1 /. Context:
This internship is part of a research program with various partners in the aeronautics sector, including an equipment manufacturer and university research laboratories. The objective of this program is to improve cabin air quality for both staff and passengers. Mecaprotec is working on the development of an innovative coating to achieve a catalytic coating that will ensure both the conversion of ozone and the elimination of organo-volatile compounds. This deposit will be implemented on aircraft equipment dedicated to air treatment. The objective of the internship is to optimize the process developed at the laboratory scale to comply with both the requirements of the specifications but also the industrial constraints.
Some key words: sol-gel matrix production, catalytic phase impregnation, dip-coating and spin-coating ...
