In 2019,International Journal of Hydrogen Energy included an article by Yao, Jin; Xu, Guoxiao; Zhao, Ziming; Guo, Jing; Li, Shenghai; Cai, Weiwei; Zhang, Suobo. Category: alcohols-buliding-blocks. The article was titled 《An enhanced proton conductivity and reduced methanol permeability composite membrane prepared by sulfonated covalent organic nanosheets/Nafion》. The information in the text is summarized as follows:
Sulfonated covalent organic nanosheets (SCONs) with a functional group (-SO3H) are effective at reducing ion channels length and facilitating proton diffusion, indicating the potential advantage of SCONs in application for proton exchange membranes (PEMs). In this study, Nafion-SCONs composite membranes were prepared by introducing SCONs into a Nafion membrane. The incorporation of SCONs not only improved proton conductivity, but also suppressed methanol permeability. This was due to the even distribution of ion channels, formed by strong electrostatic interaction between the well dispersed SCONs and Nafion polymer mols. Notably, Nafion-SCONs-0.6 was the best choice of composite membranes. It exhibited enhanced performance, such as high conductivity and low methanol permeability. The direct methanol fuel cell (DMFC) with Nafion-SCONs-0.6 membrane also showed higher power d. (118.2 mW cm-2), which was 44% higher than the cell comprised of Nafion membrane (81.9 mW cm-2) in 2 M methanol at 60°. These results enabled to work on building composite membranes with enhanced properties, made from nanomaterials and polymer mols. In the experiment, the researchers used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Category: alcohols-buliding-blocks)
