Based Aerogel Composites as Conductimetric Sensors

Carbon-Based Aerogel Composites as Conductimetric Sensors 

Carbon aerogels cannot readily be used for optical sensors, because they absorb light strongly across the visible region (they appear black) (Chap. 36). But many organic species adsorb onto carbon surfaces, so measurements based on changes in an electrical response are possible if the material is conductive. 

Bryning et al. [25] have reported the preparation of carbon nanotube aerogels, reinforced with polyvinyl alcohol. These materials conduct and have structural integrity, and show promise for sensing applications.
