초록

영어
In this study, a suspension of lignocellulose nanofibril (LCNF) and poly (vinyl alcohol) (PVA) was used to fabricate PVA/LCNF electrospun nanofibers through electrospinning. LCNF was prepared by alkaline-peroxide (AP) pretreatment to control lignin and hemicellulose contents, and was subjected to be fibrillated by sequential treatment with wet disk-milling (WDM) and high pressure homogenizer (HPH). The morphological characteristics of WDM and HPH treated LCNFs were investigated by field emission scanning electron microscopy (FE-SEM) and the average diameter and the filtration time were compared. The viscosity of the suspension of PVA and LCNFs treated with WDM and HPH was measured. Then, PVA/LCNF electrospun nanofiber was obtained by electrospinning. The obtained PVA/LCNF electrospun nanofiber was observed by FE-SEM and the average diameter was measured. The resulting diameter of LCNF decreased with reduction of lignin and hemicellulose content. In suspension containing PVA and untreated LCNF, the viscosity of the suspension increased and the diameter of the electrospun nanofiber increased with increasing suspension concentration or LCNF addition. The reduction of lignin and hemicellulose also increased the viscosity of the PVA/LCNF suspension and the diameter of the electrospun nanofiber.
