<p>The rapid evolution of the porous materials industry has underscored the crucial need for advanced materials capable of enhancing the performance, safety, and environmental sustainability. This study focuses on the development of novel porous cellulose acetate (CA) for various applications, employing gas pressure methods to optimize properties such as porosity, thermal stability, and electrolyte wettability. Through a comprehensive analysis of the effects of various additives (glycerin, lactic acid, and glycolic acid) on the fabrication and performance of CA, this research aims to address the inherent limitations of traditional porous materials. Our experimental findings reveal that the gas pressure technique, coupled with specific additive incorporation, significantly influences the porosity and thermal properties of CA porous materials, enhancing their performance metrics. This study not only contributes to the advancement of porous materials technology but also aligns with the principles of green chemistry by utilizing biodegradable, renewable materials in the production of highly thermally stable porous materials. Our work heralds a new era in porous materials design, characterized by improved energy storage solutions and reduced environmental impact.</p>
