Space Radiation Resistant Transparent Polymeric Materials.
Abstract
A literature search in the field of ultraviolet and charged particle irradiation of polymers has been utilized in an experimental program aimed at the development of radiation stable materials for space applications. This report describes the rationale utilized for material selection and the synthesis, characterization and testing performed on several selected materials. Among the materials tested for ultraviolet stability in vacuum, polyethyleneoxide, polyvinylnaphthalene, and the amino resin synthesized by the condensation of o-hydroxybenzoguanamine with formaldehyde have shown promising properties. Particularly interesting, and unexpected, was the radiation behavior of poly(ethyleneoxide), in that irradiation did not cause degradation of optical properties but rather an improvement in transparency as indicated by a decrease in solar absorptance with increasing exposure time. A summary of a literature search in the field of radiation effects and a review of preliminary irradiation tests performed under previous contracts No. NASl-l2549 and No. NAS1-13292 (July 1973 through September 1975) are included for reference.
