Abstract PEI-based network materials with polyhedral oligomeric silsesquioxane (POSS) particles as a cross-linker were prepared by the chemical amine/epoxide reaction of PEI and glycidyl-POSS. Glycidyl-POSS is a hybrid molecule with an inorganic silsesquioxane at the core and organic glycidyl groups attached at the corners of the cage. POSS molecules were homogeneously dispersed as the crosslinking point in PEI matrix. These hybrid network materials were fabricated with not only different weight ratio of POSS to PEI but also 1,4-butanediol diglycidyl ether (BDE) as a cross-linker instead of POSS to confirm the effect of POSS on the CO2 capture performance and thermal stability.

使用聚乙烯亚胺和缩水甘油基-POSS 制备用于 CO2 吸附的混合网络材料

摘要 通过PEI和缩水甘油基-POSS的化学胺/环氧化物反应，制备了以多面体低聚倍半硅氧烷(POSS)颗粒为交联剂的PEI基网络材料。缩水甘油基-POSS 是一种杂化分子，其核心是无机倍半硅氧烷，笼角连接有有机缩水甘油基。POSS 分子作为交联点均匀分散在 PEI 基质中。这些混合网络材料不仅使用不同的 POSS 与 PEI 的重量比制造，而且使用 1,4-丁二醇二缩水甘油醚 (BDE) 作为交联剂代替 POSS，以确认 POSS 对 CO2 捕获性能和热稳定性的影响.
