“…Compared with polymerization, conductive hydrogels prepared by self-assembly can typically achieve weaker interactions such as p-p stacking, electrostatic interactions, van der Waals forces, hydrogen bonds, and hydrophobic interactions. [126][127][128][129][130][131][132][133][134][135][136][137] Accordingly, better functionalities, mechanical properties, and interfacial affinity can be achieved for self-assembled hydrogels, improving the biocompatibility of synthetic polymers. 38 Moreover, self-assembly plays a vital role in generating multifunctional conductive hydrogels in comparison with the copolymerization and doping strategies because no reactions are involved during this process.…”

“…The presence of this supramolecular binder coating acted to suppress the aggregation of SnO 2 particles, and its ability to self-heal allowed for a robust structure capable of withstanding volume changes after repeated Li insertion cycles. Specifically, the specific capacity of an uncoated SnO 2 sample was 169 mAh/g after 70 cycles, compared to a coated 60 wt % PAH sample, which retained a specific capacity around 500 mAh/g after 70 cycles [75].…”

Traditionally, gels have been defined by their covalently cross-linked polymer networks. Supramolecular gels challenge this framework by relying on non-covalent interactions for self-organization into hierarchical structures. This class of materials offers a variety of novel and exciting potential applications. This review draws together recent advances in supramolecular gels with an emphasis on their proposed uses as optoelectronic, energy, biomedical, and biological materials. Additional special topics reviewed include environmental remediation, participation in synthesis procedures, and other industrial uses. The examples presented here demonstrate unique benefits of supramolecular gels, including tunability, processability, and self-healing capability, enabling a new approach to solve engineering challenges.

“…SnO 2 is a wide band gap n-type MOS material with a band gap width of 3.62 eV at room temperature. It is widely used in various fields such as photocatalysts [16,17], solar cells [18,19], lithium-ion batteries [20,21] and gas sensors [22,23,24]. As a gas sensor, SnO 2 is one of the most widely considered gas sensitive materials due to its better gas sensitivity to various organic and toxic gases.…”

Developing the triethylamine sensor with excellent sensitivity and selectivity is important for detecting the triethylamine concentration change in the environment. In this work, flower-like CeO2-SnO2 composites with different contents of CeO2 were successfully synthesized by the one-step hydrothermal reaction. Some characterization methods were used to research the morphology and structure of the samples. Gas-sensing performance of the CeO2-SnO2 gas sensor was also studied and the results show that the flower-like CeO2-SnO2 composite showed an enhanced gas-sensing property to triethylamine compared to that of pure SnO2. The response value of the 5 wt.% CeO2 content composite based sensor to 200 ppm triethylamine under the optimum working temperature (310 °C) is approximately 3.8 times higher than pure SnO2. In addition, CeO2-SnO2 composite is also significantly more selective for triethylamine than pure SnO2 and has better linearity over a wide range of triethylamine concentrations. The improved gas-sensing mechanism of the composites toward triethylamine was also carefully discussed.
