While many surface modification treatments can repel water-based liquids, very few can repel oil-based liquids. Materials that can repel oil-based liquids currently require environmentally unsustainable chemistries such as fluorocarbons. Many of these surface modification treatments do not resist simple abrasion, even a simple touch with your finger. Furthermore, many approaches for creating liquid-repelling surfaces also negatively impact the aesthetics of the treated item.
A consumer goods company is seeking novel self-cleaning / liquid repelling technologies, especially alternate surface modification technologies that controls the wetting, spreading and adhesion of water and oil-based soils. An environmentally safe, durable and surface friendly solution is sought.
Key requirements for the technologies are as follows:
