IMPROVING WOOD POLYMER COMPOSITE PRODUCTION FROM AFRICAN COPAIBA BALSAM WOOD DUST
ABSTRACT
This study focused on the development of wood polymer composites (WPCs) utilizing virgin high-density polyethylene (vHDPE) and wood dust from Daniella oliveri, employing the compression molding technique. The research aimed to enhance the properties of WPCs by subjecting the wood dust to different concentrations of sodium hydroxide (NaOH) for varying durations. The impact of these treatments on the composite’s physical, mechanical, and microstructural attributes was investigated through various analytical methods, including Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM).
To begin with, the study sought to understand the changes in the surface characteristics of both untreated and treated wood polymer samples using FTIR spectroscopy. This analytical technique provides valuable insights into chemical bonds and functional groups present in the materials. The results showed that the alkali treatment of the wood dust had a positive effect on the interaction between the wood dust and the vHDPE matrix.
Furthermore, the research delved into the structural modifications and properties of the WPCs. Scanning electron microscopy was employed to visualize the microstructure of the composites, offering a closer look at how the materials interact at a microscopic level. This analysis revealed the improvements brought about by the alkali treatment, particularly in enhancing the mechanical properties of the WPCs.
The key finding of this study was that the optimal physical, mechanical, and microstructural properties of the WPCs were achieved when wood dusts were treated with a 4wt% concentration of NaOH solution for 150 minutes. This specific treatment duration and concentration appeared to strike a balance, resulting in WPCs with enhanced characteristics. These findings have significant implications for the development of sustainable and high-performance composite materials, particularly in the context of utilizing wood waste in conjunction with thermoplastic polymers like vHDPE.
