Formation of Silica/Graphene Oxide Hybrid Nano Films by Layer-by-Layer Self-Assembly and Biomimetic Silicification

Silica/graphene oxide hybrid thin films were formed by layer-by-layer self-assembly and biomimetic silicification, and the thickness and structure of hybrid thin films were finely controlled at the nanometer scale, by tuning number of the layer-by-layer process. The physical properties of thin films were characterized by infrared spectroscopy, atomic force microscopy, and scanning electron microscopy. In addition, silica/graphene oxide hybrid thin films were successfully utilized for cell culture platforms.
