含三嗪环结构耐酸纳滤膜的制备及性能研究进展OA

The triazine ring exhibits excellent mechanical properties,thermal stability,and acid stability.Acid-resistant nanofiltration membranes prepared via interfacial polymerization of triazine ring-containing monomers can be employed for treating acidic wastewater.To address issues such as the relatively low reactivity of triazine ring-containing monomers and the trade-off between permeability and rejection rate in acid-resistant nanofiltration membranes incorporating triazine ring structures,researchers have employed multiple approaches to enhance the separation performance of composite membranes.The research progress on the preparation of acid-resistant nanofiltration membranes by introducing triazine ring structures through interfacial polymerization in recent years was reviewed.Advances in three aspects were summarized:interfacial polymerization based on organic phase monomers of cyanuric chloride,interfacial polymerization based on aqueous phase monomers containing triazine ring structures,and process improvements for interfacial polymerization of triazine ring-containing monomers.Moreover,the existing problems and prospects for future development in this fieldwere expected.
