Book excerpt: Polymeric materials offer many advantages for low Earth orbit applications including ease of processing and reduced payload-to-orbit costs derived from a reduction in weight. However, over the last two decades it has been well established that polymers used in the construction of space vehicles undergo severe degradation resulting in reduced spacecraft lifetimes. These materials degrade because spacecraft surfaces must endure a high atomic oxygen (AO) flux, bombardment by low and high-energy charged particles, and thermal cycling along with the full spectrum of solar radiation. Many studies have been conducted in an effort to determine the mechanism of degradation primarily caused by surface reactions with oxygen atoms. Unfortunately, these studies have all been carried out after exposing these highly reactive surfaces to air prior to analysis, thus introducing artifacts that do not represent the true effect of the space environment.

This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this research project have been to characterize the degradation of various types of polymers under simulated space (low-earth orbit (LEO)) conditions and to develop polymers for spacecraft coatings which have improved survivability in LEO. Many polymers have been tested including kapton, polyethylene, fluoromers, polyhedral oligomeric silsequioxane (POSS)-containing copolymers and others. The testing was performed in an ultrahigh vacuum system which contained an atomic oxygen (AO) source and a vacuum ultraviolet (vuv) source. In some studies the polymers were also exposed to energetic electrons and ions. The chemical alterations occurring during the degradation was monitored using X-ray photoelectron spectroscopy (XPS). All polymers exhibit large chemical changes. The POSS-containing polymers are particularly interesting for space applications because they form a thin silica layer which protects the underlying polymer from further degradation.

This book was released on 2009-01-15 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conference proceedings are discussing the latest developments in the area of the effects of the space environment on materials and structures and the ways to prevent and/or reduce them. The effects of various space environment factors like atomic oxygen, vacuum ultraviolet radiation, charging, micrometeoroids, meteoroid showers, etc. on materials and structures in various space conditions are discussed. In addition the ways to prevent these effects or reduce them through protection by coatings or modification of affected surfaces are considered in the book. The discussions on development of predictive models of material erosion that will allow the materials engineers and designers of future spacecraft to evaluate materials' behavior is continued from the past meetings.

This book was released on 1999 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The surface of a film of a polyhedral oligomeric silsesquioxane (POSS)-siloxane copolymer has been characterized in-situ using X-ray photoelectron spectroscopy (XPS) before and after exposure to incremental fluences of oxygen atoms produced by a novel hyperthermal oxygen atom source. The data indicate that the atomic oxygen initially attacks the cyclohexyl groups that surround the POSS cage resulting in the formation and desorption of CO(2) from the surface.
