Functionalized Boron Nitride Membranes with Multipurpose and Super-Stable Semi-permeability in Solvents

Abstract

Multipurpose and super-stable molecular sieving membranes exhibit great potential to realize mixture separation at low energy cost within extreme chemical and thermal environments. However, nano-porous membranes are currently only used in a relatively limited range of solvents. These membranes, when used in some solvents are easily degraded at high temperatures or in harsh chemical environments. Here, we report on an ultrathin functionalized boron nitride (FBN) membranes that will provide unprecedented multipurpose molecular separation. The FBN membranes show high permeation and selectivity in aqueous and organic solutions. The FBN membranes also maintain super-stable sieving performance even after exposure to high temperatures of up to 200 ℃ for 1 hour. The FBN membranes are stable in a range of solvents (water, ethanol, acetone, toluene, and hexane) for up to 24 hours, as well as in extreme pH conditions (0.5 mol/L NaOH, 0.5 mol/L H2SO4, 0.5 mol/L HNO3) for 24 hours, respectively. These multipurpose, super-stable FBN molecular-sieving membranes, can potentially be used within a range of high throughput manufacturing processes to facilitate large scale molecular separation to meet the demands of many industrial requirements.
