ABSTRACT
We fabricated the Langmuir monolayers in a Langmuir-Blodgett trough (MDTcorp., Russia), 240 mm × 100 mm in size and 300 mL in volume, having a compression speed of 1.67 mm/s (100 cm2/min). The spreading solutions of nanocomposites were prepared by dissolving 5 mg of materials in 20 mL of chloroform. The LS films were deposited at air-water interface, maintaining the surface pressure at 25 mN/m [15-18]. We used distilled water as subphase for the deposition in order to obtain films of the materials in the undoped form. 12.2.4 Setup of the Sensing ApparatusIn order to test the sensing properties of the synthesized materials, we set up a homemade glass chamber of 340 mL volume. The homemade chamber (Figs. 12.2 and 12.3) is provided of four input socket for quartzes, a gas valve in, and a gas valve out.
