Abstract

Screen printing is introduced to direct the synthesis of crack-free and thickness-tunable TpPa(OH)2 covalent organic framework membranes. A smooth precursor layer is firstly screen printed and then fully crystallised into the TpPa(OH)2 membrane. Molecular-scale pores endow the membrane with a fast water-sieving property, which is promising in water desalination.
