    Author : Henrik Olsson; Leif Nyholm; Maria Strømme; Martin Sjödin; Johan Bobacka; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polypyrrole; Nanocomposites; Energy storage; Conducting polymers; Cellulose; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : The world’s increased energy storage demand, as well as the environmental concerns related to the combustion of fossil fuels, has triggered a transition to intermittent renewable energy sources as well as to electrical and hybrid vehicles. Current day rechargeable batteries are, due to the invention and development of lithium ion batteries, technologically well positioned to answer to some of these demands. READ MORE

  4. 2. Development of Cellulose-Based, Nanostructured, Conductive Paper for Biomolecular Extraction and Energy Storage Applications

    Author : Aamir Razaq; Albert Mihranyan; Srømme Maria; Leif Nyholm; Johan Bobacka; Uppsala universitet; []
    Keywords : Polypyrrole; Cladophora cellulose; Conductive paper; Electrochemically controlled ion-exchange; DNA extraction; Paper-based energy storage devices; Chopped Carbon fibers; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Abstract : Conductive paper materials consisting of conductive polymers and cellulose are promising for high-tech applications (energy storage and biosciences) due to outstanding aspects of environmental friendliness, mechanical flexibility, electrical conductivity and efficient electroactive behavior. Recently, a conductive composite paper material was developed by covering the individual nanofibers of cellulose from the green algae Cladophora with a polypyrrole (PPy) layer. READ MORE
