摘　　要：首先合成氨基封端的超支化聚芳醚酮(NH_2-HPAEK),然后以NH_2-HPAEK四氢呋喃溶液和聚乙烯醇(PVA)水溶液分别作为分散相和连续相,借助溶剂挥发法制备以NH_2-HPAEK为核、PVA为壳的空心多孔微球;通过氨基与乙二醛的交联反应,实现空心多孔微球结构的稳定化,进而满足其在一些特定环境下的使用要求.Amino-terminated hyperbranched polyaryletherketone(NH 2-HPAEK)was synthesized.Then the hollow/porous microspheres with NH 2-HPAEK as core and polyvinyl alcohol(PVA)as shell were prepared by the solvent-volatilization method,in which PVA aqueous solution was used as the continuous phase,and NH 2-HPAEK tetrahydrofuran solution was used as disperse phase.Finally,the structure of the hollow/porous microspheres was fixed by the crosslinking reaction between the amino groups of NH 2-HPAEK and aldehyde groups of glyoxal.The crosslinked hollow/porous microspheres have structural stability and are suitable for use in harsh environments.
