Накратко на български

Повърхности, напоени с масло, се изследват за предотвратяване на замърсяване и образуване на лед. Те помагат за създаването на материали, от които бактериите и течностите се плъзгат лесно, което подобрява хигиената и индустриалната ефективност.

Lubricant impregnated slippery surfaces

The LubISS project aims to explore the expansive potential of lubricant impregnated surfaces, focusing on three applications of high societal, environmental, industrial and medical impact: Anti-icing, easy-to-clean and anti-fouling. Textured substrates, which are infiltrated with a lubricant form a new class of functional surfaces, referred to as Lubricant Impregnated Slippery Surfaces (LubISS). The mobility of particular matter on lubricated surfaces greatly reduces the (lateral) adhesion. Therefore, deposited liquids, bacteria or other microorganisms can slide off easily as soon as the surface is tilted by a few degrees. Although capillary forces help to keep the lubricant in place, LubISS face the problem of limited durability. The lubricant needs to be replenished after some time. The LubISS network has tacked these challenges. For long-term applications of lubricant impregnated surfaces, small interstices are essential, preferentially below 50 nm. This can be achieved by impregnating densely packed nanoparticles with a non-volatile oil. The ice adhesion strength remained very low, even after 50 icing and deicing cycles on the same spot. Lubricant depletion can also be prevented using active methods. The formation of a shear-resistant lubricant film was achieved by flow-induced self-lubrication using an emulsion. The LubISS network also contributed to a greatly improved understanding of the interactions between lubricant-drop-substrate-air. A generic description of the dependence of the friction force on velocity, interfacial tensions, viscosity of the drop and lubricant was derived. This insight is essential to design easy-to-clean surfaces. We quantitatively, described the shape and temporal evolution of the lubricant underneath an impacting droplet, a si tuation encountered in spray coating or ink-jet printing. LubISS provided the early stage researchers (ESR) with excellent cross-disciplinary education. It proved very useful to enhance their management, communication and mentorship skills required to become future leaders in academics or industry.

Цел на проекта

LubISS, Lubricant Impregnated Slippery Surfaces, is the first European Training Network with the main objectives of designing, characterizing, and modelling low adhesive easy-to-clean surfaces for anti-icing and anti-fouling. In a coordinated effort among 9 world-class academic institutions and industrial partners from 6 European countries (Finland, France, Germany, Great Britain, Netherlands, Switzerland), advanced lubricant impregnated surfaces will be developed. Drawing upon the distinguished expertise within the consortium, textured surfaces impregnated with a lubricating liquid or gel will be designed and fabricated through modern experimental preparation, multi-scale characterization methods, and high power simulation tools. With these broad capabilities, the LubISS network offers a unique training platform for Early Stage Researchers (ESRs) in a multidisciplinary research endeavor of great technological, industrial and environmental importance. The recently introduced concept of lubricant impregnated surfaces is a promising approach to reduce the adhesion of ice as well as biofilm-forming bacteria-to-surfaces. To achieve societal impact, understanding the intimate relationships between the impregnating lubricant, the surface topography, and the adhesion of ice, bacteria, or other biofouling microorganisms is critical. The general aim of this ITN is two-fold: 1) to establish a fundamental understanding between these relationships through academic and industrial collaborations in physics, chemistry, biomedicine, materials science and engineering, and 2) to educate and train young researchers in this vital area of technology. The LubISS network will investigate many aspects of lubricant impregnated surfaces, including the optimization of the lubricant stability under static and dynamic flow conditions, methods for replenishing the lubricant for long-term applications, and benchmarking against state-of-the-art surfaces.
