  • Patent number: 8431064
    Abstract: The invention relates to supports consisting of nanoscalar polymer fibers, polymer tubes or hollow fibers for the application and targeted and/or delayed release of ingredients, in particular, agricultural active ingredients. The invention also relates to a method and a device for the production of supports of this type in a charged or empty state. The method and device use electrospinning technology.
