Highly Ordered Arrays of Silver Nanowires for Transparent Conducting PET Film 

Abstract

Silver nanowires (AgNWs) with ultra-high purity and high yield are successfully synthesized by employing a modified facile polyol method using PVP as capping and stabilizing agent. The reaction is carried out at a moderate temperature of 140 °C and mild stirring rate for about 3 hours. The prepared AgNWs are characterized by UV-Vis spectroscopy, scanning electron microscopy (SEM), X-rays diffraction (XRD) and PL spectroscopy. The luminescent AgNWs exhibit red emission which is accredited to the deep holes. The SEM results confirm the formation of AgNWs of length ranging from 35 to 40 µm and an average diameter of about 86 nm, thus their aspect ratios exceed 400. The AgNWs and hydroxyethyl cellulose (HEC) based ink is transferred to polyethylene terephthalate (PET) film by simple mechanical pressing. The PET film has retained its transparency and flexibility after AgNWs ink coating. The % transmittance of as-prepared PET film is estimated to be about 92.5% with a lower sheet resistance value ~ 20 Ω, which can make it a potential substitute to commonly used expensive indium tin oxide (ITO) films in the field of optoelectronics.

Recent Studies on Recycled PET Fibers: Production and Applications: a Review

“…(5) Further condensation is done during a solid-state post-condensation (SSP) mechanism that makes crystalline pellets (Duh 2002;Mendiburu et al 2020;Wang et al 2019;Welle 2011;Ravindranath and Mashelkar 1984). PET is produced in 4 commercial grades, which are fiber (textile, and technical and tire cord), film (biaxially oriented PET film, and sheet grade for thermoforming), bottle (water bottles and carbonated soft drink), and monofilament (Gharde 2020;Naz et al 2020;Bethke et al 2020;Anjum et al 2020).
