要旨

Temperature monitoring with high-pressure resistance, precision, and sensitivity is crucial for temperature measurement in complex environments. Traditional temperature sensors are limited by the sensitivities and cannot meet the requirements for temperature sensing under high-pressure conditions. Here, we propose a straightforward method to modulate supramolecular interactions within ionic liquids by doping them with metal salts, thus achieving enhanced temperature sensitivity. Iron-ion doping in 1-butyl-3-methylimidazolium dicyanamide ([BMIm][N(CN)2]) led to exceptional sensitivity (>20%/°C) and detection of minute temperature differences (0.01 °C). Besides, polyurethane swollen by ionic liquids successfully detected temperature changes under a high pressure of 2000 N. Importantly, the approach allows studying structure–property relationships and demonstrates the potential of ionic liquids in high-pressure temperature monitoring, catering to the temperature monitoring needs in various complex environments.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
