About SLIPS

Across industries, removing contaminants, residues, and biofilms from various types of surfaces found in manufacturing equipment or maritime shipping vessels costs money and time. SLIPS™ cutting-edge coatings work by transforming surfaces into a slippery, self-healing liquid layer—making sticky materials slide right off.

 

SLIPS™ can be applied to a wide range of materials, including plastics, metals, ceramics, glass, and even concrete. SLIPS™ repels all kinds of liquids and products: motor oil, paint, aqueous emulsions, and consumer products like lotions and gels, as well as blood, bacteria, insects, and marine organisms.

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, fully 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 lubricant layer.

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

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 existing 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.
