ABSTRACT

The present invention relates to a flexible sensing material made from (a) at least one flexible polymeric layer and (b) at least one conductive, curable coating layer containing about 0.01 wt. % to about 5 wt. % of multi-walled carbon nanotubes having a diameter of greater than about 4 nm, about 10 wt. % to about 99 wt. % of an aliphatic urethane acrylate and about 0.1 wt. % to about 15 wt. % of a photoinitiator, wherein the weight percentages are based on the weight of the formulation, wherein the coating layer is curable by exposure to radiation and wherein the cured coating layer has a surface resistivity of about 102Ω/□ to about 1010Ω/□. The inventive sensing material may prove useful for sensing one or more of pressure, temperature and moisture and find use in a wide variety of applications. More... »
