  • Publication number: 20190032247
    Abstract: The invention relates to a continuous, scalable and parallelizable method for preparing strong and stiff fibres (filaments) or films. The fibre or film is prepared by utilizing hydrodynamically induced alignment of the constituents of a dispersion in combination with surface-charge controlled gel transition to produce fibres with a high degree of alignment of the constituents (polymer(s), fibrils etc.). The invention also relates to the fibres or films so formed.
    Type: Application

  • Patent number: 10099192
    Abstract: The present invention relates to a method for the preparation of polymer shells, preferably composed of cellulose or hemicellulose, comprising the steps of dissolving the polymer component in a first solvent, preferably an organic solvent and precipitating the polymer component by contacting the first solution with a second solvent, which second solvent has a polar character, and in which second solvent the polymer component is essentially insoluble, thereby obtaining polymer shells. Moreover, the invention refers to the polymer shells as such, having permeable and responsive properties, as well as various applications comprising such polymer shells within the fields of drug delivery, separation techniques, and inter alia filling material.
