SYNTHESIS AND CHARACTERIZATION OF WASTE WATER SATCHET/ RICE HUSK DUST NANOCOMPOSITE
Abstract
ABSTRACT
This study focuses on the synthesis and characterization of a nanocomposite material made from waste water sachets and rice husk dust, utilizing dual-purpose kerosene (DPK) and automotive gas oil (AGO) as catalysts at varying ratios. The goal is to develop an environmentally friendly composite that combines the properties of waste plastic and agricultural by-products. The waste water sachets, primarily composed of low-density polyethylene (LDPE), were blended with rice husk dust, a lignocellulosic material, to enhance the mechanical and thermal properties of the resulting nanocomposite. The nanocomposites were synthesized through a melt blending process, with DPK and AGO used as catalysts to aid in the dispersion of the rice husk dust within the polymer matrix. Different ratios 50:50, 80:20, 20:80, 100,100 of DPK to AGO respectively were tested to determine the optimal composition for improved performance. Characterization of the nanocomposite was carried out using X-ray Diffraction (XRD) to examine the crystalline structure and phase composition, and Scanning Electron Microscopy (SEM) to analyze the surface morphology and the distribution of rice husk dust in the polymer matrix. A water absorption test was also performed to evaluate the hydrophobicity of the material and its suitability for applications requiring moisture resistance. The results indicate that the DPK and AGO catalysts at 100% DPK ratio significantly influence the dispersion of rice husk dust, improving the mechanical strength and reducing water absorption. The XRD analysis revealed changes in the crystalline structure, while SEM images showed a uniform distribution of the rice husk dust in the polymer matrix. The water absorption test demonstrated enhanced hydrophobicity, making the nanocomposite a promising material for applications in packaging and constructio
