The present disclosure relates to a composition for sensor films used for detecting chemical analytes within sensors, such as polymer-absorption chemiresistors (i. e. , conductometric sensors). The present disclosure provides robust sensor film compositions that have low resistance, high conductivity, and greater temperature stability and sensitivity to chemical analytes, as well as methods of making these sensor films. Sensor film compositions according to the present disclosure include a matrix having a polymer resin comprising siloxane and a plurality of conductive particles including at least two distinct species.

Compositions for sensor films used for detecting chemical analytes within sensors, such as polymer-absorption chemiresistors (i. e. , conductometric sensors) are provided. Robust sensor film compositions that have low resistance, high conductivity, and greater temperature stability and sensitivity to chemical analytes are provided, as well as methods of making these sensor films. Such sensor film compositions include a matrix having a polymer resin and a plurality of conductive particles comprising an axial-geometry conductive particle. Exemplary axial-geometry conductive particles comprise graphene, such as a carbon nanotube. Blends of conductive particles are also contemplated, including blends of axial-geometry conductive particles, such as carbon nanotubes, and carbon black.

The invention provides polymeric PTC compositions and electrical PTC devices with high voltage capability and high switch temperatures. The polymeric PTC composition specifically includes perhydrotriphenylene as an organic polymer component which, when blended with a crystalline or semi-crystalline organic polymer component such as polyethylene, gives rise to a composition having a melting point, Tm of up to about 181Â C.
