Nafion改性多级孔径石墨烯气凝胶制备与性能研究
Nation Modified Graphene Aerogel with Hierarchical Porous Structures
摘要
Abstract
A novel graphene aerogel with pore size less than 1 μtm was synthesized by Sol-Gel method,in which Nation was skillfully introduced as modifiers connecting graphene oxides (GO).Ethylenediamine was used to produce a chemically linked graphene hydrogel during reducing process,which can then be freeze-dried to remove the absorbed water to form graphene aerogel.Nafion in GO solution prohibits the re-stacking of individual graphene sheets during reduction and freeze-drying process.By the above method,the pore size of as-prepared graphene aerogel could be effectively controlled within 1 μm,much less than that of the traditional graphene aerogel (20-100 μm).The new graphene aerogel with unique structure exhibited excellent properties,such as high specific surface area,high porosity,and better electrochemical properties.All data suggest that this graphene aerogel may have promising application prospect in the field of energy.关键词
