Abstract:The OPGS/PA-APP/PP composite with excellent flame retardancy and good mechanical properties has been prepared. The Organo palygorskite (OPGS) was introduced into the PA-APP/PP flame retardant composite. The OPGS loading on the performance of flame retardancy and mechanical properties of the composite were investigated by the limited oxygen index (LOI), vertical burning test (UL-94), thermogravimetric analysis (TGA), scanning electronic microscopy (SEM) and electronic universal testing machine. The experimental results showed that the addition of 2% of OPGS simultaneously increased flame retardancy of PA-APP/PP composite as well as the tensile strength and bending strength. In addition, the prepared samples could pass the V-0 rating in the UL-94 tests. The OPGS has obvious flame retardant synergistic effect in the IFR/PP system.

Abstract:With aniline，carbazole，indoline and iodobenzene as raw materials，we designed and synthesized a series of five new styryl triphenylamine derivatives.The synthesis method and the yields were discussed.

Abstract:Chiral stationary phase was the foundation and core of liquid chromatography. In this paper, cyclodextrin polymer (CDP) was synthesized through a simple condensation, and then bonded onto homemade silica microspheres to develop a novel chiral stationary phase. The reaction time, material ratio and reaction pathways were investigated in the process of the synthesis. And then scanning electron microscopy (SEM) was utilized to characterize its ball roundness. Blue tetrazolium method was applied to detect the content of the cyclodextrin. The result was 42.4 μmol/g, which is markedly higher than CD bonded silica gel. Finally, the product was packed with high pressure slurry method, and the chiral column was tested by liquid chromatography to separate chiral drugs. Meanwhile, the above β-CD and β-CDP were compared with ODS to resolve chiral drugs under the same chromatographic conditions. The result demonstrated that better separation was obtained by β-CDP bonded silica gel.

The results revealed that the intrinsic fluorescence of HSA could be successfully decreased by derivatives interactions. The experimental results were in agreement with molecular docking.
