Abstract
An efficient one-step process for forming uniform solid-like layers of ionic liquid (IL) entrapped in colloidal silica network on interdigitated electrodes (IDE) using ultrasonic deposition is described in this communication. The electrical response of such layers deposited on insulating substrates fitted with interdigitated electrodes was measured upon exposure to different gases (H(2), NO(2), CO, and CH(4)) in air demonstrating reversible and sensitive response at 100 degrees C.
