“…In the majority of cases, the double modification proceeded in a quantitative manner with low molar mass primary amines and acrylates, under mild conditions, without the presence of any catalyst but in the presence of reactant excess. 74,78,89,105 As evidenced by MALDI ToF analyses, this double modification strategy was also successfully applied to thiolactone end-terminated polymers (PEO and polycaprolactone) and to the synthesis of midchain functionalized block copolymers via polymer-polymer conjugation (Figure 9). 98 When the double modification is carried out in the presence of both primary amine and acrylates compounds, aminolysis is the rate-determining step.…”

“…This scope facilitates the detection of gases, metal ions, and molecules. 762 Zhao et al synthesized isoporous honeycomb membranes, HIPMs, based on the homopolymer poly(1-vinyl-3-cyanomethyl-imidazolium bis(trifluoromethane sulfonyl)imide), PVCMImTf 2 N, electrostatically cross-linked with Cpillar [5]arene, by aqueous ammonia in a solution-casting process. 259 When copper cations were adsorbed into such HIPMs (coatings), linear increases in refractive index caused red shifts probed by thin-core fiber mode interferometry (TCFMI).…”

The breadth and importance of polymerized ionic liquids (PILs) are steadily expanding, and this review updates advances and trends in syntheses, properties, and applications over the past five to six years. We begin with an historical overview of the genesis and growth of the PIL field as a subset of materials science. The genesis of ionic liquids (ILs) over nano to meso lengthscales exhibiting 0D, 1D, 2D, and 3D topologies defines colloidal ionic liquids, CILs, which compose a subclass of PILs and provide a synthetic bridge between IL monomers (ILMs) and micro to macroscale PIL materials. The second focus of this review addresses design and syntheses of ILMs and their polymerization reactions to yield PILs and PIL-based materials. A burgeoning diversity of ILMs reflects increasing use of nonimidazolium nuclei and an expanding use of step-growth chemistries in synthesizing PIL materials. Radical chain polymerization remains a primary method of making PILs and reflects an increasing use of controlled polymerization methods.Step-growth chemistries used in creating some CILs utilize extensive cross-linking. This cross-linking is enabled by incorporating reactive functionalities in CILs and PILs, and some of these CILs and PILs may be viewed as exotic cross-linking agents. The third part of this update focuses upon some advances in key properties, including molecular weight, thermal properties, rheology, ion transport, self-healing, and stimuli-responsiveness. Glass transitions, critical solution temperatures, and liquidity are key thermal properties that tie to PIL rheology and viscoelasticity. These properties in turn modulate mechanical properties and ion transport, which are foundational in increasing applications of PILs. Cross-linking in gelation and ionogels and reversible step-growth chemistries are essential for self-healing PILs. Stimuli-responsiveness distinguishes PILs from many other classes of polymers, and it emphasizes the importance of segmentally controlling and tuning solvation in CILs and PILs. The fourth part of this review addresses development of applications, and the diverse scope of such applications supports the increasing importance of PILs in materials science. Adhesion applications are supported by ionogel properties, especially crosslinking and solvation tunable interactions with adjacent phases. Antimicrobial and antifouling applications are consequences of the cationic nature of PILs. Similarly, emulsion and dispersion applications rely on tunable solvation of functional groups and on how such groups interact with continuous phases and substrates. Catalysis is another significant application, and this is an historical tie between ILs and PILs. This component also provides a connection to diverse and porous carbon phases templated by PILs that are catalysts or serve as supports for catalysts. Devices, including sensors and actuators, also rely on solvation tuning and stimuliresponsiveness that include photo and electrochemical stimuli. We conclude our view of applications with 3D printi...

The low‐temperature response and the notion of crystallization kinetics are critical for developing elastomeric composite fibers, thus the crystallization and mechanical properties are essential for the application of composites of polybutadiene at low temperatures. Despite the high amount of fiber joining and entanglement due to polymers' low glass transition, a defect‐free micro‐scale electrospun carbon nanotube (CNT)‐containing poly(ethylene oxide) (PEO) and polybutadiene (PBu) composite elastomeric fibers with uniform fiber diameter and distribution are successfully fabricated. Thermomechanical behavior analyzed via frequency‐dependent dynamic mechanical analysis under cryogenic conditions shows a remarkable increase in decomposition temperatures (Tend) and storage and loss modulus at cryogenic temperatures, particularly when small amounts of CNTs are present. Dynamic mechanical treatment from 120 K to elevated temperatures yields a pronounced logarithmic increase in Tend by an increase of PEO content (from BEC1 to BEC4) compared to the treatment from 300 K. Through X‐ray diffraction, large shifts toward larger 2θ and formation of new crystals are observed, particularly for the BEC4 sample with high PEO content. Nanoparticles after cryo‐treatment linked with crystallinity are registered by ultra‐high resolution scanning electron microscopy. Improving the thermal and mechanical properties is critical in developing high‐performance composite fibers for cryogenic engineering applications, especially for future research to facilitate them in aerospace and low‐temperature medical and surgical treatments.
