| Title: | Energy harvesting with peptide nanotube-graphene oxide flexible substrates prepared with electric field and wettability assisted self-assembly | Authors: | Almohammed, Sawsan; Thampi, Abi; Bazaid, Arwa; Zhang, Fengyuan; Keogh, Kevin; Rice, James H.; Rodriguez, Brian J.; et al. | Permanent link: | http://hdl.handle.net/10197/11993 | Date: | 15-Sep-2020 | Online since: | 2021-03-02T14:49:56Z | Abstract: | Piezoelectric diphenylalanine peptide nanotubes (PNTs) have recently been demonstrated in energy harvesting applications, typically based on vertically aligned PNTs that generate charge when pressed. In this work, we use a wettability difference and an applied electric field to align PNTs and PNT-based composites on flexible substrates. Open-circuit voltages and short-circuit currents exceeding 6 V and 60 nA, respectively, are achieved by bending the substrate, opening up the use of horizontally aligned PNTs as flexible energy harvesting substrates. | Funding Details: | European Commission Horizon 2020 Science Foundation Ireland |
