Uv Protective Properties

A novel ZnO nanoparticles aqueous solution was prepared through a one-step reaction between a modified hyperbranched polymer-PNP and zinc nitrate. During the reaction process, PNP not only acted as the reagent to produce ZnO nanoparticles, but also controlled the size of the synthesized ZnO nanoparticles and stabilize them after reaction. The size of ZnO nanoparticles were about 6 nm with narrow size distribution. Then the ZnO nanoparticles were utilized for the functional finishing of cotton fabrics by in situ generation and deposition method. Scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) measurements confirmed the ZnO nanoparticles coated on the cotton fibers. The treated cotton fabrics exhibited excellent UV protective properties and antibacterial activities. When the ZnO content in cotton fabric was 2.23 %, the UPF value of treated cotton fabric reached 114.4 and the bacterial reduction rates againstStaphylococcus aureus(S. aureus) andEscherichia coli(E. coli) both exceeded 98 %.

Abstractβ-FeSi2 is a promising material for the application of various electronic, optoelectronic and energy devices. We present here the semiconducting properties of β-FeSi2 films on Si(100) substrate prepared by laser ablation method. Samples were grown using poly-crystalline bulk β-FeSi2 prepared by horizontal gradient freeze method. For the monitoring of growth, in-situ observation of ablation plume was made through fluorescence spectroscopy. Reflection of highenergy electron beam diffraction (RHEED) was also made in-situ to see the surface morphology. Characterization of the films by X-ray diffraction presented purely P3(220) orientation. Raman scattering measurements at room temperature also indicated that the grown films are semiconducting β-FeSi2. Optical absorption spectra at room temperature showed absorption coefficient higher than 105 cm−1 above the band-gap (˜1.2 eV). It was revealed that high quality semiconducting β-FeSi2 films can be fabricated by laser ablation method without post-annealing.
