Preparation of hydrophilic PMMA/β-CD nanofibers and its adsorption properties of Cu~(2+)

For the purpose of developing a molecular membrane or new nanofiltration membrane materials to capture the heavy metal ion in waste water treatment and organic small molecule pollutant,electrostatic spinning technique was used to prepare PMMA /β-CD composite nanofibers.The wettability,antistatic and adsorption to Cu2 +were studied.The results showed that when the β-CD quality percentage in composite nanofibers increases,the wettability of composite nanofibers increases,and when the mass percentage of β-CD is 30%,the wettability of composite nanofibers increases significantly.With the increase of β-CD content in composite nanofibers membrane,its half-life is reduced,indicating significant antistatic effect.The adsorption capacity for heavy metal Cu2 +increases with the increase of the content of β-CD.
