摘要
具有不同形貌的聚合物微球在生物和材料等领域应用广泛。目前,越来越多的研究选择以微流控技术为平台来制备聚合物微球。本文报道了一种基于微流控技术,通过调节表面活性剂的HLB值来制备具有拓扑结构磁性聚合物微球的方法。结果表明,不同表面活性剂的HLB值能够调控液滴的演变行为和目标微球的形貌特征;同时,该方法具备一定的普适性,可作为制备聚合物微球的有效补充手段。
Polymer microspheres with different morphologies are widely used in biology and materials science. At present,an increasing number of researchers choose to use microfluidic technology as a platform to prepare polymer microspheres. Here,a method based on microfluidic technology to prepare magnetic polymer microspheres with topological structure by adjusting the HLB value of the surfactant was reported. The results showed that the HLB value of different surfactants can regulate the evolution behavior of droplets and the morphology of target microspheres. This method has certain universality. It can be used as an effective supplement to the preparation of polymer microspheres.
