    • 摘要: 在遇到致密碳酸盐岩储层时,由于地层情况和管路摩阻的双重影响,反应为施工井口泵压的升高,导致无法提升施工排量,形成酸蚀裂缝的缝长短,为了解决施工过程中酸压工作液摩阻高的问题,本文通过合成一种反相乳液型低摩阻胶凝剂,并复配酸化用缓蚀剂、铁离子稳定剂、转相剂等辅剂制得胶凝酸工作液,实验数据表明:20%盐酸+2.5%低摩阻胶凝剂+2.5%酸化用缓蚀剂+1%铁离子稳定剂+1%粘土稳定剂+1%酸化用助排剂+1%酸化用转相剂,该体系胶凝酸在常温、170s^(-1)下表观粘度为37.5mPa·s,在140°C老化1h后粘度为30mPa·s,140°C缓蚀速率为29.0739g/(m^(2)·h),2.5%低摩阻胶凝剂水溶液的降阻率为75.17%,能够有效降低酸化工作液在泵注施工中的摩擦阻力。

    • 摘要: We established a modified breath figure( BF) method using inverse emulsion as casting solution to achieve directed assembly of water-soluble components with the BF arrays. It is a one-step technique with great ease of fabricating regular arrays of biomolecules via self-assembly. To be specific, we constructed a hybrid structured film made from polylactic acid ( PLA )/chitosan ( CS )/bovine serum albumin ( BSA ) mixing emulsion. CS particles were synthesized to serve as stabilizers for the inverse emulsion of water-in-oil type and BSA was selected as model protein to be carried within the emulsion water droplets. It has been proved that the CS particles could not only effectively contribute to stabilize the inverse emulsion, but also be able to improve the regularity of the obtained BF arrays. Furthermore, the influencing factors of BSA concentration and water-to-oil ratio were carefully tuned to study their effect on the obtained surface morphology. The results showed that the increase of the BSA concentration and the water-to-oil ratio would both compromise the regular arrangement of the surface pore arrays. But if the concentration and ratio were both increased to a high level, the regular BF arrays would reappear. We tagged the BSA with fluorescent probe to track the assembled morphology of the BSA within the porous polymer matrix. And 3D ring-like arrays of the fluorescent protein were observed under confocal microscope, indicating the success of obtaining the protein arrays via a one-step technique.%通过将传统水滴模板法中的单相成膜液改造为反相乳液体系,引进乳液水滴来加载蛋白质组分,实现了对亲水组分直接实施水滴模板法从而获得其阵列组装结构.利用壳聚糖纳米粒子作为皮克林反相乳液的乳化剂制备了稳定的反相乳液体系,并进一步得到聚乳酸/壳聚糖/牛血清白蛋白的杂化蜂窝状多孔薄膜,考察了壳聚糖粒子对于乳液稳定和所制备多孔阵列结构形貌的影响,研究了加入蛋白质浓度和乳液中的水相/油相比例对于所成膜孔形貌的影响,利用荧光标记蛋白质跟踪确认基于蜂窝状多孔阵列结构上的图案化蛋白质阵列组装形貌.

    • 摘要: 以丙烯酰胺(AM)和甲基丙烯酰氧乙基三甲基氯化铵(DMC)为单体,失水山梨糖醇脂肪酸酯(Span 80)和失水山梨醇单油酸酯聚氧乙烯醚(Tween 80)为乳化剂,液体石蜡为油相,2,2′-偶氮二异丙基咪唑啉二盐酸盐(VA-044)为引发剂,研究AM与DMC反相乳液聚合动力学,反相乳液聚合速率方程为Rp= k[M]2.12[I]0.55[E]0.65, AM与DMC反相乳液聚合表观活化能为80.65 kJ·mol-1.通过反相乳液聚合速率随时间的变化关系得出其成核机理倾向于单体液滴成核.用Fireman-Ross法研究了共聚单体竞聚率,分别为rAM= 0.23、rDMC= 1.93,AM与DMC在聚合物链上发生无规共聚反应.单体量增大、引发剂量减少、乳化剂量增大、聚合温度降低均使共聚产物的特性黏数增大.%Inverse emulsion polymerization kinetics of acrylamide (AM) and 2-methylacryloylxyethyltrimethyl ammonium chloride (DMC) has been investigated by using the mixture of sorbitan monooleate (Span 80) and polyethylene glycol sorbitan monooleate (Tween 80) as the composite emulsifier, liquid paraffin as the oil phase and 2,2′-azobis[2-(2-imidazolin-2-yl) propane]-dihydrochloride as the initiator. The rate equation of AM and DMC inverse emulsion polymerization could be represented as Rp= k[M]2.12[I]0.55[E]0.65, and the apparent activation energy of AM and DMC inverse emulsion polymerization was 80.65 kJ·mol-1. Relationship of reaction rate change in AM and DMC inverse emulsion polymerization with time indicated that the nucleation mechanism tended to droplet nucleation. Monomer reactivity ratios of AM and DMC were determined as rAM= 0.23,rDMC= 1.93 by Fineman-Ross methods. The results showed that random copolymerization of AM and DMC occurred on the polymer chains. The intrinsic viscosity of copolymer could be increased by enhancing the content of monomer, decreasing the dose of initiator, increasing the amount of emulsifier and reducing the reaction temperature.

    • 摘要: 为了优化水溶性物质微胶囊化工艺,并探究影响因素,在W/O反相乳液体系中,采用原位聚合法,通过自由基聚合成功制备了具有生物相容性的聚甲基丙烯酸甲酯(PMMA)为壁材、水为囊芯的微胶囊,并研究芯壁比、油水体积比、甲基丙烯酸(MAA)、交联剂甲基丙烯酸烯丙酯(AMA)对微胶囊性能的影响;通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、激光散射粒度分布分析仪(LSPSDA)、差示量热分析(DSC)和热重分析(TG)对微胶囊的形貌、结构、粒度分布、包覆率、热焓值及热稳性进行了分析.结果表明:微胶囊近似球形,具有核壳结构,粒径主要分布在0.5~1.5μm之间;芯壁比为1:1时微胶囊的形貌最为规则,最佳油水相体积比为10:1;加入交联剂和甲基丙烯酸的微胶囊包覆率分别提高了20%和30%左右,壁材中添加交联剂和甲基丙烯酸有助于提高包覆率.%In order to optimize the microencapsulation process of water-soluble substances, and explore the influencing factors, microcapsules containing water were prepared by in-situ polymerization in inverse emulsion system with biocompatible poly (methyl methacrylate) as shell by free radical polymerization. The influence of core-shell ratio, volume ratio of oil to water, methacrylic acid and crosslinking agent on the properties of microcapsules were discussed. The morphologies, core-shell structure, particle size distribution, encapsulation efficiency, and thermal stabilities of the microcapsules were characterized by scanning electron microscopy(SEM), transmission electron microscope(TEM), laser scattering particle size distribution analyzer(LSPSDA), differential scanning calorimetry(DSC), and thermal gravimetric analysis(TG). Results showed that the spherical microcapsules had a core-shell structure, and the distribution of particle size was in 0.5-1.5μm. The morphology of the microcapsules was the most regular when the ratio of the core-shell was 1:1, the best volume ratio of oil to water phase was 10:1. The encapsulation efficiency increased by 20% and 30% respectively by adding crosslinking agent and methacrylic acid. The addition of crosslinking agent and methacrylic acid can improve the encapsulation effi-ciency significantly.
