Integration of ZnO/Au layered structure on silk textiles for realizing a flexible photocatalytic composite material for wearable device applications were conducted in this study. Metallization and deposition of photocatalytic metal oxides on silk textiles were carried out by supercritical CO2 (sc-CO2) promoted electroless plating and cathodic deposition. Due to the flexibility and stretchability, silk was used as the substrate. Gold was selected for its high biocompatibility, electrical conductivity, and ductility. ZnO was deposited on the last layer for performing photocatalytic activity and biocompatibility. Smooth, strong adherence, and uniform coverage of gold layer was successfully electroless plated on the silk with the assistance of sc-CO2. ZnO with wurtzite phase was homogeneously deposited on the gold layer. The optimized ZnO specimen with 0.2 wt.% H2O2 in the ZnO deposition electrolyte showed the highest crystallinity and performed 11.5 times enhancement in the photocurrent density while comparing to that of H2O2-free one.
