TresClean Achievements 

At the end of a very intense research period the TresClean project has successfully completed its mission to demonstrate that tailored surfaces replicating the types of organic structures found in nature can produce beyond state-of-the-art fluid-repellent and antibacterial surfaces. In doing so the project has brought laser texturing out of the lab and contributed to tailored photonics solutions in a very innovative field. 

Specific achievements of the project include: 

  • Identification of ultrashort pulsed laser texturing as a suitable technique for producing antibacterial surfaces

  • Application of laser texturing to generate different topographies, characterized by feature size ranging from a few hundreds of nm to tens of µm

  • Identification of suitable surface topographies to reach super-hydrophobic and antibacterial effects.

  • Development of a high power laser delivering 1kW of output power and >3mJ of pulse energy, including the demonstration of high-power visible (green) and UV radiations with more than 600W and 200W power respectively.   

  • Development of a scanning system with processing speeds of up to several hundred m/s, improved resolution and sufficient accuracy to support laser power up to 1kW.

  • Upscaling of the TresClean laser texturing technique to produce structures with a laser repetition rate of 10 MHz, at a scanning speed of 200 m/s in a field size of 200x200 mm.

  • Transfer of nanoscale topographies on polymers by injection molding.

  • Generation of functionalised surfaces on free-form components such as metal pipes.
