Determination and monitoring of humidity level is of great importance because
water is one of essential components of the living organisms and materials used by
people. Metal oxides are the most popular materials used as sensing elements for
humidity sensors, due to their excellent thermal and environmental stability, high
mechanical strength, wide range of working temperature, low fabrication cost and
robustness in practical applications. Humidity sensing ability of metal oxide based
ceramic materials can be enhanced by doping with metal cations.
In this work, we present hydrothermal method for preparation of pure and Mgdoped
CuO nanoplatelets and investigate their sensing properties towards humidity.
The proposed method involves autoclaving of copper(II)-acetate solution under
autogenous pressure in alkaline conditions, with different concentrations of Mgdopant
(0, 2.5, 5 and 10 mol%). We have performed thorough structural and optical
investigations of as synthesized mate...rial (TEM, XRD, SAED, UV-VIS-NIR).
Furthermore, we have processed obtained powders into functional thick films using doctor blade technique, and their sensing properties were tested in wide range of
temperatures (25, 50, 75 °C) and relative humidities (40–90%), resulting with strong
response and promising response/recovery times.
