriendly nanocomposites have potential application in green tire tread production.

Summary: In this study, a facile two-step approach was used to synthesize self-healing elastomers based on dynamic oxime-carbamate bonds. The formation of hydrogen bonds and dynamic oxime-carbamate bonds was verified through molecular dynamics simulations and experimental characterization. By increasing the hard segment content, the mechanical strength of the elastomer increased while the loss factor decreased. The self-healing behavior of the elastomer was successfully demonstrated at a certain temperature, with dynamic oxime-carbamate bonds playing a more significant role than hydrogen bonds in the mechanism.

Summary: With the rapid development of electronic equipment and communication technology, the demand for polymer composites with high thermal conductivity and mechanical properties has increased significantly. However, its nondegradable polymer matrix will inevitably bring more and more serious environmental pollution. Therefore, it is urgent to develop biodegradable thermally conductive polymer composites. In this work, biodegradable poly(butylene adipate-co-terephthalate) (PBAT) is used as the matrix material, and vacuum-assisted filtration technology is employed to prepare carbon nanotube (CNT) and cellulose nanocrystal (CNC) networks with high thermal conductivity. Then CNT-CNC/PBAT composites with high thermal conductivity and excellent mechanical properties are prepared by the ultrasonic-assisted forced infiltration method. Both experiment and simulation methods are used to systematically investigate the thermally conductive and dissipation performances of the CNT-CNC/PBAT composites. Above all, a simple alcoholysis reaction is applied to realize the separation of the PBAT matrix and functional fillers without destroying the conductive network skeleton, which makes it possible for the recycling of thermally conductive polymer composites.
