The R&D team at Harvard University hopes to create a perfect coating material that repels liquids and solids, so they seek inspiration from plants. The object of this study is pitcherwood, and those familiar with pitcher plant will know that it will attract ants and spiders, etc., and let these insects fall into traps with their very smooth surface.

Inspired by this, they developed SLIPS materials. This is a self-healing, smooth, liquid-injected, porous surface. Injecting a developed lubricant into a material with nano-microstructures, the repellency cannot be understood literally. What will be the actual effect? We came to their labs to get a glimpse of what happened.

It is able to withstand most liquids, water droplets can easily slip off, oily engine oil is not to mention; they showed us the aluminum panel and glass sheet covering this SLIPS coating, it turns out that as long as the surface is gently lifted, With an inclination, they will slide easily. The biggest challenge comes from the black spray paint, which can even allow the black paint to slip off compared to surfaces without SLIPS. Earlier, this team at Harvard has published related papers. They pointed out that this SLIPS coating material can resist and repel a variety of liquids and solids, and even repel ice and antibacterial; at the same time, if there are some scratches, they can repair themselves. You can also see that SLIPS is like a nepenthes, can slide ants, jump to a video to watch. It should be pointed out that the ant used to demonstrate did not suffer any harm, and of course it was not intentionally slipping.
