Multifunctional High Performance Perfluoropolymer Nanocomposite Seals
Extending the duration of drilling operations without interruption is important to increasing the productivity and lowering the cost of geothermal drilling. However, the polymer and metal seals in current use are unable to sustain temperatures greater than 200 C and pressures of several thousands psi. New materials are required to address these emerging challenges. This project will develop a new class of perfluoropolymer-based nanocomposites ¿ in which different nanomaterial additives will be used to provide multiple functionalities, thereby enhancing a multitude of properties simultaneously. These properties include wear resistance, compression set, high temperature resistance, and reduced gas and liquid permeability. In Phase I, a variety of nanomaterial additives, all compatible with the base polymer, will be synthesized. Then, polymer nanocomposite samples, with significantly higher cross-linking density than the base polymer, will be fabricated. The mechanical properties, thermal stability, and permeability of the nanocomposite samples will be measured and compared to properties of the base polymer. Commercial Applications and other Benefits as described by the awardee: The creation of uniquely fluoromodified nanoadditives for sealing applications should provide a new set of performance characteristics for highly fluorinated materials. In addition to oil, gas, and geothermal drilling operations, processes in pharmaceuticals, medical devices, and microelectronics could benefit from seals that offer better barrier and mechanical performance. The technology also would facilitate a greater degree of safety for workers involved in these industries.
