Description

Application

• Electromagnetic Interference Shielding: Paraffin wax is used as a matrix to embed composites such as NiZn ferrite, carbonyl iron, and carbon black. These composites are prepared to evaluate their electromagnetic interference (EMI) shielding properties. Studies have shown that paraffin wax composites provide effective EMI shielding, which is crucial for protecting electronic devices from electromagnetic interference. This application is significant for developing advanced materials for electronic and communication industries (Journal of Chemistry: Education Research and Practice, 2022).


• Material Science and Surface Protection: Paraffin wax is utilized in the preparation of nanoemulsions to protect wood surfaces. For instance, paraffin wax nanoemulsions containing cerium oxide nanoparticles have been developed to enhance the surface protection of wood against UV radiation and weathering. This application is crucial for extending the lifespan of wood materials used in construction and furniture, ensuring their durability and resistance to environmental factors (Materials Chemistry and Physics, 2023).


• Phase Change Materials (PCMs) for Thermal Energy Storage: Paraffin wax is commonly used as a phase change material (PCM) due to its excellent thermal storage properties. It is incorporated into various composites to improve their thermal conductivity and stability. Research has demonstrated the long-term thermophysical behavior of paraffin wax and paraffin wax/polyaniline (PANI) composites, highlighting their potential in thermal energy storage systems. This application is essential for developing efficient and sustainable energy storage solutions (Journal of Energy Storage, 2020).


• Aromatherapy and Insect Repellent Candles: Paraffin wax is used as a base material in the production of aromatherapy candles and insect repellent candles. Studies have compared the physical properties of palm wax and paraffin wax in these applications, showing that paraffin wax provides longer burn times and effective repellency against mosquitoes. This application is significant for creating functional candles that offer both therapeutic benefits and protection from insects (ISTA Online Technologi Journal, 2023).


• Hypergolic Rocket Fuels: Paraffin wax is explored as a component in hybrid rocket fuels. Research has focused on enhancing the hypergolic properties of paraffin wax-based fuels by incorporating additives such as metal nanoparticles. This application is vital for developing safer and more efficient rocket propellants, contributing to advancements in aerospace technology (Egyptian Journal of Chemistry, 2023).
