摘要:
基于液滴成型技术,在同轴微流体装置中,通过对连续相流速、黏度以及表面活性剂的调变,获得了球形、棒状、子弹头形及瓜子形貌的油包水(W/O,W为水,O为油)乳液液滴。在丙烯酰胺-聚乙二醇(AM-PEG)体系中将AM聚合成聚丙烯酰胺(PAM),PAM与PEG分相形成以PAM水凝胶为核、PEG水溶液为壳的核/壳结构液滴,制得了对应形貌H/W/O(H为水凝胶)结构的PAM/PEG多重乳液液滴。当酯类、烃类和硅油类油相分别作为内、外侧油相时,得到的O/W/O液滴形貌与使用相同外侧油相时制得的W/O液滴形貌是对应的。聚合后,由于每种油相的极性不同,造成油水界面处分相现象的差异,可制得对应形貌的O/H/O、O/W/H/W/O、O/H/W/O及O/W/H/O结构的多重乳液液滴。
Abstract:
Based on droplet-based microfluidics,water in oil(W/O)emulsions with spherical,rod,bullet and pumpkin seed morphology were formed in a coaxial microfluidic device through adjusting velocity,viscosity, and surface active agent of continuous phase.After polymerization,acrylamide(AM)in AM-polyethylene glycol(PEG)system was transformed to polyacrylamide(PAM)hydrogel.Then,hydrogel in water in oil(H/W/O)structure of PAM/PEG multi-emulsion droplets with PAM as core and PEG aqueous solution as shell were formed.When esters,hydrocarbons and silicone oils were used as inner and outer oil phases,the morphologies of O/W/O emulsions were similar to W/O emulsions using the same outer oil phase.After polymerization,because of the different polarity of oil phases,the phase separation behaviors were different on oil-water interface.Thus,O/H/O,O/W/H/W/O,O/H/W/O and O/W/H/O structure multi-emulsion droplets with different morphologies were prepared.
