Electrostatic Self Assembly
Industrial scale “Layer-by-layer”
- Waterborne process, very low energy consumption
- No vacuum or high temperature baking is required
- Relies on the attraction between two complementary molecules to build up a film one layer at a time
- Typically, this is a positively charged polymer and a negatively charged polymer or nanoparticle
- Incrementally build to the desired thickness, and add multi-functionality by stacking films and layers
- We can even transfer that functional film to another substrate with downstream processing on site
Ion exchange and particle loading
- Similar to the 3-D beads in deionizing resin beds, but customized for 2-D high surface area coatings
- The product is the bead surface, but in sheet form
- Load blends of ions into a functional coating via ion-exchange
- Optionally grow catalytic nanoparticles of specific size and shape
- Ideal for turning a passive coating into an active thin film with customized functionality
Gravure coating
- Ideal for coating 5-100 microns of solid from a solution in water or a small amount of cosolvent
- Wet film thickness is metered by the volume contained within small pits on the surface of a gravure roller
- We can refine that thickness using metering rods with higher precision than a gravure roller alone
- Prior to drying the bumps settle into a smooth layer
- Solvent is then removed by convective dryer to leave a dry film of prescribed thickness and moisture content
