MECHANICAL PERFORMANCE OF PVA/PAN COMPLEXED WITH ALUMINIUM OXIDE (AL2O3) NANOPATICLES FOR SOLID POLYMER ELECTROLYTE
Abstract:
Solid polymer electrolytes (SPEs) have gained significant attention due to their potential applications in various electrochemical devices, including batteries and fuel cells. However, the mechanical properties of SPEs remain a critical challenge that needs to be addressed to enhance their overall performance and stability. In this study, we investigate the mechanical performance of a composite material composed of polyvinyl alcohol (PVA) and polyacrylonitrile (PAN) complexed with aluminium oxide (Al2O3) nanoparticles for solid polymer electrolyte applications.
The PVA/PAN blend offers a combination of good mechanical strength and flexibility, while Al2O3 nanoparticles are known for their excellent mechanical properties and ability to enhance the performance of polymer composites. The incorporation of Al2O3 nanoparticles into the PVA/PAN blend aims to improve the mechanical strength, modulus, and dimensional stability of the resulting solid polymer electrolyte.
The composite films were prepared through a solution casting method, and the effects of varying Al2O3 nanoparticle concentrations on the mechanical properties were systematically investigated. Tensile testing was performed to evaluate the mechanical strength, Young’s modulus, and elongation at break of the composite films. Additionally, the film’s dimensional stability was assessed through thermal analysis and swelling experiments.
Preliminary results showed that the addition of Al2O3 nanoparticles to the PVA/PAN blend led to significant improvements in the mechanical properties of the resulting solid polymer electrolyte. The tensile strength and Young’s modulus increased with increasing Al2O3 nanoparticle concentration, indicating enhanced mechanical integrity. Furthermore, the dimensional stability of the composite films improved, as evidenced by reduced thermal expansion and controlled swelling behavior.
Overall, this study highlights the potential of incorporating Al2O3 nanoparticles into PVA/PAN blends to enhance the mechanical performance of solid polymer electrolytes. These findings contribute to the development of mechanically robust and stable SPEs, which are crucial for the long-term performance and durability of electrochemical devices. Further investigations are warranted to optimize the nanoparticle concentration and explore the electrical conductivity and electrochemical properties of the composite material to fully realize its potential in practical applications.
