CNF thin films as sustainable carrier material and their functionalization for energy applications — •Marie Betker1,2, Constantin Harder1,3, Marc Gensch1,3, Calvin Brett1,2, Matthias Schwartzkopf1, Andrei Chumakov1, Qing Chen1, Daniel Söderberg2, and Stephan Roth1,2 — 1Deutsches Elektronen Synchrotron, Notkestrasse 85, 22607 Hamburg, Germany — 2KTH Royal Institute of Technology, Teknikringen 8, 10044 Stockholm, Sweden — 3Physik-Department E13, Technische Universität München, James-Franck-Str. 1, 85748 Garching, Germany
Sustainable carrier materials will play an important role in the design of future functional items. One matching candidate for that purpose are cellulose nanofibrils (CNF) with their many beneficial properties: It is lightweight, transparent, flexible and recyclable, and can therefore be used as template for thin-film applications. Spray deposition is a suitable technique to fabricated thin, homogeneous films of large scale and with a ultra-low roughness, which make it fitting for industrial applications. It can also be used to functionalize and thus to implement functional, nanostructured films and multi-component systems. The deposition of conductive silver nanowires as flexible electrodes, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate as blocking layer and of the photoactive layer poly(3-hexylthiophene) and [6,6]-phenyl C61-butyric acid methylester on nanostructured CNF thin films was studied in situ using GISAXS. Important insights into possible templating effects of CNF and into the interactions between the CNF-layers and the functional materials could be gained.
