Enhanced adhesion of polypyrrole/PW₁₂O hybrid coatings on polyester fabrics

Abstract

J. Molina). IntroductionThe development of textiles with new properties and applications has received great attention during the last years; one of these properties is the electrical conductivity. One One of the drawbacks of the chemical synthesis of polypyrrole on fabrics is the poor adhesion between the fibers and the polypyrrole coating. This makes that their mechanical properties are not as good as it would be desired. The polymerization of pyrrole is quite independent of the substrate. Only the polarity of the surface may have an effect on the adhesion of the conducting polymer. The adhesion is worse with fibers without polar groups (polyethylene for example) [10]. A way to improve the durability of the coating is to increase the surface energy of the fibers. Plasma treatments have

Physical, Chemical and Morphological Characterization of Polyamide Fabrics Treated with Plasma Discharge

“…This technique allows quantifying quickly the chemical composition obtained promptly after plasma discharge application. However, EDS is not the most adequate technique to evaluate carbon content after plasma treatment, thus for a more accurate study of the surface modifications provoked by plasma species interaction, the XPS technique is the most commonly mentioned in the literature [36][37][38] and the results obtained with this important technique can be observed in table 5.…”

“…The surface modification of different polymers using plasma technology has received great attention during the last years [1][2][3][4][5] . In fact, plasma treatment has assumed a great importance among all available surface alteration processes.…”

Applications of Polypyrrole/Polyester Textiles: A Review

“…The study gives the result that both the increase in surface functionalisation by carboxylic groups and formation of nano-size roughness contributed to improved adhesion and conductivity. Also in [57], we can find researches on plasma treatments of polyester fabrics to increase polypyrrole/PW 12 O 40 3− adhesion. In the reference it is told that the roughness of the fibres increases as it has been observed by means of atomic force microscopy (AFM).…”

“…Coatings obtained on plasma treated fabrics were more resistant to washing and rubbing fastness tests. As explained in [57], the use of the counter ion (PW 12 ) that contains an element with a high atomic number (W) helps to locate the zones where the coating is missed. This control is achieved by means of micrographs obtained by backscattered electrons (BSE).…”

Plasma treatment of polyester fabrics to increase the adhesion of reduced graphene oxide

“…In the present paper the adsorption/reduction strategy has been employed to produce RGO coated polyester fabrics. Plasma techniques have been widely used to increase the adhesion between different materials, including polymers [30]. Plasma treatment produces reactive groups and radicals on the surface of treated fabrics.…”
