Resist materials organic-inorganic composites

Reinforced polymers with inorganic fillers are known to show greater resistance to radiation than original polymers. Most of organic materials in fusion reactors must be designed to employ organic-matrix composites as it appears very doubtful that conventional polymers can withstand the severe radiation environment for a reasonably long operation time. 

The most important methods for preventing atmospheric corrosion are 1) to select a corrosion-resistant structural material, 2) to use a corrosion-resistant coating (metallic, inorganic, organic or composite), and 3) to close internal cavities in order to avoid access of humid air, or conversely, 4) to make sure that there is ample ventilation and drainage, and possibly 5) to supply oil, grease, or special substances such as tectyle to the cavities. 

In recent years, the combination of polymers and inorganic materials to polymer composites comes to steadily growing interest. Synergetic aspects such as chemical resistance or elasticity of the organic compounds and hardness, stability or interesting electrical and optical properties of the inorganic compounds offer an immense potential for new materials or applications. Hofman-Caris presented a detailed review about particle formation procedures as well as chemical coupling procedures that form core shell structures prior to 1994. ... 

Recentiy, a new class of organic-inorganic hybrid materials based on the ultra incorporation of nano-sized fillers (nanofillers) into a polymer matrix has been investigated. Nanotechnology is the aptitude to work on a scale of about 1-100 nm in order to understand, create, characterize and use material structure, devices, and system with unique properties derived from their base on the nanostructures. Nanocomposites could exhibit exclusive modifications in their properties, compared with conventional composites in terms of physical properties, including gas barrier, flammability resistance, thermal and environmental stability, solvent uptake, and rate of biodegradability of biodegradable (Chivrac et al. 2009).
