Abstract
In an effort to introduce low levels of electrical conductivity into space durable polyimides while maintaining optical clarity, nanocomposites containing metal oxides were prepared and characterized. Polymeric materials that exhibit space environmental durability, high optical transmission, low solar absorptivity and sufficient electrical conductivity for electrostatic charge dissipation are needed for future ultra-lightweight, deployable spacecraft. Samples were prepared by the addition of the metal oxide to a pre-made polyimide solution and by the synthesis of the polyimide in the presence of the metal oxide. Sonication was used to aid in the dispersion of the metal oxide particles in N,N-dimethylacetamide prior to mixing. Thin films were prepared and characterized for thermal and mechanical properties, solar absorptivity, thermal emissivity, electrical conductivity, optical transmission and degree of dispersion of the metal oxide particles. The effect of the metal oxide particles on the polyimide properties will be discussed.
