Vapor phase organic chemistry to deposit conjugated polymer films on arbitrary substrates
نویسندگان
چکیده
Coating textured, high surface area substrates, such as paper and textiles, with conjugated polymer films is challenging. Selected vapor deposition techniques allow for the film forming process to be largely divorced of substrate properties, such as surface energy and surface roughness, and have the potential to yield conformal coatings. However, reliable vapor deposition techniques with which to fabricate structurally-diverse conjugated polymer films do not exist. Here, we report two vapor deposition chambers that, combined, allow for in situ vapor phase polymerization of a representative selection of common conjugated monomers. Conformal coating of highly disordered, high surface area threedimensional substrates, including a cotton towel and corduroy fabric, with either conductive PEDOT or poly(thieno[3,2-b]thiophene) films of precisely-controlled thickness is described.

Photovoltaics are an important power source for both off-grid terrestrial and extraterrestrial use. Thin film polycrystalline materials have been studied extensively for solar cell applications partially because their polycrystalline nature allows their formation on many different types of substrates including glass, metal foil, and lightweight flexible polymer substrates. For example, monolith...

DOI: 10.1002/admi.201700873 transport.[20] When interfaced with an electrolyte, redox events in conjugated poly mer films are also accompanied by film swelling or deswelling due to ion and/or solvent diffusion into or out of the films, respectively. The response times and fatigue resistances of devices that subject electroactive films to periodic cycles of oxidation/reduction are, thus, crucial...
