Preparation and Properties of PLA/Nano-ZnO Composite

Abstract:

In order to study the impact of nanoZnO on the mechanical properties of PLA, nanoZnO modified with different surface treatment agents (titanium ester NDZ-201,silane coupling agent KH550 ) was added to PLA matrix. The samples were examined by fourier transform infrared (FT-IR) spectroscopy, mechanical properties and SEM. The results show that infrared spectra of nanoZnO modified with different treatment agents include two peaks at 2852cm^-1 and 2925 cm^-1, which are corresponding to C-H stretching vibration, peak at 1735cm^-1 which is corresponding to NH₂, and peak at 964cm^-1 which is corresponding to P-O-Ti.when the addition of nanoZnO reaches to 1wt.%, the tensile strength of PLA/ZnO nanocomposites have the maximum values of 47.43MPa, increase to 9.64% by pure nanoZnO. The mechanical properties of PLA/ZnO nanocomposites can be improved modified with different treatment agents, and the dispersion of nanoZnO has been significantly improved.
