Device and method for preparing porous alumina microfiber based on microfluidic chip
The invention relates to a device and a method for preparing porous alumina microfibers based on a microfluidic chip. The preparation method comprises the following specific steps: mixing a base-phase mixed solution and a curing-phase mixed solution through a micro-reaction device, and heating to generate a polymerization reaction to obtain a microfiber green body; and cleaning, aging, drying and sintering the microfiber green body to obtain the porous alumina microfiber. The base phase mixed solution is composed of an alumina nano dispersion liquid, a prepolymer and a pore-foaming agent, and the pore-foaming agent is soluble starch; and the curing phase consists of an initiator, a catalyst and water. Soluble starch is selected as a pore-foaming agent, so that the aluminum oxide microfiber with a porous structure can be obtained. The porous alumina fiber is high in porosity and round in cross section, and can be applied to the fields of aerospace, purification and separation, biological scaffolds, sound absorption and shock absorption and the like.
本发明涉及一种基于微流体芯片的多孔氧化铝微纤维的制备装置和方法。具体步骤为：将基相混合液、固化相混合液通过微反应装置进行混合、加热发生聚合反应得到微纤维生坯；微纤维生坯经过清洗、陈化、干燥、烧结后得到多孔氧化铝微纤维。基相混合液由氧化铝纳米分散液、预聚物和致孔剂组成，致孔剂为可溶性淀粉；固化相由引发剂、催化剂和水组成。所述致孔剂选择可溶性淀粉，有助于得到多孔结构的氧化铝微纤维。多孔氧化铝纤维孔隙率较高，截面圆整，可应用于航空航天、净化分离、生物支架、吸声减震等领域。
