Abstract:

Dynamically vulcanised nanocomposite thermoplastics (TPVs) based on poly (lactide) (PLA) or natural rubber (NR) are prepared through a dynamic curing process. The crosslinked NR phase exhibits a continuous network structure embedded in the PLA phase, which differs from the conventional plastic/rubber system with an "island-sea" morphology in which vulcanized rubber particles are dispersed in the plastic matrix. Its internal interfacial compatibility was confirmed by SEM analysis. Also, CNC has been used as a stabilizer additive to improve the mechanical properties of PLA/NR thermoplastic vulcanizate (TPV). To achieve homogeneous dispersion of CNC, melt mixing method was used. The Mechanical properties were also improved by CNC incorporation, which increased from 14% of the unfilled TPV to 70% of the sample with 1.5 phr CNC. The "green" raw materials and excellent shape memory properties of PLA/NR/CNC prepared from the dynamic curing process are expected to open up a wide range of potential applications in the fields of smart medicine.
