Novel Ink Formulation for Uniform Films of Particles

Summary

Researchers at Purdue University have developed a technique that makes uniform thin films with monolayer capability through evaporation. Using concepts of vapor pressure and diffusion, the resulting deposit of metal particles after evaporation is uniform with a surface roughness as small as that of closely packed particles. This novel technique uses metal particles and solvents. This process works under standard temperature and pressure (STP) and it does not require a transfer process that is used in current techniques. It can be integrated into inkjet systems.
