In general, the mechanical properties of graphene/GO membranes depend significantly on their chemical functionalization and crosslinking to other nanomaterials. GO exposes numerous carboxy and hydroxyl groups and, hence, it is expected to show good affinity to the surface of TNCs. Further, TNCs are known to reduce GO to reduced graphene oxide (rGO) in solution as well as in films under ultraviolet irradiation based on their photocatalytic activity. Here, we used a stamping method to fabricate freestanding membranes composed of titania nanorods (TNRs), GO, and SF (TNR/GO/SF). The incorporation of TNRs into the composite membranes enabled the facile and well-controlled photocatalytic reduction of GO via exposure to deep-ultraviolet (DUV) irradiation. The effect of the DUV treatment on the mechanical properties was probed via atomic force microscopy (AFM) bulge tests. Furthermore, the formation of rGO during DUV treatment induced electrical conductivity and enabled the electrostatic actuation of the resulting freestanding TNR/(rGO/GO)/SF membranes.
