Abstract It is essential and of great significance to impart high mechanical performance, environmental stability, sensitivity emerging flexible temperature sensors. In this work, polymerizable deep eutectic solvents are designed prepared by simply mixing N‐cyanomethyl acrylamide (NCMA) containing an amide group a cyano in the same side chain with lithium bis(trifluoromethane) sulfonimide (LiTFSI), obtain supramolecular polyNCMA/LiTFSI gels after polymerization. These exhibit excellent performance (tensile strength 12.9 MPa fracture energy 45.3 kJ m −2 ), strong adhesion force, high‐temperature responsiveness, self‐healing ability, shape memory behavior due reversible reconstruction ability hydrogen bonds cyano‐cyano dipole‐dipole interactions gel network. addition, also demonstrate good stability 3D printability. To verify its application potential as sensor, gel‐based wireless monitor developed displays outstanding thermal (8.4%/K) over wide detection range. The preliminary result suggests promising PNCMA pressure sensor.

Interfacial Polymerization at the Alkane/Ionic Liquid Interface

Angewandte Chemie International Edition, Journal Year: 2021, Volume and Issue: 60(26), P. 14636 - 14643

Published: May 19, 2021

Abstract Polymerization at the liquid–liquid interface has attracted much attention for synthesizing ultrathin polymer films molecular sieving. However, it remains a major challenge to conduct this process outside alkane–water since not only suffers water‐caused side reactions but also is limited water‐soluble monomers. Here, we report interfacial polymerization alkane/ionic liquid (IP@AILI) where ionic acts as universal solvent diversified amines synthesize task‐specific polyamide nanofilms. We propose that IP@AILI occurs when acyl chloride diffuses from alkane into instead of being triggered by diffusion in conventional system, which demonstrated thermodynamic partitioning and kinetic monitoring. The prepared nanofilms with precisely adjustable pore sizes display unprecedented permeability selectivity various separation processes.

Advances in Ionic Thermoelectrics: From Materials to Devices

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(9)

Published: Jan. 20, 2023

Abstract As an extended member of the thermoelectric family, ionic thermoelectrics (i‐TEs) exhibit exceptional Seebeck coefficients and applicable power factors, as a result have triggered intensive interest promising energy conversion technique to harvest exploit low‐grade waste heat (<130 °C). The last decade has witnessed great progress in i‐TE materials devices; however, there are ongoing disputes about inherent fundamentals working mechanisms i‐TEs, comprehensive overview this field is required urgently. In review, prominent effects, which set ground for materials, or more precisely, thermo‐electrochemical systems, first elaborated. Then, TE performance, capacitance capability, mechanical properties such system‐based followed by critical discussion on how manipulate these factors toward higher figure‐of‐merit, examined. After that, prevalent molding methods assembling into devices summarized. To conclude, several evaluation criteria proposed quantitatively illustrate promise practical applications. It therefore clarified if recent trend developing i‐TEs can continue, recycling landscape will be significantly altered.

Ionic liquids (ILs) hold great promise in the fields of green chemistry, environmental science, and sustainable technology due to their unique properties, such as a tailorable structure, various types available, environmentally friendly features. On basis multiscale simulations experimental characterizations, two features ILs are follows: (1) strong coupling interactions between electrostatic forces hydrogen bonds, namely Z-bond, (2) semiordered structure properties ultrathin films, specifically regarding quasi-liquid. In accordance with aforementioned theoretical findings, many cutting-edge applications have been proposed: for example, CO2 capture conversion, biomass conversion utilization, energy storage materials. Although substantial progress has made recently field ILs, considerable challenges remain understanding nature devising especially terms e.g. situ/real-time observation highly precise Z-bond this Perspective, we review recent developments IL research community provide insights into function which will facilitate future applications.
