ABSTRACT This study investigates the correlation between rheological, morphological, and mechanical properties of biodegradable polylactic acid (PLA)/polycaprolactone (PCL) blends incorporating cellulose nanocrystals (CNCs). The research is motivated by need to improve compatibility immiscible polymers, such as PLA PCL, develop sustainable materials suitable for bio‐packaging applications. Despite their individual advantages, PCL suffer from poor interfacial adhesion incompatibility when blended, limiting application. addition CNCs renewable nanofillers can address these challenges enhancing improving material properties. In this view, were synthesized characterized, with AFM, TEM, XRD analyses confirming successful preparation. Various PLA/PCL containing different concentrations (0.25, 0.5, 1 wt%) prepared analyzed in terms morphology, rheology, results demonstrate a strong microstructure final performance. Mechanical testing revealed significant improvement tensile strength modulus, CNC‐0.5 sample highest 40.01 MPa modulus 1109.16 MPa, compared 26.63 909.71 neat blend. Rheological analysis showed an enhanced viscosity elasticity sample, attributed effective CNC dispersion localization, which improved compatibility. However, higher (1 led aggregation consequently inferior These suggest that significantly improves PLA, making more biomedical applications tissue engineering drug delivery.
