Electrospinning can be used in preparation of sub-micron and nanosized fibres. Wide variety of polymers can be used in electrospinning, but natural polymers has proven often to be more challenging compared to synthetic materials. Typical problems concerning natural materials are finding of applicable solvent, low molecular weight, contracted molecular conformation in solution, and charged groups in their structures. In this study electrospinning trials were carried out using three natural polymers. These materials included cellulose, lignin and milk proteins (casein). Electrospinnability of these natural materials were enhanced by chemical modification of polymer, adjusting the electrospinning conditions including different solvents and using auxiliary polymer. Electrospun fibres were obtained with these three polymers.
