  • Publication number: 20190055371
    Abstract: Disclosed are compositions of electroactive polymers (EAPs) having improved performance stability. In the EAP compositions, a cross-linked polymer is deposited onto the surface of the EAP by vapor-deposition methods. Upon contact with an aqueous solution (e.g., an aqueous electrolyte solution), the vapor-deposited polymeric network becomes a hydrogel that encapsulates the EAPs. By modulating precursors and vapor deposition conditions, the mesh size of the resultant hydrogel coatings can be controlled to accommodate the key species that interact with the EAPs.

  • Patent number: 9803156
    Abstract: A water-based cutting fluid that comprises water and a water-soluble polyalkylene glycol (PAG) having cloud point from 30° C. to 80° C. The cutting fluid is water-based, i.e., it comprises at least 50 percent by weight (wt %) water. The cutting fluids are well suited for use with diamond wiresaws for the cutting of silicon ingots. The fluids exhibit one or more of low hydrogen generation, no wafer cleaning issues, good lubricity, good cooling efficiency, good swarf suspension and dispersion, low foaming, are generally non-sensitive to metal ions, and are nonflammable.
