界面聚合法制备PEO中空纳米微球及其对气体渗透性的影响
Synthesis of hollow PEO microspheres via interfacial polymerization and their effects on gas permeation performance
摘要
Abstract
In order to obtain high penetration and selection performance, hollow polymer microspheres were prepared by polymerization of polyethylene glycol methyl ether acrylate and dipentaerythritol hexaacrylate at the oil-water interface of surfactant-free microemulsion using the interfacial initiator. The membranes with nanocavities were formed by casting the hollow microspheres microemulsion and the effects of the nanocavities on the gas permeability and selectivity of the separation membrane was investigated. The results showed that the resulting hollow microspheres have an average size of 95 nm, and a hollow structure. At high concentration of crosslinking agent, the permeability of membranes with nanocavities increased significantly compared with the intrinsic permeability of shell material. At 35 ℃, 0.2 MPa, the permeability coefficient of CO2 of the hollow microspheres membranes increased by 4.5 times and the separation coefficient also improved.关键词
