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.

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