Paragraph starter
The incorporation of nanofillers into thermoplastic starch (TPS) presents a significant opportunity to enhance mechanical properties such as modulus and tensile strength, as evidenced by research into materials like montmorillonite and cellulose-based nanocomposites. However, designers must be aware that this often leads to a reduction in elongation at break and a decrease in optical transparency, necessitating a careful balance between performance requirements and aesthetic considerations. Furthermore, the successful integration of these nanofillers is highly dependent on their compatibility, dispersion, and distribution within the TPS matrix, which can be a significant manufacturing challenge.
