To investigate the effect of different core-sheath thickness ratios of core-sheath TiO2/ZnO nanofibers on the photoelectric performance of dye sensitized solar cell, core-sheath TiO2/ZnO nanofibers with different thickness ratios was fabricated by coaxial electrospinning via controlling spinning core-sheath solution flow rate ratios. Field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD) were used to characterize the core-sheath nanofibers. The results revealed that the nanofiber is composed of wurtzite ZnO as sheath and anatase TiO2 as core. Then, the TiO2/ZnO core-sheath nanofibrous membranes acted as photo-anode material to assemble dye sensitized solar cells. At last, we found that when the skin core spinning flow rate ratio is 1:1, the diameter of core-sheath nanofibers is about 154 nm and core layer is about 90 nm in diameter，the dye adsorption amount is the largest and the DSSC based on the core-sheath nanofibers has the highest efficiency of 5.47%, it is 22% higher comparing with DSSC based on the TiO2 nanofibers.

In the experiment, the PVC-coated membrane material was use as the study object. The material was been irradiated for a long time under the UVB-313 ultraviolet fluorescence tubes. Under this artificial accelerated agering condition, the service properties was been studied. In the course of the experiment, macroscopic examination was applied to the surface color and mechanical properties of the material. The microstructure was analyzed through the Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM). The experiment shows that with the volatilization of plasticizer on the material surface, the Carbonyl Index (CI) first down and then up. The degree of ageing is gradually deepended, a large number of small crack appeared on the PVC film surface. Due to the PVC coating cracking, the breaking elongation of the PVC material increased significantly, but tensile strength hadn’t been changed much after the cumulative UV radiation energy reached 76.03×103 kJ/m2. This shows that with the deepening of ageing, the adhesion effect of PVC coating to the polyester fabric is getting smaller.

White colors comprise approximately 3% of the total volume of CIELAB color space, but the relative importance of white materials is much larger than perhaps the small volumetric sector that represents white in the CIELAB color space. Numerous fiber materials contain yellowish impurities which are natural or formed in production. Such yellowish impurities significantly impair materials' whiteness. Hence, chemical bleaching and fluorescent whitening are often performed to improve materials' whiteness. In order to increase production effectiveness of white materials, researchers have developed whiteness indexes based on visual evaluation of white materials for instrumental measurement of whiteness. However, the instrumental measurement has been found to be not so accurate for whiteness evaluation, especially for measuring fluorescent whiteness. This paper mainly discussed the correlation between the instrumental measurement and the visually perception of fluorescent whitened textiles, and highlighted the possible factors affecting the instrumentally measured whiteness of fluorescent whitened textiles. A research project was proposed to optimize the correlation between the instrumental measurement and the visually perception of fluorescent whitened textiles and thus to improve the accuracy of the instrumentally measured whiteness of fluorescent whitened textiles. This paper provides new insight into the whiteness evaluation of fluorescent whitened textiles by enhancing the correlation between the instrumental measurement and the visually perception of fluorescent whitened textiles.
