Our versatile method reacts gaseous precursors on a surface to make it anything from superhydrophobic to superhydrophilic. By operating under atmospheric conditions and selecting the most cost-optimized region of the reaction spectrum, we offer the most affordable solution for obtaining a long lasting effect without having to reapply the coating.

Value Proposition: Current hydrophobic/hydrophilic surface treatments include on one hand high performance sophisticated techniques such as plasma-enhanced chemical vapor deposition (PECVD) that is used in the electronics industry for example. For most applications, these approaches are unfortunately too costly since they require high vacuum conditions and controlled temperature which necessitate specialized equipment. On the other hand, there exist a number of lower cost methods that involve some kind of dipping, spin coating or spray coating. These techniques however usually result in nonuniform wetting properties due to varying layer thickness and quality such that the coating has to be reapplied over time if we want to preserve the effect. Moreover, due to weak bonding, the coatings are instable over time. What we are proposing is an intermediate solution that produces durable uniform coatings while being much cheaper than PECVD since our technology uses a low-cost UVC source and can be performed under atmospheric conditions. Another advantage is that the method can work on parts of any shape and not only on flat surfaces. It is perfect for added-value products that require high performance but yet need a method that remains easy to implement in an industrial setting.
