Microwave-assisted extraction of acetosolv lignin from sugarcane bagasse and electrospinning of lignin/PEO nanofibres for carbon fibre production

Abstract: Sugarcane bagasse (SB) is an agricultural waste with massive potential as a source of lignin for the production of renewable materials. In this study, acetosolv lignin from SB was extracted efficiently and sustainably via microwave (MW)-assisted extraction within 10 min. Subsequently, acetosolv lignin was subjected to electrospinning into lignin nanofibres (LNFs) for carbon fibre production using an 85/15% w/w lignin/poly (ethylene oxide) blend ratio in a DMF solution after optimisation of suitable electrospinning parameters. The structural characterisation of lignin was accomplished via pyrolysis-gas chromatography with mass spectrometry, heteronuclear single quantum coherence, Fourier-transform infrared spectroscopy, size-exclusion chromatography, and thermogravimetric analysis while the electrospun LNFs were characterised by transmission electron microscope as randomly arranged fibres with diameters ∼15 nm. SB is a readily available and valuable source of lignin for facile MW extraction using acetic acid, while electrospinning was a fast and efficient method for the fabrication of LNFs.
