Self-repairing cement polymer composites and processes of making and using same

Title: Self-repairing cement polymer composites and processes of making and using same

Abstract

New cement-polymer composites and processes of making and using are detailed. One exemplary cement-polymer composite include a Portland cement, an epoxide polymer, a thiol-containing crosslinking agent, and an optional phase separation inhibitor. These composites are dynamically self-healing, mechanically robust, and thermally stable in high temperature environments and can be expected to increase service lifetimes in various applications including energy producing wellbores.

Composites comprising novel RTIL-based polymers, and methods of making and using same

Patent Gin, Douglas; Carlisle, Trevor; Noble, Richard; ...

The invention includes compositions comprising curable imidazolium-functionalized poly(room-temperature ionic liquid) copolymers and homopolymers. The invention further includes methods of preparing and using the compositions of the invention. The invention further includes novel methods of preparing thin, supported, room-temperature ionic liquid-containing polymeric films on a porous support. In certain embodiments, the methods of the invention avoid the use of a gutter layer, which greatly reduces the overall gas permeance and selectivity of the composite membrane. In other embodiments, the films of the invention have increased gas selectivity and permeance over films prepared using methods described in the prior art.

High-pressure, high-temperature magic angle spinning nuclear magnetic resonance devices and processes for making and using same

Patent Hu, Jian Zhi; Hu, Mary Y.; Townsend, Mark R.; ...

Re-usable ceramic magic angle spinning (MAS) NMR rotors constructed of high-mechanic strength ceramics are detailed that include a sample compartment that maintains high pressures up to at least about 200 atmospheres (atm) and high temperatures up to about least about 300.degree. C. during operation. The rotor designs minimize pressure losses stemming from penetration over an extended period of time. The present invention makes possible a variety of in-situ high pressure, high temperature MAS NMR experiments not previously achieved in the prior art.

Paintable hydrophobic and lubricant-infused surface coatings and processes for making and using same

Patent Addleman, Raymond S.; Larimer, Curtis J.; Barrett, Christopher A.; ...

Compositions and processes are disclosed for forming hydrophobic coatings and lubricant-infused surface coatings. Coatings may be applied to various substrates without prior chemical or temperature treatment of the substrates and over large and irregular surfaces. Coatings are self-healing, anti-fouling, and have enhanced lifetimes.
