METHOD FOR THE AMBIENT-TEMPERATURE PRODUCTION OF MICRO- AND NANO-FIBRES OF LIGNIN AND OTHER RESINOUS COMPOUNDS

摘要

The invention relates to a method enabling the ambient-temperature spinning of lignins 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.
