New discoveries in chemical research and development in 2021. As an important bridge between the micro, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Moon, Sun Ju, once mentioned the application of 273-53-0, Electric Literature of 273-53-0, category is benzoxazole. Now introduce a scientific discovery about this category.
Herein, we fabricated two types of electrospun membrane using: 1) sulfonated poly (arylene ether sulfone), which needs chemical cross-linking to increase its mechanical strength, and 2) thermally rearranged poly (benzoxazole-co-imide), which is mechanically robust while requiring the hydrophilic coating. With a high porosity and low structure parameter of the support layer, two thin film composite (TFC) membranes were fabricated via interfacial polymerization on the support layer using 1,3,5-bezenetricarbonyl trichloride (TMC) and m-phenylene diamine (MPD) monomers. Chlorine modification using NaOCl solution was applied to two TFC membranes (denoted as XBPSH-TFC-Cl and XPBO-TFC-Cl, respectively) to improve water permeability (A) of the polyamide selective layer, while maintaining decent salt rejection values (R). As a result, the highly efficient XPBO-TFC-Cl achieved a peak power density of 26.6 W.m(-2) at 21 bar using 1 M NaClaq and deionized (D.I.) water as draw and feed solutions, respectively. According to the modeling results, XPBO-TFC-Cl was less affected by the adverse phenomena (such as concentration polarization and reverse salt permeation), and showed lower performance reduction for various feed sources compared to XBPSH-TFC-Cl. These results demonstrate the potential of the next generation TFC membranes, which are commonly used for power generation and liquid separation.
