Waste cutting emulsions are difficult to treat efficiently owing to their complex composition and stable emulsified structure.As an important treatment method for emulsions,chemical demulsification is faced with challenges such as low flocs-water separation rates and high sludge production.Hence,in this study,Fe3O4 magnetic nanoparticles(MNPs)were used to enhance chemical demulsification performance for treating waste cutting emulsions under a magnetic field.The addition of MNPs significantly decreased the time required to attain sludge-water separation and sludge compression equilibrium,from 210 to 20 min.In addition,the volume percentage of sludge produced at the equilibrium state was reduced from 45% to 10%.This excellent flocculation-separation performance was stable over a pH range of 3-11.The magnetization of the flocculants and oil droplets to form a flocculant-MNP-oil droplet composite,and the magnetic transfer of the composite were two key processes that enhanced the separation of cutting emulsions.Specifically,the interactions among MNPs,flocculants,and oil droplets were important in the magnetization process,which was controlled by the structures and properties of the three components.Under the magnetic field,the magnetized flocculant-MNP-oil droplet composites were considerably accelerated and separated from water,and the sludge was simultaneously compressed.Thus,this study expands the applicability of magnetic separation techniques in the treatment of complex waste cutting emulsions.

冰模板法用水作为成孔剂,已成为一种无污染且有前景的多孔材料制备方法.由水溶液制备的多孔聚合物通常耐水性较差,通过冰冻悬浮液可以制备疏水性多孔材料,但需要额外添加有机溶剂,易造成环境污染.基于此,本文提出了一种乳液冰冻光交联的方法.首先合成无乳化剂的光敏乳液,然后将乳液冰冻并通过光交联的方式固定由冰晶产生的孔结构,再将冰模板融化即可得到多孔聚合物材料.该制孔过程无需冰冻干燥,且光交联效率极高(几分钟内即可完成),有利于连续化生产多孔聚合物.此外,本方法具有较强的普适性和广阔的应用前景,通过不同乳液配方,可获得包括可拉伸的多孔材料、玻璃化转变温度可调的形状记忆多孔材料,以及具有隔热性能的多孔陶瓷等.

作为一种多功能软填料,液态金属(LM)乳液为制备基于导电水凝胶的多功能应变传感器带来了新机遇.然而,界面张力和密度巨大的LM难以以稳定乳液的形式存在.本文中,我们展示了一种利用阳离子纤维素纳米纤维(CCNFs)包覆LM液滴来稳定LM乳液的策略.通过将CCNF稳定的LM乳液与丙烯酸(AA)混合并引发其原位聚合,以及在聚丙烯酸(PAA)、LM液滴和CCNF之间形成可逆的氢键、离子配位键和静电交联,制备了一种导电水凝胶CCNF-LM-PAA.得益于PAA与CCNF之间形成的可逆氢键、离子配位键和静电结合作用,CCNF-LMPAA水凝胶具有良好的导电性(1.54 S m^(-1))、较高的拉伸强度和断裂伸长率、粘附性和快速自愈合能力.CCNF-LM-PAA水凝胶作为应变传感材料,具有超高应变灵敏度(应变系数高达16.2)、低应变检测极限(<1%)、短响应/恢复时间(107/91 ms)和良好的耐用性(300次循环).这些性能使得基于CCNF-LM-PAA水凝胶的应变传感器能够作为可穿戴电子器件用于监测各种人体活动.因此,利用CCNF稳定LM乳液引入静电结合作用,为提高基于LM乳液水凝胶的可穿戴电子器件的应变传感性能提供了一种实用的方法.

Colloidal lipid particles such as solid lipid nanoparticles and liquid crystalline nanoparticles have great opportunities as drug carriers especially for lipophilic drugs intended for intravenous administration. In order to evaluate drug release from these nanoparticles and determine their behavior after administration, emulsion droplets were used as a lipophilic compartment to which the transfer of a model drug was measured. The detection of the model drug transferred from monoolein cubic particles and trimyristin solid lipid nanoparticles into emulsion droplets was performed using a flow cytometric technique. A higher rate and amount of porphyrin transfer from the solid lipid nanoparticles compared to the monoolein cubic particles was observed. This difference might be attributed to the formation of a highly ordered particle which leads to the expulsion of drug to the surface of the crystalline particle.Furthermore, the sponge-like structure of the monoolein cubic particles decreases the rate and amount of drug transferred. In conclusion, the flow cytometric technique is a suitable technique to study drug transfer from these carriers to large lipophilic acceptors. Monoolein cubic particles with their unique structure can be used successfully as a drug carrier with slow drug release compared with trimyristin nanoparticles.

This article informs that the production of polymer emulsion in China has achieved a considerable progress in recent years. The annual output growth of polymer emulsion adhesive in China was 20% from 2001 to 2004 and being the highest level in the world. The output of vinyl acetate in China was 960000 tons in 2004, and import amount was around 147000 tons. There are more than 500 polymer emulsion producers in China. Most producers have small production scale, low technique level, low product quality and environment pollution, and can not actualize sustained development.

Separation of oil/water mixtures, especially for the emulsified oil/water mixtures, is important because of the frequent occurrence of oil spill accidents. Utilizing superwetting porous membrane has become a promising approach to separate either surfactant-free or surfactant-stabilized emulsions. Herein we report a facile and versatile strategy for preparing hydrophobic/under-oil superhydrophobic membranes by coating the skeletons of the membranes with the poly[（3,3,3- trifluoropropyl）methylsiloxane] （PTFPMS） nanoparticles. The obtained membranes could be used to separate various water- in-oil emulsions with high flux and separation efficiency. In addition, owning to the outstanding resistance of PTFPMS to the most organic solvents or oils, the modified membranes exhibited the excellent reusability and the antifouling properties that were critical in the practical applications. Many commercially available membranes can be modified by such a simple method.
