Outline of Final Research Achievements

We have succeeded in synthesizing a novel nanocomposite which puts together the conductive graphene and non-conductive periodic mesoporous silica with the mesochannels vertically aligned towards graphene surface and reveals a good electrical conductivity. However, the formation mechanism of the nanocomposite structure has not been elucidated. In this investigation, we attempted to uncover the self-assembling mechanism of surfactants and/or organic silicon precursor on the surface of graphene oxide in the three components mixed solution by changing the synthesis conditions and by direct analysis on the micelle structure on carbon surface. We successfully find synthesis approaches to obtain the nanocomposite in which the silica film thickness was controlled and mesopore size was tuned.
