FTA Project

Functional Coatings and Printed Devices

 

The use of modern nano-materials has grown considerably in recent years. These products are revolutionizing the use of electronic displays, enabling medical and industrial coatings, paving the way to personalized medicine and have a wide range of agricultural uses. Researchers are using nano-particles to create smarter materials. At the Hebrew University Center for Nanoscience and Nanotechnology (HUCNN), FTA groundbreaking research is ongoing in two main fields of industrial application ; functional coatings and printed devices.

 

1. Functional coatings: Smart paints with self-assembly properties for application on different surfaces offering functionality beyond color, such as light spectrum converters for home and greenhouses, thermo-solar paints for high temperatures, antibacterial and anti-fouling coatings for walls and food packaging, impact resistant reflective coating for mirrors and anti-corrosion coatings.

 
                                                                                                            

Strong Biodegradable Sheets from Renewable Resources

Oded Shoseyov (TL), Yossi Paltiel, Daniel Mandler, Itamar Willner & Uri Raviv.

In this sub-project we present novel biodegradable strong coatings with tunable light adsorption spectrum that can be used in agriculture to make more efficient greenhouses and for the food packaging industries for food preservation.

 
 

Thermosolar Coatings Based on Hybrid Nanostructures,

Daniel Mandler (TL) & Shlomo Magdassi

      In this sub-project we focus on forming new black absorbers for light harvesting by solar thermal devices. The coatings are composed of ceramic materials and nanomaterials and exhibit excellent absorption with very good thermal stability.

 

Hybrid Nano-systems for Antibiofouling, Antirusting and Antimicrobial Coatings,

     David Avnir (TL), Meital Reches, Daniel Mandler, Oded Shoseyov & Uri Raviv

In this sub-project we present new materials with antifouling and antibacterial properties. The antifouling materials prevent the attachment of organisms to surfaces. We are planning to develop the new material into a multi-functional green sprayable coating, which can be used in hospitals and in the marine industry.

 

 

2. Printed devices: Materials and inks for electronic and optical devices printed on paper and plastics offering low cost flexible products such as RFID tags, fluorescent signage, electrodes for plastic solar cells and printed transistors.
                                                                                                             

A new technology for synthesis and sintering metallic and semiconductor NPs at low temperatures for electronic and opto-electronic applications

Shlomo Magdassi (TL), Uri Banin, Oded Millo & Danny Porath. In this sub-project we develop new processes for the sintering of nanoparticles and new metallic inks that are suitable for applications at low temperatures in printed electronics, which means that various heat sensitive optoelectronic devices can be fabricated, such as plastic displays, solar cells and touch screens.

 
 
 
Fluorescent semiconductor NC inks for signage and display applications

Uri Banin (TL) and Shlomo Magdassi

In this sub-project we develop new inks composed of nanocrystals that can provide unique optical     properties after printing. In particular, size dependent control over the fluorescent color can be used to achieve new type of fluorescent inks for diverse applications in lighting, displays, signage and more.

 

 

Transparent Flexible Electrodes and Light Sensors

Shlomo Magdassi (TL), Yossi Paltiel, Shlomo Yitzchaik, Yael Hanein, Danny Porath, Uri Banin, Lioz Etgar & Oded Shoseyov

This project develops transparent conductors composed of organic materials, for optoelectronic applications, and new low cost flexible light sensors composed of printed nanomaterials for use in devices such as plastic electroluminescent lighting, remote touch screens and solar cells.
