초록

Stearic acid was deposited on surface of 9[MHz], AT-cut quartz crystal microbalance as gas sensing material using Langmuir-Blodgett(LB) technique. We measured gas response between deposited LB films and organic gas for various temperature($0{\sim}80^{\circ}C$). The resonant frequency changed due to absorbance of organic gas such as methanol and butanol gas at room temperature. However, the resonant frequency not responded to methanol gas at temperature above melting point of deposited LB films.
