Journal ArticleDOI
Vapor-phase polymerization of nanofibrillar poly(3,4-ethylenedioxythiophene) for supercapacitors.
Julio M. D’Arcy,Maher F. El-Kady,Maher F. El-Kady,Pwint P Khine,Linghong Zhang,Sun Hwa Lee,Nicole R. Davis,David S. Liu,Michael T. Yeung,Sung Yeol Kim,Christopher L. Turner,Andrew T. Lech,Paula T. Hammond,Richard B. Kaner +13 more
TL;DR: A simple process is introduced that overcomes drawbacks and results in vertically directed high aspect ratio poly(3,4-ethylenedioxythiophene) nanofibers possessing a high conductivity of 130 S/cm.
Journal ArticleDOI
Spray Layer-by-Layer Electrospun Composite Proton Exchange Membranes
David S. Liu,J. Nathan Ashcraft,Matthew M. Mannarino,Meredith N. Silberstein,Avni A. Argun,Gregory C. Rutledge,Mary C. Boyce,Paula T. Hammond +7 more
TL;DR: In this paper, three different and unique composite film morphologies can be achieved in which the electrospun mat provided mechanical support; the LbL assembly produces highly conductive films that coat the mat in a controlled fashion, separately providing the ionic conductivity and fuel blocking characteristics of the composite membrane.
Journal ArticleDOI
Li-Anode Protective Layers for Li Rechargeable Batteries via Layer-by-Layer Approaches
Sun Hwa Lee,Jonathon R. Harding,David S. Liu,Julio M. D’Arcy,Yang Shao-Horn,Paula T. Hammond +5 more
TL;DR: In this article, Li-anode protective layers were fabricated using layer-by-layer assembly, which resulted in high ionic conductivity, controlled electrolyte permeability, and high Li-transfer number.
Journal ArticleDOI
Mechanical and transport properties of layer-by-layer electrospun composite proton exchange membranes for fuel cell applications.
TL;DR: In this article, composite membranes composed of highly conductive and selective layer-by-layer (LbL) films and electrospun fiber mats were fabricated and characterized for mechanical strength and electrochemical selectivity.
Journal ArticleDOI
Highly transparent mixed electron and proton conducting polymer membranes
TL;DR: In this article, the authors demonstrate the development of highly transparent proton and electron conducting polymer composites of poly(3,4-ethylenedioxythiophene)/sulfonated poly(2,6-dimethyl 1, 4-phenylene oxide) (PEDOT:sPPO).
