a Response behaviors of the developed DC-ThEG to supplied liquid-state water molecules at different temperatures. From (i) to (v), the DC-ThEG exhibited an apparently weakened capacitance response as the temperature increased. At 40 °C, only a slight capacitance change was observed in b the enlarged image of the capacitive response behavior, and at 45 °C, the developed DC-ThEG exhibited no obvious capacitance change except for normal fluctuations in response to liquid-state water molecules, which can be viewed in c the enlarged view of the capacitance response waveform
