New Trends in Natural Rubber Nano Composites

摘要

The aim of this study is to investigate the effect of rice husk fibers in absence and in presence of carbon black on the rheological, physical and mechanical properties of rubber composites and vulcanizates. Alkaline treatment was used to remove most of the lignin and hemicellulose compounds from the rice husk fibers followed by drying, milling and sonication leading to get nano- rice husk particles. Different techniques such as TGA, mechanical testing, microstructural analysis (via SEM and TEM), abrasion, hardness and XRD were carried out to characterize compounds and vulcanizates. It has been found that rice husk fibres has a reinforcing effect and improves the mechanical properties of rubber nano composites. Combination of rice husk and HAF carbon black established with very valuable composites as engineering materials.
