  • Polarizable ion-conducting material
    Patent number: 9343240
    Abstract: A polarizable ion-conducting material. The material contains mobile ions and a matrix formed of a polymer having ionic groups of a charge opposite to that of the mobile ions, wherein the material has a polarization of at least 0.2 mC/g, a capacitance of at least 0.1 mF/g, and a polarization retention time of at least 5 seconds. Also disclosed is a device containing such a polarizable ion-conducting material.
    Type: Grant
    Filed: July 30, 2012
    Date of Patent: May 17, 2016
    Assignee: National University of Singapore
    Inventor: Xian Ning Xie
  • Superhydrophilic and water-capturing surfaces
    Patent number: 9150735
    Abstract: A coated substrate includes a substrate and a coating containing a water insoluble polymer and a water soluble polymer, the two polymers, due to different water affinity, forming a nanosegregant on the substrate. Also disclosed are a method of preparing the above-described coated substrate and the use of this coated substrate in a solid-state supercapacitor.
