PVP a binder for the manufacture of ultrathin ITO/polymer nanocomposite films with improved electrical conductivity

Abstract

This paper presents the manufacture of ultrathin (\1 lm) transparent conductive indium tin oxide (ITO) films based on nanoparticulate ITO slurries by the profile rod technique using the binder polyvinyl pyrrolidone (PVP) as an organic additive. The influence of the slurry composition on the film thickness and the specific electrical resistance as well as the transmission of the dried films is evaluated. The organic solvent ethanol and different types of the PVP binder were tested for slurry preparation and layer performance. ITO green films with low specific electrical resistance of 3 X cm, 87 % inline transmission, and layer thicknesses of only 250 nm could be manufactured. Furthermore, the influence of heat treatments up to 400°C on the electrical properties of the ITO films was evaluated.

Polyvinyl pyrrolidone (PVP) as an efficient and biocompatible binder for metal alloy processing: A case study with Ti‐20Zr‐11Nb‐3Sn

“…PVP being a biocompatible and functional polymer showing its efficacy to bind and stabilize reactive (rather highly unstable) metal nanoparticles (e.g., silver nanoparticle: Ag°), has been chosen here as a binder to stabilize and binding the metal powders (including highly reactive Zr) 47–51 . The pre‐mixed alloying metals were mixed with the ethanolic dispersion PVP to bind the metals altogether and maintain their stability 52,53 . The PVP was found to stabilize the alloying metals in their elemental state for 30 days while maintaining the expected stoichiometry of the bound metals.…”

“…[47][48][49][50][51] The premixed alloying metals were mixed with the ethanolic dispersion PVP to bind the metals altogether and maintain their stability. 52,53 The PVP was found to stabilize the alloying metals in their elemental state for 30 days while maintaining the expected stoichiometry of the bound metals. The thermal debinding of the PVP-bound metal particles was investigated at two different temperatures 600 and 1000 C under an inert atmosphere.…”

Enhanced electrical conductivity and structural, mechanical characterization of standalone poly(vinyl alcohol)‐graphite nanoplatelets composite films

“…However, owing to the elastic nature of polymers, the casting method required for polymer composites are different from that used in ceramics. [30][31][32]34 Thus, we report the processing of standalone PVA-GnP composite films using a modified casting method. Here the slurry preparation will be similar to the solution casting method.…”

“…Tape casting of conducting fillers or carbon‐based composites of PVA is not reported yet. However, owing to the elastic nature of polymers, the casting method required for polymer composites are different from that used in ceramics 30–32,34 . Thus, we report the processing of standalone PVA–GnP composite films using a modified casting method.…”
