蛭石层状膜的制备及有机溶剂纳滤性能

受全球能源形势与环境问题影响,新型膜分离技术尤其是二维层状膜在分离领域展现出广阔的应用前景。然而,目前使用的二维纳米材料化学环境相对复杂,且膜制备成本高昂,限制了其工业化推广。天然蛭石廉价易得,剥离简单,表面只含有硅羟基且其含量易于调控,可精确调控所制备层状膜层间亲疏水性,实现有机溶剂的高效渗透和极性与非极性溶剂的高效分离。研究发现：蛭石层状膜展现出优异的极性溶剂分子传递能力,而非极性溶剂则相对较低,其中乙腈分子渗透性高达1650L/（m²·h·bar)（1bar=0.1MPa）,甲苯分子渗透性仅为37.8L/（m²·h·bar),乙腈与甲苯的分离因子高达43.6,展现出优异的分子分离性能。本文所制备蛭石层状膜具有1.36nm的规则平直层间传递通道,对分子动力学直径大于层间距的结晶紫（1.5nm）、亮蓝（1.6nm）、酸性黄14（1.9nm）等染料分子的截留率均大于90%,截留性能优良。同时,蛭石层状膜具有良好的压力循环稳定性及抗污染能力, 展现出巨大的分离应用潜力。     

Studies on self‐assembly and characterization of polyelectrolytes and organic dyes

Four polyelectrolyte complexes were formed through self‐assembly of poly‐N‐ethyl‐N,N‐(dimethylamino)ethyl methacrylate (PEDEM) and poly‐N‐ethyl‐4‐vinylpyridinium (PEVP) cations with methyl orange (MO) and metanil yellow (MY) anions in water. The FTIR spectra showed that the assembly was formed chiefly through electrostatic force and hydrophobic interaction between polyelectrolytes and organic dyes without new bonds emerging. The fluorescence spectra revealed that the emission waves of the complexes of PEDEM–MY and PEDEM–MO in alcohol were blue‐shifted in comparison with that of dyes in alcohol, and the emission waves of the PEVP–MY and PEVP–MO_ complexes in alcohol were red‐shifted in comparison with that of dyes in alcohol. The structure of the complexes in the solid state were also investigated by DTA and X‐ray diffraction experiments. It could be proved that the complexes were new materials formed through weak interactions. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 87: 369–374, 2003

Performance,structure-property relationship and biodegradability of poly(lactic acid)/amide ammonium acetate organic vermiculite intercalation nanocomposites

ABSTRACT

The ammonium acetate organic vermiculite (A-OVMT) was synthesized with phenylenediamine and ammonium acetate by solution intercalation. Then, poly(lactic acid) (PLA)/A-OVMT nanocomposites were prepared by the melt intercalation. Performance, structure-property relationship and biodegradability of PLA/A-OVMT nanocomposites were investigated, which showed that A-OVMT acted as heterogeneous nucleation in PLA matrix. The tensile strength, elongation at break, and impact strength of PLA/A-OVMT (0.3 wt%) nanocomposites had an increase of 8.43%, 4.87%, and 45.92%, respectively. Moreover, the limit oxygen index of PLA was enhanced to 23.50%, and its vertical combustion grade of was up to UL-94 V-2. However, A-OVMT slightly inhibited the biodegradability of PLA.     

铁掺杂氧化锌制备及对有机染料的光催化降解

采用沉淀法制备铁掺杂的纳米氧化锌。通过粉末X射线衍射（PXRD）和红外光谱（IR）对样品及其前驱体进行表征;采用分光光度计测定样品光催化降解有机染料的效果;用扫描电子显微镜（SEM）观测样品的表面形貌。实验结果表明,铁掺杂的氧化锌比纯氧化锌具有更高的催化活性和催化效率。这归因于铁均匀分布在氧化锌中,避免了氧化锌纳米粒子间的团聚,改善了氧化锌表面的性质,在降解有机染料过程中与有机染料大面积接触,对甲基橙和亚甲基蓝具有良好的降解效果,是一种有潜力的光催化降解材料。

Match prediction of highly fluorescent colors

Color formulation of fluorescent materials is not feasible with the usual methods used for nonfluorescent colors. Realizing the need for certain textiles that are dyed with fluorescent colorants, a technique was developed based on using certain dual-monochromator measurements of the spectra of fluorescent colorants. to accomplish this formulation, a new spectral quantity independent of illuminant was developed for all fluorescent colorants. This is termed RELEX, which describes the relative excitation of the colorant. When this quantity is weighted by the spectral power distribution for a specific illuminant and factored for absorption by all ingredients in a mixture of colorants, the proper fluorescent emission is obtained, which can be added to the spectral reflected radiance factor, β_s, for that mixture. Consequently, match prediction can be done for spectral radiance factor, β_T, curves of fluorescent materials using an iterative estimation algorithm.     

Polymer‐derived ceramic aerogels as sorbent materials for the removal of organic dyes from aqueous solutions

Polymer‐derived SiC and SiOC aerogels have been synthesized and characterized both from the microstructural point of view and as sorbent materials for removing organic dyes (Methylene Blue, MB, and Rhodamine B, RB) from water solutions. Their adsorbent behavior has been compared with a polymer‐derived SiC foam and a commercial mesoporous silica. The aerogels can efficiently remove MB and RB from water solution and their capacity is higher compared to the SiC foams due to the higher surface area. The SiOC aerogel remains monolithic after the water treatment (allowing for an easy removal without the need of a filtration step) and its maximum capacity for removing MB is 42.2 mg/g, which is higher compared to the studied mesoporous silica and many C‐based porous adsorbents reported in the literature. The reason for this high adsorption capacity has been related to the unique structure of the polymer‐derived SiOC, which consists of an amorphous silicon oxycarbide network and a free carbon phase.
