Abstract

The objective of this study is to prepare Beechwood xylanFilms, reinforce it with varying amounts of nanoeiskers from a Philippine-grown bamboo species (Bambusa blumeana J. A. & J. H. Schultes) nanowhiskers, and to determine the effect of varying bamboo nanowhiskers concentrations on the grammage, bulk density thickness rupture strength water vapor transmission rate and smoothness of the film surface. The morphology of the nanocomposite films was determined via Atomic Force Microscopy. Varying the concentration of the nanowhiskers does not have a significant effect on the grammage, bulk density, and thickness of the films. However, the rapture strength of the films increased significantly with increasing nanowhiskers content. The highest rupture strength (23, 12.23 Pa) was obtained in the film with 10% nanowhiskers. Furthermore,the water vapor transmission rate of the films decreased significantly with increasing nanowhiskers content, although the lowest recorded value of 0.9594g-mil/m day was at 5% nanowhiskers reinforcement. Finally, the smoothness of the films decreased with increasing nanowhiskers concentration.
