Hyperbranched grafting enabling simultaneous enhancement of the boric acid uptake and the adsorption rate of a complexing membrane

Abstract

Hyperbranched polyols were grafted onto a PAN membrane <italic>via</italic> a two-step process for boron removal. The grafted hyperbranched scaffold was utilized to optimize the ligand distribution so that a complexing membrane with both high capacity and high adsorption rate was obtained.
