【摘要】： 本文采用高压静电纺丝技术制备出低成本、单一分散的聚苯乙烯微球。通过调节电纺溶液浓度和高分子分子量过程参数,分析其对微球形态结构的影响。并在此基础上,将两种不同发光波长的CdSe量子点与聚苯乙烯高分子有效掺杂,利用静电纺丝方法制备了具有良好荧光性质的单色以及双色CdSe/PS复合微球。此类无机／有机功能材料应用领域正在迅速扩大,并逐渐成为高分子材料研究中的热点之一此外,我们设计组装了多喷头独立电场静电纺丝装置,并将其应用于构筑超疏水表面。多喷头静电纺丝技术实现了不同形态电纺产物的层层叠加,从而控制薄膜表面的粗糙度。由此方法,我们成功获得了具有一定机械强度的聚苯乙烯超疏水薄膜。这种多喷头静电纺丝技术克服了单一喷头纺丝产率低的缺点,为今后的大规模生产提供了可能。
[Abstract]:In this paper, low-cost, single-dispersed polystyrene microspheres were prepared by high voltage electrostatic spinning. By adjusting the concentration of electrospun solution and the parameters of molecular weight of polymer, the effect of electrospun solution on the morphology of microspheres was analyzed. On this basis, two kinds of CdSe quantum dots with different luminescence wavelengths were effectively doped with polystyrene polymer, and monochromatic and two-color CdSe/PS composite microspheres with good fluorescence properties were prepared by electrospinning method. The application field of this kind of inorganic / organic functional materials is expanding rapidly and has gradually become one of the hot spots in the research of polymer materials. In addition, we designed and assembled a multi-nozzle independent electric field electrostatic spinning device, and used it to construct superhydrophobic surface. The multi-nozzle electrospinning technology can control the surface roughness of the film by stacking the electrospun products with different forms. By this method, polystyrene superhydrophobic films with certain mechanical strength have been successfully obtained. This multi-nozzle electrostatic spinning technology overcomes the shortcoming of low spinning yield of single spinneret and provides the possibility for large-scale production in the future.
