Özet

In this work, N-cyclohexylmethacrylamide (NCMA) Langmuir-Blodgett (LB) thin films are characterized by Surface Plasmon Resonance (SPR) and Quartz Crystal Microbalance (QCM). The fitted SPR data is utilized to be calculating the film thickness of this material and is found to be as 0.76±0.08 nm for single layer. The sensing behaviors of LB films are investigated with respect to volatile organic compounds (VOCs) at room temperature. The sensing responses of the films against to VOCs are measured by the QCM method. It is found that the NCMA film exhibits good response, reversibility, stability, fast response and recovery characteristic to VOCs.
