以六甲氧基甲基三聚氰胺（HMMM）为单体，嵌段共聚物Pluronic F127为模板剂合成了介孔三聚氰胺树脂。在酸性条件下，HMMM缩合成三聚氰胺树脂，复制由嵌段共聚物模板形成的中间相。该模板可以通过溶剂萃取除去，得到具有高达258 m2/g的表面积和7.8 nm的孔径的介孔三聚氰胺树脂。在HMMM/F127重量比为1：1时，观察到有序的介孔三聚氰胺树脂表现出圆柱形孔的2d六边形排列。这些中孔膜的合成简单性允许大规模生产材料，例如以自支撑膜的形式。
Mesoporous melamine resins have been prepared using hexamethoxymethyl melamine (HMMM) as monomer and block-co-polymer Pluronic F127 as template. At acidic conditions, HMMM condenses into melamine resins, replicating the mesophases formed by the block-co-polymer template. The template can be removed by solvent extraction, yielding mesoporous melamine resins with surface areas of up to 258 m(2)/g and pore diameters of 7.8 nm. At a HMMM/F127 weight ratio of 1:1 an ordered mesoporous melamine resin is observed exhibiting a 2d hexagonal arrangement of cylindrical pores. The simplicity of the synthesis of these mesoporous films allows the large Scale production of the materials, for example, in the form of free-standing films.
