-SiO2@ON/glass was coated with poly(methyl methacrylate) (950 PMMA C4, Micro Chem, 2 mL) by spin coating (500 rpm for 5 s, 1,000 rpm for 5 s, 2,000 rpm for 5 s, 1,000 rpm for 5 s, SP-7200GT spin coater, Intec systems). The plate was cut into 4 pieces of 1.5 × 2.5 cm2 area (Refer to Figure S3), and then added to 5% HF solution (100 mL). In the first 1 min, the glass plate was detached from S-SiO2@ON/glass and removed. The S-SiO2@ON was further etched for 2 h. Caution: HF solution is extremely dangerous to be inhaled and touch. Thus, it should be handled with extreme caution and specific gloves in a good hood. Before using the HF solution, please read the MSDS sheets. The PMMA-MONF obtained by etching was washed with water. The PMMA in PMMA-MONF …show more content…
PdCl2 stock solution was prepared by adding water to a mixture of PdCl2 (0.10 g, 0.56 mmol), distilled water (200 mL), and 37% HCl solution (20 mL) to form 1.0 L solution. Both the stock solutions were sonicated to form clear solution. Cu2+ stock solution was prepared by adding water to a mixture of CuSO4·5H2O (5.0 g, 20 mmol), distilled water (700 mL), potassium sodium tartrate tetrahydrate (25 g, 89 mmol), and NaOH (7.0 g, 0.18 mol) to form 1.0 L …show more content…
Ltd). The resistance in bending tests was measured using a Keithley 2400 power supply. For the bending tests, each end side of Cu region on Cu/MONF/PET and Cu/PET was connected to copper plates, and the contact region was fixed with a clip. For the definition of bending angle and bending cycle, refer to Figs. 4b and 4c, respectively. In one bending cycle, Cu/MONF/PET or Cu/PET was bent to 0, 180, 360, and then 180 ° bending angle. After bending cycles, the current was measured by voltage scan in the range from + 1.0 to −1.0 V. The resistance values calculated from the slope were obtained using a Keithley 2400 power
