  • Patent number: 10875810
    Abstract: Examples of novel self-repairing cement-polymer composites and processes of making and using are detailed that address various problems in prior art cements. These matrices, compositions and materials that are more mechanically robust, thermally stable and chemically resistant and demonstrate better bonding to various structures and materials, than other self-healing cements known in the prior art. When in place under preselected conditions (the formulation of the slurry can be modified for optimal effectiveness under various conditions) the organic, cross linking and cement forming portions within the slurry form interconnecting chemical bonds and cures to form a self-repairing and self-re-adhering cement polymer composite matrix in the receiving location.
    Type: Grant
    Filed: June 17, 2019
    Date of Patent: December 29, 2020
    Assignee: BATTELLE MEMORIAL INSTITUTE
    Inventors: Carlos A. Fernandez, Phillip K. Koech, Wooyong Um, Vassiliki-Alexandra Glezakou, Jaehun Chun, M. Ian Childers, Manh Thuong Nguyen, Kenton A. Rod

  • Patent number: 10370577
    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.
