The nanobiocomposites synthesis from biomass and its characterization

Abstract

This study was conducted to evaluate the suitability of using hexagonal boronnitride (hBN) as reinforcement in natural fibres obtained from hazelnut shell (F)and poppy straw (H). Raw materials were treated with alkali to enrich the cellulosecontent by removing lignin and hemicellulose. The nanobiocomposite synthesiswas performed with 4% and 8% of hBN. Lignin, cellulose and hemicellulosescontents of biomass were determined. Cellulose content was almost increased3-fold and 2-fold after pretreatment of hazelnut shell (FCell) and poppy straw(HCell), respectively. Strong bands at 812 and 1380cm-1 corresponding tohBN were observed in the FTIR. SEM images showed that hBN is retainedon the pretreated natural fibres. Adsorbed hBN on the structure was highestin the microcrystalline cellulose (Cell) (91.5%), followed by FCell (80.5%) andHCell (50.5%). Nanobiocomposites containing lignocellulose and hBN may berecommended for use in polymer matrix structures where thermal properties needto be altered.
