[Abstract]:The anisotropic emulsion has attracted more and more research interest for researchers, mainly because of its special anisotropic structure endowed with its unique performance and application value of.Cerberus emulsion is a new type of anisotropy. The emulsion droplets with three different composition, micro phase independent of each other, which makes the topology the droplet is anisotropic, greatly expand the application of emulsion in the related fields. In this paper, a mixed preparation of Cerberus emulsion, Cerberus emulsion prepared by adjusting the related factors with different morphologies and using Cerberus emulsion as template to prepare anisotropic particles with controllable structure. This paper synthesized magnetic Cerberus emulsion through the selective doping of Fe203, making the Cerberus droplet with magnetic response. Under the action of magnetic field, Cerberus drops of controllable rotation, translation and orientation. In addition, we discuss the effect of emulsion compositions on magnetic Fe203 and the concentration of emulsion. The main research contents of this thesis are as follows: 1. to three immiscible oil as the dispersed phase, surfactant solution as continuous phase, one step prepared by mixing with VO (vegetable oil) / PFOEMA (2- (perfluorooctyl) ethyl methacrylate) /DMS/0.4%F127_ (AQ) Cerberus emulsion. The temperature and composition change control of Cerberus emulsion topology adjustment, including the relative position of each chamber of the liquid drop in circles, the curvature of each chamber between the size of the room space. In addition, the partial phase diagram under different temperature system research, determine the three-phase region under different temperature, in the three-phase region investigation composition effect on the topology of.2. Cerberus emulsion by copolymerization of monomer, immiscible with the oil as the dispersed phase, surfactant and water The solution for the continuous phase, one step prepared by mixing with ETPTA (ethoxylated trimethylolpropane acrylate three three (/FC-770) Perfluoroethers) /DMS (double -3- methyl allyl propyl methyl siloxane oxygen four /0.4%F127_ two) (AQ) (polyoxyethylene polyoxypropylene copolymer three block copolymer emulsion) Cerberus. Through the concentration of the surfactant, composition, temperature, emulsifying strength change control of Cerberus emulsion topology adjustment. Composition change of the realization of Cerberus drops of oil phase volume ratio control, change the emulsifying strength with the same structure of Cerberus particle size in micro emulsion / continuous and controllable nano scale regulation. Through the photopolymerization preparation of anisotropic particles, the morphology and maternal droplet. In an anisotropic particle preparation process, composition using emulsion and emulsion side strength The change successfully realized the regularity of regulation anisotropic particle morphology. The results show that the anisotropy of the particle composition changes with different morphology were prepared; emulsifying strength to achieve change regularity of regulation at the micron scale within the range of the anisotropy of the particle size. This method can be extended to a variety of the polymerizable monomer system, can be prepared a variety of different composition, anisotropic polymer microspheres morphology varied. Therefore, using Cerberus emulsion template preparation of anisotropic particles with morphology, diversity, wide range of particle size, mass production advantage, is expected to expand the application of.3. anisotropic particles in various fields of magnetic Fe_2O_3 particles selectively solubilization in ETPTA/HFE 7200 (Perfluorobutane ethyl ether) /SO (silicone oil) /0.4%F127_ (AQ) Cerberus droplet system, the Cerberus emulsion has magnetic control of magnetic response. The particle concentration, influence of magnetic particles on the stability of emulsion and morphology; by changing the Cerberus emulsion droplets in the phase composition, morphology and magnetic properties of Cerberus emulsion magnetic response. Using a vibrating sample magnetometer on magnetic properties and magnetic response of the emulsion magnetic emulsion. The results show that the doped dynamic stability of magnetic particles has higher Cerberus, selective solubilization of Fe203 particles in ETPTA does not affect the morphology of Cerberus droplet. In the magnetic field induced can achieve directional movement of Cerberus emulsion. In addition, the anisotropy of Cerberus droplets in the magnetic field can be achieved under rotation and orientation.
