| Abstract Scope |
Polylactic acid is a biocompatible, and biodegradable thermoplastic. It is renewable being produced by bacterial fermentation of potatoes, sugarcane, or corn starch. PLA has can be processed easily but its low toughness and thermal stability are setbacks in some applications. This study focuses on synthesis of Parquetina nigrescens pod nanoparticles (PNPNP) as reinforcements in the PLA to engineer new nanocomposites for biomedical applications. TEM result indicates an average size of 14.14 nm of the PNPNP. Fourier Transform Infrared Spectrograph establishes a reduction in the amount of light transmitted by the PLA due to PNPNP additions with changes in the wavenumbers of the observed peaks affirming formation of new compounds due to interactions of the PLA molecules and PNPNP. X-ray diffractograms reaffirms new compound formations. Moreover, there are enhancements in mechanical properties up to 3% by weight of PNPNP addition to the PLA with about 92% improvement in the impact toughness. |
