Abstract: Tests of some space materials on resistivity against atomicoxygen were carried out by using our radio frenquency oxygen plasmareactor.These materials involves aluminized kapton,polytetrafluoroethylene,polyester film,polyimide,silastic,carbon/epoxy composite,kevlar,as well asAg,Cu,Al foid and optical solar reflector.Mass loss rate,surfacespecific resistance,solar absorptivity(α_s)and infrared radiance(ε)afteroxygen plasma exposure were measured.Furthermore,experimental resultsand feasibility were discussed.
