Claims17
An electrically conductive porous composite comprising:
- a thermally expanded polymer microsphere matrix binding a material composition having electrical conductivity properties to form an electrically conductive porous composite, the expanded polymer microsphere matrix comprising compression and heat-bonded polymer microspheres having been thermally-expanded to fill a fixed volume cavity, the expanded polymer microsphere matrix forming a three-dimensional interconnecting and interpenetrating pore network extending throughout the porous composite and in which the bound material composition having electrical conductivity properties is distributed,
- wherein the electrically conductive porous composite is rigid and comprises a porosity of 30% or more.
