英文摘要: A systematic investigation on the allogeneic assembly behaviors of inorganic nanosheets (IONS) including metal oxides and hydroxides (such as manganese dioxide, layered double hydroxides) and graphene/graphene oxide nanosheets, as nanocrystal building blocks, is proposed in this project. Based on the investigation, this project aimed at the performance-oriented fabrication of differently structural nanocomposites, in which the IONS could play the advantageous role in the electrochemistry, luminescence, catalytic performance, etc., fulfilling the complementarity and performance optimization of IONS and graphene, and further giving nanocomposites with novel features. The work will focus on the followings. (1) Through studying on factors of, mainly, the IONS species, the additives including flocculants, dispersing agents, stabilizers, templates, etc., and reduction (methods employed, the reductant species and applying orders), the reaction process and mechanism will be explored for the allogeneic assemblies; (2) by researching the relationship between the composition,structure and the performance of assembled nanocomposites, the basis will be provided for the design of nanocomposites with specific structures and functions, in order to achieve a adjustment of the nanocomposite structures; and (3) the potential appli
