Description:
The ZnO coated on the PLA (Polylactic acid) plate with the anti-ultraviolet and high microwave transmission property was fabricated. The particle morphology was measured by the scanning electron microscopy (SEM). The UV-spectrum was measured by the UV Spectrometer. The complex permittivity was measured using a vector network analyzer in 2-18 GHz and the transmission rate (S12) was calculated for the two materials respectively. In order to get the high transmittance property, the genetic algorithm was used to optimize the thickness of the composite and the weight content of the ZnO absorbent. The results showed that the ZnO coating had the good UV protection property, UPF could be estimated 45∼50 as the wavelength was 200∼400 nm, and as the weight content increased, the transmittance value decreased. The composites with thickness 0.1 mm ZnO coating and 1 mm PLA plate had the high transmission rate (larger than 0.95).
