Electrochemically assisted deposition of sol–gel films on graphene nanosheets
Due to physical collisions and electron transfer between the working electrode and conductive nano-materials, electrochemical reactions can occur on the surface of both.

| description | Due to physical collisions and electron transfer between the working electrode and conductive nano-materials, electrochemical reactions can occur on the surface of both. Here, we explore the use of an electrochemically assisted sol–gel deposition technique (EAT) to modify the surface of nanomaterials. Taking graphene as an example, the fabricated free-standing graphene–silica nanosheet composite exhibits a sandwich structure, with mesoporous silica films covering both sides of the graphene. The thickness of the nanocomposites can be tuned (up to ∼50 nm) by controlling the potential and duration of the deposition, and the concentration of the sol–gel precursor. The approach ensures, uniquely, that the silica films are securely attached to the graphene substrate. This indirect deposition technique could also be used for the surface modification of other nanomaterials. Keywords: Electrodeposition, Collision, Silica, Graphene, Sol–gel |
