A well-ordered hierarchically micromesoporous carbon has been successfully fabricated in a reverse microemulsion system via a heated evaporation-induced self-assembly (HISA) method. An additional heat accelerates the rate of the solvent evaporation for accomplishing the self-assembly process of the surfactant. Interestingly, it only takes about 7 min for the preparation of polymer by using this facile HISA. The tedious prepolymerization process between phenol and resorcinol can be saved by directly mixing them together in the system, and the subsequent thermal consolidation process at 100 °C for about 24 h in the usual method can also be eliminated. Meanwhile, evaporation-induced self-assembly (EISA) and hydrothermal (HT) approaches have also been employed to prepare the porous carbon in F127/MMA reverse microemulsion. Hierarchically porous carbon materials prepared by using reverse microemulsion as the electrode of supercapacitors exhibit an excellent performance in electrochemical application. Hierarchically porous organosilica materials and Si/C nanocomposites have also been prepared in the reverse microemulsion by utilizing HISA, which indicates the universality of this versatile approach. This general approach can provide a facile and sustainable route to construct the architecture of hierarchically porous materials for various applications.

反向微乳体系制备多孔材料的通用方法

通过加热蒸发诱导自组装（HISA）方法，已在反向微乳液系统中成功制备了有序的分层微孔碳。额外的热量加速了溶剂的蒸发速度，以完成表面活性剂的自组装过程。有趣的是，使用这种简便的HISA只需约7分钟即可制备聚合物。通过将苯酚和间苯二酚在系统中直接混合在一起，可以避免繁琐的预聚合过程，并且可以省去随后在常规方法中于100°C进行约24小时的热固结过程。同时，还采用了蒸发诱导自组装（EISA）和水热（HT）的方法来制备F127 / MMA反向微乳液中的多孔碳。通过使用反向微乳液作为超级电容器的电极制备的多级多孔碳材料在电化学应用中表现出优异的性能。还通过利用HISA在逆向微乳中制备了多孔的有机硅材料和Si / C纳米复合材料，这表明这种通用方法的普遍性。这种通用方法可以为构建用于各种应用的分层多孔材料的体系结构提供一种简便且可持续的途径。这表明了这种通用方法的普遍性。这种通用方法可以为构建用于各种应用的分层多孔材料的体系结构提供一种简便且可持续的途径。这表明了这种通用方法的普遍性。这种通用方法可以为构建用于各种应用的分层多孔材料的体系结构提供一种简便且可持续的途径。
