Nanoscale Directional Wetting
Researchers at Purdue University have developed a method for controlling ultrathin film structures using sitting phases of polymerizable phospholipids. Such phases are capable of providing nanoscopic directional wetting confinement near the molecular scale for ultrathin films under appropriate deposition conditions or, alternatively, of stabilizing spreading of slightly thicker nanoscopic films. The surface chemistry is compatible with scalable solution-processing methods including spray coating. This method uses monolayers with thicknesses less than 0.5 nm, minimizing electrical resistance in comparison with thicker monolayers. Because the headgroup chemistry is modular, it can be modified to control wetting of a variety of technologically relevant materials including classes of materials relevant to organic optoelectronics or nanoscale electronics.
