Raman analysis and morphological studies of lignin-based carbon / sepiolite hybrid materials prepared by
mechanical methods

L
ignin is a kind of biopolymer from woody plants and has complex and heterogeneous aromatic structure with aliphatic moieties.
Industrial lignins including lignosulfonate and kraft lignin are abundant as by-product of pulping process. Because most of lignin
was used for low-cost fuels, high-value utilization of lignin has been studied in many ways. Lignin carbonization is one way of the
high-value utilization of lignin. Due to its low cost, carbon neutrality and relatively high carbon contents among biomass, lignin
receiced attentions as a renewable carbonaceous resource. Sepiolite is a kind of silicate clay minerals. It has fibrous texture and porous
structure with 'channels' and 'tunnels'. In this study, lignin-based carbon / sepiolite hybrid materials are prepared by carbonization of
lignin / sepiolite hybrid materials up to 1000
0
c. Lignin and sepiolite are hybridized by mechanical mixing method. Raman anlaysis
and morphological studies for the hybrid materials were investigated. Lignin-based carbon / sepiolite hybrid materials are expected to
be applied as reinforcement filler or as an absorbent material.
