Description
In recent years, there has been growing interest in the development of sustainable products, technologies and processes. Furthermore, the new and more restrictive environmental normative and policies are devoted to the gradual substitution of the current materials and processes for environmentally clean ones that will allow a sustainable use of the environmental resources. The main objective of the project MSM is the implementation of environmentally clean processes for the functionalization of inorganic micropigments through the use of low energy plasma techniques. The development of this kind of processes will represent an alternative to the widely used wet-functionalization techniques, avoiding the use of solvents and the production of residues. Specifically, in this project plasma surface modification will be used to improve the stability of the pigments as well as to the development of UV protection coatings in different inorganic micropigments. The optimization and adaptation of this technique to its use in the ceramic sector will allow the development of sustainable novel inorganic pigments with high added value.
Summary of project results
During the development of this project have been synthesized different pigments based mixed oxide with different chemical compositions and morphologies: specific black copper-chromium titanate, chromium, cobalt aluminate, and various types of zinc ferrite, some of them with high surface . These pigments have subsequently been used for surface modification processes using PA-CVD. MMS project has evaluated the potential of PA-CVD technique as environmentally clean a surface modification processes wet alternative. Thus, processes have been developed different surface modification of pigments micron size by this plasma assisted technique. It has been found that the pigment surface activation by plasma processes can positively modify the dispersion and color strength.
