Three kinds of CB with different self-networking capabilities were used to tailor the phase morphology of PLA/PU blends.
CB with high self-networking capability could lead to an easier formation of more stable co-continuous-like structure.
The kinetics of CB self-networking in PLA/PU blends was studied by rheology.
The rheology-self-networking of fillers-phase morphology triadic correlation in fillers-filled polymer blends was established.
