Abstract:

Lignin 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 0c. 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.
