dc.description.abstractEnStudy of interactions between charged particles and materials is of prime importance in the aerospace industry. Indeed, these energetic particles can induce damages to any spacecraft whether it be on the external parts of it or on its on board electronics. Silicon resins are materials that play an important role on those devices due to their unique properties. When exposed to proton irradiation, such resins tend to crack and turn yellow. This is detrimental to the proper ageing of the resins, which lose their original properties with time. One of the considered solution for stabilizing such a material is the introduction of charges in the matrix. This paper focuses on the synthesis of a class-I hybrid material where the proton facing side of a polydimethylsiloxane (PDMS) resin is filled with silica nanoparticles in order to limit its premature degradation. Resins bearing silica particles ranging from 230 nm to 2 μm diameter with total nanoparticles thickness ranging from 1 to 28 μm were synthetized. The obtained materials were irradiated with 240 keV protons to simulate their ageing and were characterized by UV-Vis-NIR spectroscopy as well as optical and scanning electron microscopy.
