About SLIPS

The SLIPS™ Difference

All solid surfaces, even non-stick or smooth ones, are inherently rough on a microscopic level, creating many points that pin a fluid to the surface and cause it to smear.

 

SLIPS™ surfaces feature a stable, immobilized liquid lubricant over-layer. Unlike solid surfaces, this liquid surface is truly smooth and extremely slippery. Fluids and biological fouling agents have nothing to hold on to and slide right off.

 

SLIPS™ (Slippery Liquid-Infused Porous Surfaces) is based on a portfolio of technologies invented by the Aizenberg Group at Harvard University. These award-winning breakthroughs opened a new field of liquid infused surfaces in materials science that has been adopted by researchers worldwide. The Aizenberg Group was the first to successfully transform the surface of a solid material into a thin, immobilized “sea” of lubricant. This liquid lubricant over-layer completely covers the solid material to create a smooth and slippery liquid surface interface.

SLIPS™ was inspired by the Carnivorous Nepenthes pitcher plant

The plant traps a thin layer of water on the micro-textured surface around its rim. This forms a highly slippery film that it uses to catch insects.

SLIPS™ vs. Alternatives

SLIPS™ provides a 100% liquid interface that is super slippery, omniphobic, self-healing, and easy to clean.

Omniphobic

Self-healing

Easy-clean

In contrast, Teflon® surfaces, although conventionally described as non-stick, are solid surfaces with inherent roughness and are not truly slippery. Structured solid surfaces (superhydrophobic or “lotus leaf” surfaces) are good at repelling water but not other fluids, and they can easily be damaged or lose their hydrophobicity.

SLIPS™ Product Families

We create SLIPS™ surfaces in a variety of ways and on materials including
product-families-1

SLIPS™ formulations are optimized to meet the requirements of specific applications. SLIPS™ coatings and materials can be applied via standard methods such as spraying, painting, and film adhesion and can be created as curable mixtures.

 

Our Surface SLIPS™ products are ideal for applications requiring a thin coating (~50 μm) on any existing surfaces and for the direct modification of metal surfaces.

 

Our Reservoir SLIPS™ products provide longer-term durability and can be used to make casted or extruded parts that have built-in SLIPS™ functionality.

Award-Winning, Globally Acclaimed Technology

SLIPS Technologies has been internationally recognized and highlighted following its first public disclosure by inventor Joanna Aizenberg in June 2011 at the Nanotech Innovation Forum in Boston.

SLIPS received a 2012 R&D 100 Award from R&D Magazine, making it one of the 100 most technologically significant products of the year.
