采用PEI（聚乙烯亚胺）添加剂控制双射流反应结晶技术，制备了粒径分布窄、单分散、无团聚的SrSO4微颗粒。PEI在成核前与锶离子络合，成功抑制了快速/连续成核，实现了成核与生长的完美分离。我们的想法是获得具有理想尺寸分布的细颗粒，这将为提高高价值材料的性能提供新的潜力。
A controlled double-jet reactive crystallization technique using a PEI (polyethylenimine) additive has been conducted to produce agglomeration-free micro-particles of SrSO4 with narrow and mono-dispersed size distributions. PEI successfully inhibits rapid/continuous nucleation due to a complexation with strontium ions before nucleation occurs, and enables realization of perfect separation of nucleation and growth. Our idea to obtain fine particles with desired size distributions will introduce a new potential for contributing to enhance high-valued material properties.
