Sonochemical coating of silver nanoparticles on textile fabrics (nylon, polyester and cotton) and their antibacterial activity

Abstract

Silver nanoparticles were synthesized and deposited on different types of fabrics using ultrasound irradiation. The structure of silver-fabric composites was studied by physico-chemical methods. The mechanism of the strong adhesion of silver nanoparticles to the fibers is discussed. The excellent antibacterial activity of the Ag-fabric composite against Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) cultures was demonstrated.

Numerical simulation of the nonlinear ultrasonic pressure wave propagation in a cavitating bubbly liquid inside a sonochemical reactor

“…The obtained distribution of the cavitation zones closely relates to the coating of the textile as the corresponding jet and collapse events significantly contribute to the nanoparticles' impregnation process (e.g. ZnO and MgO) [13,14,15,16]. The designed sonoreactor consists of three cylindrical transducers, each emitting pressure waves at 20 kHz.…”

“…Silver nanoparticles have been the prime focus of the nanoparticles' research industry due to their unique thermal (Moon et al 2005), electrical (Chen et al 2009) and optical (Kelly et al 2003) properties and also because of the use of these structures in products that range from photovoltaics (Yoon et al 2010) to biological and chemical sensors (McFarland and Van Duyne 2003). Also nanosilver has been used extensively as an anti-bacterial agent in the health industry (Jain and Pradeep 2005), food storage (Costa et al 2011), textile coatings (Perelshtein et al 2008) and also for a number of environmental applications (Li et al 2008). Currently nanosilver is prepared by different methods including electrolysis, physical, chemical, and biological methods (Dubey et al 2010;Usha Rani and Reddy 2011).…”

Novel process for coating textile materials with silver to prepare antimicrobial fabrics

“…Many methods to apply metal films on non-metallic materials have been presented; these can be potentially used for deposition of silver films [16][17][18][19][20][21][22][23][24][25][26][27]. Among these, the most frequently used is the so-called "physical and chemical methods".…”

“…Another approach for chemical deposition of metal coatings employs reducing agents that are either in the gas phase or dissolved in an electrolyte solution [21][22][23][24]. Gaseous hydrogen can be used in reduction reactions performed at high temperatures, in the order of several hundred degrees.…”

“…For the application of silver nanoparticles on fabrics a method that combines chemical reduction and physical adsorption by ultrasound has been also proposed [24]. A cotton 5 sample is placed in a solution of silver nitrate in the presence of aqueous ethylene glycol and ammonium hydroxide, and then it is subjected to ultrasonic treatment.…”
