  • Biodegradable absorbents and methods of preparation
    Patent number: 8183427
    Abstract: A biodegradable microfiber absorbent comprises a substantially homogeneous mixture of at least one hydrophilic polymer and at least one biodegradable polymer. The absorbent can be prepared by an electro hydrodynamic spinning of a substantially homogeneous polymer mixture. Medical dressings for burns and wounds, cavity dressings, drug delivery patches, face masks, implants, drug carriers that comprises at least one microfiber electrospun from a polymer mixture are provided. The dressings can have variable water vapor penetration characteristics and variable biodegradation times.
    Type: Grant
    Filed: December 7, 2010
    Date of Patent: May 22, 2012
    Inventors: Bronislava G. Belenkaya, Valentina I. Sakharova, Vyacheslav N. Polevov, Claudia Polevov, legal representative
