摘要： A polymer composite exhibiting piezoelectric properties can be formed for flexible and/or thin film applications, in which the polymer composite includes a polymer matrix and a piezoelectric ceramic filler embedded in the polymer matrix. The polymer matrix may include at least two polymers: a first polymer and a second polymer. The first polymer may be a fluorinated polymer, and the second polymer may be compatible with the first polymer and have a dielectric constant of less than approximately 20. The piezoelectric ceramic filler can be lithium doped potassium sodium niobite (KNLN), and be approximately 40-70% by volume of the polymer composite. The remaining 30-60% by volume may be the polymer matrix, which may itself be approximately 5-20% by weight second polymer and 80-95% fluorinated polymer.

摘要： The present application describes the development of a method for creating a continuous conductive metal layer on a surface of a component, the component preferably made of molded acrylonitrile butadiene styrene polymer (ABS) or polycarbonate/ABS (PC/ABS) blend, the method utilizing cold sintering. This method avoids the need for chromic acid etching pretreatment prior to the electroplating process. Continuous, conductive and thickness-controllable layers of metals such as Ni, Fe, Cu or Ni/Fe have been created on the plastic surface using the cold sintering. The method will also work with any other metal. Thus, molded ABS or PC/ABS parts can be further electroplated without the need to go through the undesirable etching process.

摘要： A process for making ultra-fine particles of a high performance polymer in a yield greater than 90%, which includes dissolving the high performance polymer in an organic solvent capable of dissolving the polymer to form a solution; emulsifying the solution by combining the solution with water and a surfactant to form an emulsion; transferring the emulsion into a receiving water containing a surfactant to remove the organic solvent and form a slurry; and recovering particles of less than 75 microns in diameter in a yield greater than 90%.
