Preparation and characterization of space durable polymer nanocomposite films

Low color, flexible, space durable polyimide films with inherent, robust electrical conductivity have been under investigation as part of a continuing materials development activity for future NASA space missions involving Gossamer structures. Electrical conductivity is needed in these films to mitigate electrostatic charge build-up caused by charged species present in the orbital environment. One method of imparting conductivity is through the use of single-walled carbon nanotubes (SWNTs). SWNTs were dispersed in space durable polyimide films in the bulk using a solution technique and on the surface using a spray coating technique. The resultant nanocomposite films were evaluated for electrical conductivity, mechanical, and optical properties. The results of this study will be presented. (c) 2004 Elsevier Ltd.
