  3. CONCEPT GREENER Improve, develop and implement sustainable and environmentally friendly nanopigments, based on nanoclays and colorants (natural, thermochromic, photochromic, electroluminiscence)

  4. PARTICIPANTS GREENER

  5. TECHNICAL OBJECTIVES GREENER Create technologies enabling the production of nano-pigments: Environmentally friendly ways Sustainable raw materials Objectives • Preparation of nano-pigments based on nano-clays and dyes (natural or synthetic) • Surface treatment technologies for nano-clays to improved dye fixation • Surface treatment technologies for nano-pigments to improve light-fastness, weather-resistance, fatigue cycle and dispersibility. • Applicability of the GREENER nano-pigments in printing inks, paints and coatings. • Applicability of the GREENER nano-pigments in photovoltaic devices. • Evaluation of the environmental impacts of the GREENER nano-pigments. • Commercial exploitation and dissemination of GREENER nano-pigments

  6. PROGRESS BEYOND THE STATE-OF-THE-ARTGREENER Current State-of-the-art Progress State-of-the-art Nano-pigments based on natural dyes Wide colour gammut Functionalised nanopigments (photochromic, thermochromic, electrochromic) Surface treatment technologies for nanopigments Environmental impacts of nanopigments and nanoclays Application of nanopigments in photovoltaic devices, inks, paints, coatings. • Nanopigment (Planocolors®): good carrier for dyes • Challenges: • Strong bonding • Lower stability compared to organic pigments • Lack of special functionalization • Lack of industrial application • Few reports about environmental impacts • Not research in photovoltaic devices

  7. IMPACT GREENER • Strategic impact • Improve technologies • Application of nanotechnologies • Strengthening EU’s leading position implementing nanotechnologies • Enhancement of environmental sustainability of manufacturing process • Promote markets for “green nanotechnology” • Replace hazardous substances and reduce non-eco waste material.

  8. CONCLUSION GREENER Challenging cooperative work Great variety of fields and industrial applications: textile, polymers, printing inks, etc. Improvement of life quality Highly competitive environmentally friendly European industry Enhance and boost European institutions in nanoscience and nanotechnology
