项目摘要
1. Cooperative measurement of <zeta> -potenitalIn order to examine the extent of the agreement of <zeta> -values measured by electrophoresis method, the examination of <zeta> -values arised from the distinction of measurement apparatus and the difference among individuals of the workers for measurement carried out. As the sample for the measurement and the simple microspherical particle, monodisperse polystyrene (PS) and styrene/sodium styrenesulfonate copolymer [P(St/NaSS)] latices used. The results were as follows. The difference of <zeta> -value among measurement apparatus became considerably small and the value among the same group of measurement apparatus agreed extremely. The difference among individuals of the worker was not recognized. The extent of the agreement of <zeta> -value for the use of P(St/NaSS) latex was greater than that of PS latex. This suggests that the wettability of latex relates to the measurement of <zeta> -potential.2. Assignment investigationThe pzc of surface oxides on ultrafine particles of Fe and Ni were measured. The fine particle of Graphite fluoride known as a new compound with an ultra-low surface energy was prepared, being dispersed in water and the stability was investigated. The deposition of copolymer latices having hydrophilic groups and polymer hydrogel layer on fibers were investigated. Experimental data on the amount of enzyme molecule immobilized and the conformation of protein molecules adsorbed on the microcapsule membrane were analyzed using the equation. Coagulation and coalescence of oil-in-water emulsion with inorganic electrolytes were investigated and interpreted in terms of the modified DLVO theory. The detachment of particles from substractes in aqueous solution was investigated by using a well-defined flow of electro-osmosis. The analyses on the condition and the mechanism forming a new ordered arrays of latices were carried out.
1.为了<zeta>考察<zeta>电泳法测定的-值的一致性程度,<zeta>从测定仪器的区别和测定人员的个体差异两个方面进行了-值的检验。作为用于测量的样品和简单的微球颗粒,使用单分散聚苯乙烯(PS)和苯乙烯/苯乙烯磺酸钠共聚物[P(St/NaSS)]胶乳。结果如下。测量<zeta>仪器之间的差值变得相当小,同一组测量仪器之间的值非常一致。工人个体之间的差异没有得到承认。P<zeta>(St/NaSS)胶乳的-值的一致程度大于PS胶乳。这表明乳胶的润湿性与-电位的测定有关<zeta>.归属研究测定了Fe和Ni超微粒子表面氧化物的pzc。制备了具有超低表面能的新型化合物氟化石墨微粒,并将其分散于水中,研究了其稳定性。研究了含亲水基团的共聚物胶乳和聚合物水凝胶层在纤维上的沉积。利用该方程对固定化酶分子量和蛋白质分子在微胶囊膜上的构象进行了分析。研究了水包油型乳状液在无机电解质作用下的凝聚和聚结过程,并用改进的DLVO理论解释了这一过程。本文用一种明确的电渗流研究了水溶液中颗粒与基质的分离。对形成新的有序胶乳阵列的条件和机理进行了分析。
