“…Namely, incorporating nanofillers into a polymer matrix can enhance damping performance. [270][271][272] However, the daunting agglomeration issue of nanofillers hinders the further improvement of damping property. [273][274][275][276][277] Toward this end, our group has prepared various nanoparticle ionic materials (NIMs) as novel nanofiller phases to enhance the damping property of polymer-based composites, such as including carbon nanotubes (CNTs)-based NIMs, graphene oxide (GO) based NIMs, (Reproduced with permission.…”

Porous liquids (PLs), an emerging type of flowing liquid materials that combine the merits of porous solids and flowing liquids, have garnered immense attention since the concept of PLs was proposed in 2007. Meanwhile, PLs have witnessed growing success in versatile synthesis strategies and emerging applications, especially since 2017. Given the lack of a timely comprehensive review, developing a prompt summary with a comprehensive understanding is undoubtedly urgent. Thus, this critical review offers a comprehensive summary of the progress in fundamental chemistry, developmental history, synthetic strategies, and emerging applications of PLs. First, the fundamental chemistry and developmental history are reviewed. Then, the synthesis strategies of PLs are highlighted. Additionally, crosscutting studies of pure theoretical simulations are reviewed. Meanwhile, the daunting characterization issues of PLs are analyzed. Next, the state-of-the-art of PLs applications is reviewed in detail. In the end, perspectives regarding the remaining challenges and future directions for PLs are presented. It is speculated that this critical comprehensive review of PLs could inspire scientific communities who focus on the taskspecific materials for various applications, such as gas sorption, membrane separation, catalytic conversion, chiral separation, thermal management and electrolyte, and so on.

“…Viscoelastic damping materials has long been recognized as one of the effective ones for reducing vibration and noise because of their unique viscosity and elasticity. And it has been widely applied in the military fields such as aerospace and naval vessels and civil vibration and noise reduction fields such as transportation, bridges, buildings, precision instruments, etc 3–6 . However, the glass transition temperature range (around 40°C) of pure rubber elastomers are generally narrow and most of their glass transition temperature are below room temperature, 7 which is difficult to meet the actual requirements.…”

The design and synthesis of high‐performance polyurethane with excellent damping performance and superior mechanical property is a challenge owing to conflicting attributes of damping and mechanical performance. Herein, we innovatively introduced dynamic aromatic disulfide bonds and suitable disulfide catalysts into the system and synthesized a polyurethane elastomer with both admirable damping performance (wide damping temperature range [tan δ ≥ 0.3] of 148°C) and excellent mechanical properties (16.8 MPa, 960%). In our design, (i) dynamic aromatic disulfide exchange reaction above room temperature is able to enhance energy dissipation and segmental mobility, thus promoting the damping performance of polyurethane; (ii) the introduced catalyst can further promote dynamic exchange of disulfide bonds above room temperature, making the chains easier to move and leading to excellent damping property. Moreover, by adjusting the chain extension coefficient, the molecular structure of the chain extender, it's easy to design the microphase separation and rigid structure of the elastomer and the system is endowed with improved mechanical strength. Owing to its outstanding properties, the elastomer has great potential to be used for practical application.

“…Thus, they usually exist drawbacks of poor interfacial compatibility and dispersion in the resin, resulting in a discounted toughening effect. In recent years, amphiphilic block copolymers have aroused great interest for toughening epoxy thermosets because they can self‐assemble into well‐dispersed nanoscale spherical, vesicles, and wormlike micelles in the epoxy matrix during curing, and the so‐called reaction‐induced phase separation occurs accordingly . Benefited from “epoxy‐philic” blocks, the self‐assembled micelles of amphiphilic block copolymers usually exhibit good miscibility with epoxy resin.…”

The partial aminolysis of poly(styrene-alt-maleic anhydride) (SMA) with 3-aminopropyltriethoxysilane (APTES) was carried out followed by in situ hydrolytic condensation of the silane, for inducing the self-assembly of SMA to prepare an organic-inorganic hybrid colloidal particle (SMA-APTES). The obtained SMA-APTES particles were then employed as a toughener for modifying diglycidylether of bisphenol A/anhydride thermoset. When the additive amount of the modifier was 5 wt %, an optimal overall performance was achieved. Compared to neat epoxy thermoset, the tensile strength, elongation-at-break, impact strength, and fracture toughness were increased by 67.6, 159, 170.5, and 230.9%, respectively. Although SMA-APTES particles inherently had low glass-transition temperature (T g ) and thermal stability, the T g and thermal stability of above case were comparable to that of neat epoxy resin. It was contributed by the remarkable increase in the crosslink density offsetting this shortage. Therefore, SMA-APTES particle was proved to be an effective and promising modifier for epoxy thermoset.
