Method & Evidence

AimTo develop bio-elastomers with tunable elasticity, high strength, and cytocompatibility using a dynamic vulcanization strategy.

MethodExperimental material synthesis and characterization.

ProcedureBiobased polyester elastomer (BPE) and polycaprolactone (PCL) were melt-blended in the presence of a crosslinker. Dynamic vulcanization was employed, leading to phase inversion where the BPE was crosslinked and dispersed within the PCL matrix. The resulting bio-TPV was then characterized for its mechanical properties, processability, reprocessability, and cytocompatibility.
