Figure 5. Tensile properties <strong>of</strong> the composites: (a) tensile modulus; and (b) tensile strength.<br />
From the 3rd step, the main chemical component is PLA-Si-O-talc.<br />
In terms <strong>of</strong> tensile strength, remaining R-Si-(OH) 3 and R-Si-(OMe) 3 have<br />
an interaction with PLA and WF, interfering the bonding potential <strong>of</strong> PLA-<br />
Si-O-talc. Therefore, the tensile strength at 3 wt% silane was significantly<br />
lower than that at 1 wt% silane level.<br />
