NOVELTY - Preparing conductive stretching open-cell foam composite material involves adding conductive filler and dispersant to water, dispersing uniformly to obtain conductive fillers dispersion. The open cell foam is soaked into the conductive filling dispersion and taking out and drying the material, the material and preserving heat is compressed at high temperature, and cooled to obtain the product. USE - Method for preparing conductive stretching open-cell foam composite material in the field of electromagnetic shielding, and in wave-absorbing material (all claimed). ADVANTAGE - The method is light, stable, and stable in the stretching expansion and stretching process, and has good application prospect in the field of stretchable electromagnetic shielding material and wave-absorbing material.
