Fabrication of a self-standing supramolecular membrane by a “soft spray” technique

Abstract

We report a one-step method to fabricate a free-standing supramolecular membrane composed of melamine and barbituric acid coordinated with silver nitrate (Mba–Ag) at the gas/liquid interface by a soft spray technique. MBa–Ag exhibits a folded two-dimensional layered morphology and thickness of 4.5 μm. The shortwave IR transmittance of MBa–Ag is as high as 95%, which is much higher than the transmittance of UV and visible light, and has the potential for electromagnetic wave transmission.
