NOVELTY - Preparing porous elastic conductive composite film comprises (1) adding conductive nanomaterials as fillers to water, adding surface modifiers, and stirring and dispersing to obtain conductive filler slurry, (2) adding foaming agent and foam stabilizing agent to the polymer matrix and stirring to form foamed polymer slurry, (3) adding the conductive filler slurry to the foamed polymer slurry, and stirring and mixing to obtain mixed slurry, (4) coating the mixed slurry to the substrate through film coating process, and (5) drying the coated material and peeling from the substrate to obtain porous elastic conductive composite film. USE - The composite film is useful for preparing multiple functional nanomaterials and aqueous polymer porous composite materials, electromagnetic shielding, flexible sensing and flexible heating. ADVANTAGE - The method: can avoid the use of organic solvents and reduce pollution; has simple method, reliability and strong operability; avoids the use of organic solvents; and reduces pollution. The composite film: has porous, excellent electrical conductivity and controllable in thickness; and is compressible and resilient, and large in compression. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for porous elastic conductive composite film prepared by the preparation method and has thickness of 0.04-10 mm and resistivity of 1-42000 Omegaxcm, where the porosity is 16-78%, can be compressed and rebounds, and the compressibility is 12-70%.
