Title (EN) PREPARATION METHOD FOR POLYSULFONE NANOPOROUS POLYMERS
(FR) PROCÉDÉ DE PRÉPARATION DE POLYMÈRES NANOPOREUX DE POLYSULFONE
(ZH) 聚砜类纳米多孔聚合物的制备方法
Abstract:
(EN) A preparation method for polysulfone nanoporous polymers comprising: immersing polysulfone copolymers and polar copolymers in a complex swelling agent for at least 1 min at room temperature, in which the complex swelling agent is a "solvent pair" obtained by mixing a solvent A with a solvent B, the solvent A has a high affinity to polysulfone polymers, and the solvent B has a high affinity to polar polymers; and taking the treated copolymers from the complex swelling agent and drying the same to remove the solvent to obtain the polysulfone nanoporous polymers. The pores of the polymers from the method are uniform, the pore size distribution is a range of 10-100 nm, and the pores connect with each other. The pore structure has high thermal stability and high mechanical stability, and the pore wall is highly hydrophilic because the polar polymer molecular chain covers the same. Further, the method is suitable for copolymers with different sizes and shapes, is easy to operate and easy to implement at scale.
(FR) La présente invention concerne un procédé de préparation de polymères nanoporeux de polysulfone qui comprend les étapes consistant à : immerger des copolymères de polysulfone et des copolymères polaires dans un agent gonflant complexe pendant au moins 1 minute à température ambiante, l'agent gonflant complexe étant une "paire de solvants" obtenue par mélange d'un solvant A avec un solvant B, le solvant A a une affinité élevée vis-à-vis de polymères de polysulfone, et le solvant B a une affinité élevée vis-à-vis des polymères polaires ; et prendre les copolymères traités de l'agent gonflant complexe et les sécher pour éliminer le solvant pour obtenir les polymères nanoporeux de polysulfone. Les pores des polymères issus du procédé sont uniformes, la distribution de la taille des pores est dans une plage de 10 à 100 nm, et les pores se connectent les uns aux autres. La structure poreuse présente une stabilité thermique élevée et une stabilité mécanique élevée, et la paroi poreuse est hautement hydrophile parce que la chaîne moléculaire polymère polaire la recouvre. En outre, le procédé est approprié pour des copolymères de tailles et de formes différentes, est facile à utiliser et facile à mettre en oeuvre à l'échelle.
(ZH) 一种聚砜类纳米多孔聚合物的制备方法,包括:将聚砜类聚合物与极性聚合物的共聚物浸没于复合溶胀剂中,在室温以上保持至少1min;所述的复合溶胀剂是由溶剂A和溶剂B混配组成的"溶剂对";所述的溶剂A与聚砜类聚合物有高亲和性;所述的溶剂B与极性聚合物有高亲和性;将处理后的共聚物从复合溶胀剂中取出,干燥脱除溶剂,即得到所述的聚砜类纳米多孔聚合物。该方法得到的聚合物孔道均匀,孔径分布在10-100nm范围内,且相互连通,孔道结构的热、机械稳定性高,孔壁为极性聚合物分子链所覆盖而高度亲水,而且适用于不同尺寸形态的共聚物,操作简便,易于规模化实施。
