| 2 | Preparation and Characterization of Urea-formaldehyde Resin/reactive Montmorillonite Composites显示文摘The urea-formaldehyde resin/reactive montmorillonite composites were prepared by in situ polymerization. The reactive montmorillonite was prepared firstly by being ion exchanged with organic molecules and secondly by being grafted with silane coupling agent, which could be demonstrated by X-ray diffraction(XRD) and thermogravimetric analysis(TGA). Scanning electron microscopy(SEM) revealed that the morphology of the urea-formaldehyde resin/reactive montmorillonite composites were ellipsoid or columnar particles. Energy dispersive spectrometry(EDS) confirmed that the reactive montmorillonite was encapsulated by urea-formaldehyde resin. Differential scanning calorimetry(DSC) indicated that curing process of the ureaformaldehyde resin/reactive montmorillonite composites consumed more energy than pure urea-formaldehyde resin. Thermogravimetric analysis(TGA) showed that the thermal stability of the urea-formaldehyde resin/reactive montmorillonite composites improved compared to pure urea-formaldehyde resin. Furthermore, the reactive montmorillonites reduced the formaldehyde emission of the composites and increased the water resistance. Finally, the mechanism to prepare the urea-formaldehyde resin/reactive montmorillonite composites was proposed. | 陈世伟 卢旭晨 PAN Feng WANG Tizhuang ZHANG Zhimin | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，4： | 2 |

| 5 | Synthesis of SAPO-34 using metakaolin in the presence of β-cyclodextrin显示文摘SAPO-34 molecular sieves were synthesized by the addition of β-cyclodextrin(β-CD) as crystal growth inhibitor using metakaolin as silicon and aluminum sources. Properties of the obtained samples were characterized by XRD,SEM,N2adsorption–desorption,FTIR,XRF,EDX,NH293-TPD andSi MAS NMR. When β-CD was added,crystal size of the SAPO-34 crystals decreased. Variation of Si content from the crystal center to surface decreased while total Si content hardly changed.29 Si MAS NMR results showed that β-CD contributed to better Si dispersion and decreased the size of Si(4Si) patches. Moreover,the MTO(methanol-to-olefin) process was conducted to investigate the influence of β-CD on catalytic performance. The synthesized sample with molar ratio of β-CD/Al2O3 equaling 0.055 remained active for 610 min while the sample synthesized without β-CD for only 280 min,which indicates that the lifetime of catalyst synthesized with β-CD is greatly prolonged. | Chen Zhang Xuchen Lu Tizhuang Wang | 2015 | Journal of Energy Chemistry2015，24，4： | 1 |
| 6 | Effect of Reactive Nanoclays on Performances of PMMA/Reactive Nanoclay Nanocomposites显示文摘PMMA/reactive nanoclay nanocomposites were prepared by emulsion polymerization using two different reactive nanoclays. X-ray diffraction(XRD) and thermogravimetric analysis(TGA) results confirmed that the reactive nanoclays, kaolinite and montmorillonite, were obtained by the silylation reaction and the double bonds were grafted onto the edges and surfaces of the nanoclays. The presence of reactive nanoclays could increase the average molecular weights, the glass transition temperatures(Tg) and improve the thermal properties of nanocomposite. The tensile properties, Young's modulus, and the aging properties of the nanocomposite films were also enhanced while the light transmittance decreased. Furthermore, the nanocomposites with the reactive kaolinite presented better performances than that with the reactive montmorillonite. Finally, the action mechanism of the reactive nanoclays to the performances of PMMA/reactive nanoclay nanocomposites was proposed. | 陈世伟 卢旭晨 WANG Tizhuang PAN Feng ZHANG Zhimin | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，6： | 0 |
