Effect of ionic liquids/water pre-treatment of Luffa fibres on the structural properties

摘要

Recently, the use of lignocellulosic fibres to reinforcing composite has received an increased attention. However, lack of good interfacial adhesion makes important the treatment of raw materials. In this study, the raw material Luffa fibres were treated by ionic liquids/water mixture and this treatment proved to be useful by elimination of gummy and waxy substances. The effect of the treatments on the structure of fibres was showed using SEM and XRD (X-Ray Diffraction) analysis. The SEM results revealed that the treatment resulted in a removal of lignin, pectin and hemicellulose substances, and change the characteristics of the surface topography. The XRD analysis shows the increase of crystallinity index.
