摘要： A piezoelectric fabric can include: a non-woven, continuous fiber mat comprising: a polymer; and a plurality of piezoelectric ceramic particles. The piezoelectric fabric can be produced by electrospinning. The method of electrospinning can include: forming a continuous fiber of material comprising: flowing a fluid through a needle, wherein the fluid comprises: the polymer; a base fluid; and the piezoelectric ceramic particles; and applying a voltage to create an electric field between a tip of the needle and a collector during fluid flow; and collecting the continuous fiber on the collector. The piezoelectric fabric can exhibit improved performance and piezo thermal stability.

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.
