摘要/Abstract

摘要：

首先合成氨基封端的超支化聚芳醚酮(NH₂-HPAEK), 然后以NH₂-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NH₂-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.

关键词: 超支化聚芳醚酮, 空心多孔微球, 交联反应

Abstract:

Amino-terminated hyperbranched polyaryletherketone(NH₂-HPAEK) was synthesized. Then the hollow/porous microspheres with NH₂-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 NH₂-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 NH₂-HPAEK and aldehyde groups of glyoxal. The crosslinked hollow/porous microspheres have structural stability and are suitable for use in harsh environments.

Key words: Hyperbranched polyaryletherketone, Hollow/porous microsphere, Crosslinked reaction
