  • Cellulose based functional composites, energy storage devices and manufacturing methods thereof
    Patent number: 10396328
    Abstract: Document discloses new technologies for utilizing cellulose based materials in composites and electrically functionalized structures, such as energy storage devices. The object of the invention is achieved by means of high consistency fibrillated cellulose with at least one functional additive. This high consistency mixture is processed to form the composite structure having a shape and then dried or let to dry.
    Type: Grant

  • Filter structure for filtering a particle-containing gas, method of its manufacture and use of porous paper
    Patent number: 8182580
    Abstract: The invention relates to a novel gas filter structure, a filtering method and a method of producing the filter structure. The structure according to the invention includes a planar, porous isolation material layer (12) having two opposing surfaces. According to the invention both surfaces of the isolation material layer (12) include comprise a porous conductive layer (14, 16) including a porous filtering matrix treated with a conductive material. The conductive material consists of a material different from the support matrix. By use of the conductive layers it is possible to create in the isolation material an electric field that considerably improves the filtering efficiency of the isolation material, especially for small particles.
