Abstract:
The research studies the role of a plasticizer (206 3NL), an oligomeric polyadipate and of a nucleating agent, an aromatic sulfonate derivative (LAK301) on the mechanical behavior of poly-lactic acid (PLA) through Tensile tests, Charpy Impact tests. The results show that LAK301 acted as a nucleating agent and 206 3NL was a compatible plasticizer for PLA. In fact, in the binary include 1 wt% of nucleating agent (LAK301) the Young’s modulus increased to 5.2 GPa in respect to pure PLA (3.2 GPa), beside in the presence of 15wt% of plasticizer (206 3NL) the elongation at break of PLA reached 285%. Furthermore, the impact strength was also slightly improved when the plasticizer was added
