Abstract: The present invention comprises an automated apparatus capable of spray depositing polyelectrolytes via the LbL mechanism with minimal or no human interaction. In certain embodiments, the apparatus sprays atomized polyelectrolytes onto a vertically oriented substrate. To counteract the effects of irregular spray patterns, the substrate is preferably slowly rotated about a central axis. In certain embodiments, the apparatus also includes a forced pathway for the droplets, such as a pathway created by using a vacuum. In this way, a thicker or three-dimensional substrate can be coated. In certain embodiments, the apparatus is designed so as to be scalable. Thus, through the use of multiple instantiations of the apparatus, a large or irregularly shaped substrate can be coated. Rolls of textile can therefore be coated using the apparatus. Additionally, the present invention includes a method to uniformly coat a substrate, such as a hydrophobic textile material, using aqueous solutions of polyelectrolytes.

Abstract: An elastomeric stamp is used to deposit material on a non-planar substrate. A vacuum mold is used to deform the elastomeric stamp and pressure is applied to transfer material from the stamp to the substrate. By decreasing the vacuum applied by the vacuum mold, the elasticity of the stamp may be used to apply this pressure. Pressure also may be applied by applying a force to the substrate and/or the stamp. The use of an elastomeric stamp allows for patterned layers to be deposited on a non-planar substrate with reduced chance of damage to the patterned layer.
