Abstract

<jats:p> The aim of this study was to develop bamboo fiber/polylactic acid/Cloisite 30B nanoclay-based laminated hybrid composites using the film-stacking method. The nanoclay was dispersed in polylactic acid using intermeshing twin-screw extruder and converted into polylactic acid–nanoclay films. Polylactic acid/nanoclay/bamboo fiber hybrid composites were fabricated using temperature-controlled compression molding machine. The dielectric properties were analyzed as a function of frequency (100 Hz–1 MHz) for temperatures in the range from 30°C to 140°C using standard impedance analyzer. Dielectric constant and dissipation factor decreased with increasing frequency for both virgin bamboo–polylactic acid composite and bamboo–polylactic acid nanocomposites. Significant improvement in impact strength of bamboo–polylactic acid nanocomposites was observed as compared to virgin bamboo–polylactic acid composites. The morphology of bamboo–polylactic acid nanocomposites was investigated using scanning electron microscope and transmission electron microscope. </jats:p>
