  Organic Pollutants in the Built Environment and Their Effect on the Microorganisms (C Saiz-Jimenez) Air Pollution Damage to Metals (J Tidblad & V Kucera) The Effect of Air Pollution on Glass (J Leissner) The Effects of Ozone on Materials — Experimental Evaluation of the Susceptibility of Polymeric Materials to Ozone (D S Lee et al.). Callisters Materials Science and Engineering: An Introduction, 10th Edition promotes student understanding of the three primary types of materials (metals, ceramics, and polymers) and composites, as well as the relationships that exist between the structural elements of materials and their properties.

Environment Structures Guidance and Con trol Polymeric substances, however, are considerably more sensitive to radiation and significant effects are to be expected. In the case of all three categories of materials (metals, ceramics, and polymers), nuclear-reactor and radioisotope-power radiations are Nuclear and Space Radiation Effects File Size: 1MB.   Prediction of In-Space Durability of Protected Polymers Based on Ground Laboratory Thermal Energy Atomic Oxygen The probability of atomic oxygen reacting with polymeric materials is orders of magnitude lower at thermal energies (impact energies ( eV).

Polymers constitute an extremely large class of materials generally based on carbon chemistry. Their long chain structures and unique molecular architecture make them distinct from metals and ceramics and provided them with a very wide range of by: The book begins with an introduction to geomembrane polymeric materials and their properties and manufacturing. Further discussions describe the different types of materials such as High-Density Polyethylene (HDPE) as well as their properties, shortcomings and applications. Geomembrane survivability such as chemical exposure effects are also.

Space research demands very stringent requirements from these polymers because of the extreme environments experienced by these materials 1. The polymers used outside the space system are the most affected ones. As we move from space exploration to space commercialization, these polymers have to last for 15–20 years of their designed by: 2.

Space environmental effects on polymeric materials. Two of the major environmental hazards in the Geosynchronous Earth Orbit (GEO) are energetic charged particles and ultraviolet radiation. The charged particles, electrons and protons, range in energy from to 4 MeV and each have a flux of 10 to the 8th sq cm/sec.

The effects of 5 years and 9 months of low-Earth orbit (LEO) exposure of these materials to atomic oxygen (AO), ultraviolet and particulate radiation, meteorid and debris, vacuum, contamination, and thermal cycling is providing a data base unparalleled in the history of space environment research.

National Aeronautics and Space Administration.]. The effects of radiation on polymer materials is an area of rapidly increasing interest.

Several high technology industries require specialty polymers that exhibit a specific response upon exposure to radiation. For instance, the electronics industry requires materials that undergo radiation induced scission or crosslinking for resist applications, while aerospace and medical.

Understanding the behavior of polymeric materials when exposed to the low-Earth-orbit (LEO) environment is important in predicting performance characteristics such as in-space durability. Atomic oxygen (AO) present in LEO is known to be the principle agent in causing undercutting erosion of SiOx protected polyimide Kapton® H film, which serves.

polymeric materials with improved resistance to the vacuum-radiation environment of space and potentially useful in space applications such as second surface mirrors, solar cell adhesives and protective coatings.

The problem of polymer stability to a combined ultraviolet/ high-energy radiation environment stems from the opposite.

This book discusses the effects of radiation in polymers and their structure as well as its impact on the polymers' properties. It introduces the synthesis, characterization, or modification of many important materials, e.g. polycarbonates, polyamides and polysaccharides, using radiation.

As environmental performance becomes increasingly important, the development of man-made polymers and their associated benefits has been overshadowed by problems relating to their ultimate disposal.

In the light of wider acceptance of polymers for use in high technology applications, Polymers and the Environment aims to redress the balance. The book reviews Cited by:. The conversion efficiency is directly related to the transmissivity of the polymeric lens.
