INVESTIGATION AND APPLICATION OF EXTREME-PERFORMANCE ELASTOMER NANOCOMPOSITE MATERIALS USING MULTI-WALLED CARBON NANOTUBES.

摘要

Novel and robust elastomeric materials are demanded in various fields such as automobile, water and oil field. Rubber sealants, or O-ring, are key components especially in the probing and production of oil in deeper wells. An oil exploration probe consists of various components, including sensors and a measurment instrument assembled in modules, in which sealants are essential to join adjacent modules. Among present sealant materials, rubbers are widely used in reservoir evaluation as well as in oil production under harsh conditions. They are required an extreme hardness and strength with an appropriate flexibility as well as an excellent structural stability under temperatures and pressures such as 175 °C and 135 MPa, typical conditions in present common wells. [1] In the future, more wells will be drilled deeper, and the oil excavation environment will become much harsher. [2]
