Design of Melamine Sponge-Based Three-Dimensional Porous Materials toward Applications
2018
Feng, Yi | Yao, Jianfeng
Due to the low density, high porosity, three-dimensional (3D) pore structure, high nitrogen content, and excellent mechanical properties, melamine sponge (MS) has been widely used as the main building block to design and obtain 3D porous materials. Moreover, N-doped porous carbon foam can be formed via a simple carbonization of MS, thus making such carbon foam also an ideal carbon material used either directly or as support to load other materials. So far, many studies have been reported on the modification of MS, carbonized MS, and MS-based composite materials in various applications including oil/water separation, water disinfection, adsorption, fire resistance, electrochemistry, strain/stress sensor, catalysis, and so on. In this Review, structure design of such MS-based materials and modification methods are summarized and discussed, and the obstacles and suggestions for how to design and synthesize such materials with better performance are provided, aiming to promote the wide application of MS in various fields.
