Ion beam surface modification treatments have been developed to provide the surface of fully isolating  polymer films with surface conductivity in a wide, mostly charge dissipative, range, and environmental durability enhancement, as required for many modern space and terrestrial applications.This paper presents the results of extensive research, containing various ion beams treatment trials. Medium to heavy mass ion beams, from as low as few keV, to moderate, dozens of keV energies have been used. The treatments allowed to decrease the surface resistivity, i.e. develop on the treated polymers a layer with significant surface conductivity, to enhance environmental durability, and provide the polymers with tunable, variable thermal optical properties in a wide range of values. The post-treatment surface conductivity had shown a  comparatively low temperature dependence, that happen to be in a very good agreement for the one characteristic for variable range surface conductivity. Application of various surface characterization methods and modern sophisticated surface analysis techniques have been used for the identification of post-treatment surface conductivity mechanism, as well as durability enhancement mechanisms in terrestrial and space environments. The developed ion-beam surface treatment technologies have been tentatively named Implantox+™ and CARBOSURF+™. All those results have been used for a few options of technology development, followed by successful scale-up trials, some of them in an industrial, manufacturing environment.
