Description<\/h5>\n\n\n\n
\n

This doctoral thesis aims to develop innovative dopamine-based coatings intended for optical components used in astrophysical applications, building upon the extensive prior research conducted by the Observatory. These coatings are applied via a dip-coating process on conventional optics operating X-rays, enhancing their reflective performance particularly in the soft X-ray band.<\/p>\n\n\n\n

The research will focus on four main areas:<\/p>\n\n\n\n

    \n
  1. Study of growth mechanisms:<\/strong> Using advanced chemical-physical characterization techniques (spectroscopy, microscopy, and X-ray measurements), the mechanisms underlying the polymerization and adhesion of dopamine coatings on optical substrates will be investigated.<\/li>\n\n\n\n
  2. Optimization of recipes:<\/strong> Various formulations and deposition conditions (concentration, temperature, pH, deposition time) will be experimented with to identify combinations yielding optimal optical, mechanical, adhesive properties, and minimal scattering required by astronomical instruments.<\/li>\n\n\n\n
  3. Scattering characterization:<\/strong> Detailed measurements will be conducted to evaluate the scattering caused by these coatings, aiming to minimize undesirable effects and enhance the overall optical performance of instruments.<\/li>\n\n\n\n
  4. Environmental testing:<\/strong> Extensive tests will be performed to assess the resilience of the coatings under simulated space conditions, including thermal vacuum, UV exposure, extreme thermal cycling, and ionizing radiation, to ensure long-term stability and suitability for space missions.<\/li>\n<\/ol>\n\n\n\n

    The research will be conducted at INAF \u2013 Osservatorio Astronomico di Brera, in collaboration with national and international partners involved in the DOVER project (ASI-funded) and previous studies. The ultimate objective is the realization of reliable and high-performance coating prototypes, paving the way for the adoption of this technology in ongoing or future astrophysical missions.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
