Electric heated cotton fabrics with durable conductivity and self-cleaning properties

Abstract

This study was carried out to improve durability and reduce conductivity degradation of polypyrrole-deposited cotton fabrics by introducting a superhydrophobic surface.

Integration of Polypyrrole Electrode into Piezoelectric PVDF Energy Harvester with Improved Adhesion and Over-Oxidation Resistance

“…It was thought that A120PH would have the highest water contact angle due to the introduction of nanostructures by polymerization and the surface energy lowered by DTMS coating. However, this was a lower value than was reported previously for a hydrophobic DTMS coating on the fabric [45,59]. Fabrics are comprised of yarns, which provide intrinsic microscale roughness, and additional nanostructures are very effective for creating a hierarchical roughness to ensure the superhydrophobicity and the minimum contact area with water [59].…”

“…Electrodes were obtained through the polymerization of PPy on the PVDF film surfaces according to a previously reported method [43,44,45]. Pyrrole (0.69 mL) and AQSA-Na (0.41 g, 1.25 mmol) were dissolved in 50 mL of distilled water to yield solution A. FeCl 3 ·6H 2 O (2.7 g, 0.01 mol) was dissolved in 50 mL of distilled water to yield solution B.…”

Functional Fibers, Composites and Textiles Utilizing Photothermal and Joule Heating

“…For example, PPy was synthesized on the surfaces of cotton and nylon fabrics via in-situ polymerization with FeCl 3 [125][126][127]. The operating temperature of the resulting Joule heaters based on PPy-coated cotton fabrics was in the range of 28-83 • C at an operating voltage of 3-9 V with a sheet resistance of 303 Ωsq −1 [127] and demonstrated multifunctionalities with superhydrophobicity and self-cleaning effects [126]. voltage of 2 V. As a representative organic conductive material, conjugated polymers such as polyaniline, poly (3,4-ethylenedioxythiophene) and PPy could be coated on fabrics by a vapor phase polymerization, an electrochemical polymerization, in-situ solution polymerization or inkjet/blade printing, as recently reviewed [124].…”
