This research endeavors to manipulate the mechanical and thermal characteristics by optimizing the polymerization conditions of urethane foam while integrating cellulose nanomaterials (CNMs), known for their eco-friendly properties, through chemical reaction induction. Within the domain of urethane materials, foam variants, notably rigid urethane foam as an insulator and flexible urethane foam employed in memory foam and interior applications, are of particular interest.
Rigid urethane foam, primarily employed in construction and cooling sectors as insulation, is now gaining prominence in advanced insulation techniques for the transport and storage of liquefied natural gas (LNG). Its lighter weight and superior mechanical strength potential offer economic advantages by potentially reducing the material quantities required. Enhancing mechanical robustness while simultaneously reducing thermal conductivity holds promise for space optimization in LNG storage or transport contexts where superior thermal insulation and mechanical properties are paramount.
The surge in demand for environmentally sustainable construction materials aligns with the integration of cellulose, a sustainable alternative, to modulate properties. In addition, we need lighter materials. Glass fiber-reinforced insulation, prevalent in LNG transport, possesses a density of 2.5 g/cm³, significantly higher than the urethane foam material under consideration.
Flexible urethane foam, notably used in automotive seat interiors, demands heightened durability and toughness to withstand long-term usage and repeated stress conditions.
This study's focal objectives involve the development of eco-friendly cellulose nanomaterials and the refinement of urethane compositions to generate nanocomposite foams. The most important goal is to manipulate the physical properties of these nanocomposites through an intricate understanding and advancement of urethane reaction mechanisms. The study's scope encompasses thorough investigations into nanomaterials, polymerization processes, and optimized mixing methodologies to achieve desired material enhancements.
