Pis prepared with 4,4 -oxydianiline (ODA) and 3,3, 4,4 -benzo-phenone tetracarboxyhc dianhydride (BTDA) monomers, cf. Figure 6.1, can be loaded with 10 and 15 wt% tungsten nanoparticles that are treated with benzyl mercaptan. The 3,3, 4,4 -benzophenone tetra-carboxylic dianhydride and ODA monomers are reacted to form PI films that are flexible to the point of being creaseable. The nanocomposite films are effective as an electromagnetic radiation shield (5).

The idea of using CPCM for shielding is rather alluring. Indeed, a casing of an article or instrument manufactured of such a material serves at the same time as a screen to protect against electromagnetic radiation. All the above-described operations involved in applying additional layers become unnecessary.

Every electronic system has some level of electromagnetic radiation associated with it. If this level is strong enough to cause other equipment to malfunction, the radiating device will be considered a noise source and usually be subjected to shielding regula-... 

Ozone absorbs ultraviolet radiation below 320 nm. It thus forms an indispensable shield in the upper atmosphere, protecting the Earth s surface from most of the potentially hazardous effects of such high-energy electromagnetic radiation. There is now increasing concern because atmospheric pollutants are depleting the ozone layer worldwide, with the most serious depletion over Antarctica as a result of seasonal variations in high-altitude air circulation. In the upper atmosphere, ozone is formed from O2 ...

Because ozone selectively absorbs these deleterious wavelengths of solar radiation, it serves as an ultraviolet shield. As such, stratospheric ozone helps to protect humans and other organisms on Earth s surface from some of the harmful effects of exposure to this high-energy electromagnetic radiation, hi fact, without the protective action of the stratospheric ozone layer, it is likely that...
