Method & Evidence

AimTo investigate the impact of MCC and NFC fillers on the thermo-mechanical properties and biodegradation rates of bio-based PBS composites for wood-like applications.

MethodExperimental research

ProcedureFive different compositions of PBS composites were prepared using melt blending with varying ratios of MCC and NFC fillers, up to a total loading of 40 wt%. Mechanical properties were assessed using tensile testing (Young's modulus) and dynamic mechanical analysis (storage modulus). Thermal properties were analyzed using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Morphology was examined using scanning electron microscopy (SEM), and surface properties were evaluated through contact angle measurements. Biodegradation was tested under composting conditions.
