大孔微珠是通过微流控制备负载二氧化硅的聚合物微滴，然后通过选择性蚀刻去除致孔剂来合成的。在流动聚焦微反应器中制备微滴，以确保单分散性以及致孔剂负载均匀。研究了致孔剂尺寸和聚合物网络密度对微珠孔隙率和有效模量的影响。
Macroporous microbeads are synthesized by microfluidic production of silica-loaded polymeric microdroplets followed by porogen removal via selective etching. Microdroplets are produced in a flow-focusing microreactor to ensure monodispersity with uniform porogen loading. Effects of porogen size and polymer network density on the porosity and effective modulus of the microbeads are studied.
