Abstract

In this work we focus on poly(hydroxy ethyl methacrylate)/carbon black composites for the electrical and optical sensing of humidity and alcohols. The sensitivity is a non-monotonous function of carbon load, while processing with and without ultrasonic agitation can lead to substantially different sensitivity levels. In the case of a carbon-loaded film, optical sensing is limited by the transparency of the carbon-loaded film, which, nevertheless, can be manipulated within limits through the choice of casting solvent. Electrical sensitivity of the composites is compared to the optical (thickness-based) and capacitance sensitivities of the carbon-free poly(hydroxy ethyl methacrylate) version. Composites offer a clear sensitivity advantage when their optimized, on the basis or electrical response, version is employed. © 2008 Elsevier B.V. All rights reserved.
