Fabrication of BN membranes containing high density of cylindrical pores using an elegant approach

Abstract

A high quality BN membrane with millions of through cylindrical pores is simply fabricated using a double inversion approach combining atomic layer deposition and polymer-derived ceramic route. Well crystallized hexagonal boron nitride walls are obtained at relatively low temperature (1000 °C). This new membrane is a promising candidate for osmotic energy conversion and water filtration applications.
