  • METHOD FOR THE AMBIENT-TEMPERATURE PRODUCTION OF MICRO-AND NANO-FIBERS OF LIGNIN AND OTHER RESINOUS COMPOUNDS
    Publication number: 20100311943
    Abstract: The invention relates to a method enabling the ambient-temperature spinning of ligning originating from Alcell- and Organosolv-type extraction processes. The invention also relates to a method and device for the ambient-temperature production of lignin fibres of micro- and nanometric diameter, by means of electrospinning and co-electrospinning. The resulting fibres can be single strand (electrospinning) and hollow or coaxial (co-electrospinning) fibres. The lignin fibres are transformed into carbon nanofibres after a suitable heat treatment.

  • Procedure to generate nanotubes and compound nanofibres from coaxial jets
    Patent number: 7794634
    Abstract: The invention relates to a method of producing nanotubes from coaxial jets of immiscible liquids or poorly-miscible liquids. The purpose of the invention is to produce hollow fibers (nanotubes) or composite fibers having diameters ranging from a few micras to tens of nanometers and comprising walls, in the case of nanotubes, with a thickness ranging from hundreds of nanometers to a few nanometers. The inventive nanotube-formation method involves the generation of coaxial nanojets of two liquids using electrohydrodynamic technology.
