“…This may be due to the low critical micelle concentration (CMC) values of amphiphilic block copolymers. Most reported work focused on antimicrobial block copolymers are related to antimicrobial micelles or nanoobjects [86e88], antimicrobial fibers [89] and surface coatings [90,91].…”

“…Other biocide compounds have been also mixed into electrospinning solution as chlorhexidine [ 138 ] in cellulose acetate or amine groups [ 139 ] in PAN. In another approach reported by Kayaci et al [ 140 ], triclosan (TR) have been complexed with cyclodextrin (CD) and mixed with PLA.…”

Nanoparticles are very interesting because of their surface properties, different from bulk materials. Such properties make possible to endow ordinary products with new functionalities. Their relatively low cost with respect to other nano-additives make them a promising choice for industrial mass-production systems. Nanoparticles of different kind of materials such as silver, titania, and zinc oxide have been used in the functionalization of fibers and fabrics achieving significantly improved products with new macroscopic properties. This article reviews the most relevant approaches for incorporating such nanoparticles into synthetic fibers used traditionally in the textile industry allowing to give a solution to traditional problems for textiles such as the microorganism growth onto fibers, flammability, robustness against ultraviolet radiation, and many others. In addition, the incorporation of such nanoparticles into special ultrathin fibers is also analyzed. In this field, electrospinning is a very promising technique that allows the fabrication of ultrathin fiber mats with an extraordinary control of their structure and properties, being an ideal alternative for applications such as wound healing or even functional membranes.

“…Various biocides such as silver nanoparticles, quaternary ammonium salts or their derivatives, compounds with biguanide groups, and N-halamine have been incorporated into electrospun fiber membranes to serve as antimicrobial filters or to create biological protective clothing [46][47][48]. Silver ions and silver compounds have long been recognized as potent antimicrobial agents.…”

“…However, this was still much higher than the untreated nanofibers which had a bacterial reduction rate of 5-10 %. In another work, quaternary ammonium salts generated on electrospun diblock copolymers by N-alkylation of tertiary amine groups were tested for their antibacterial efficiency [47]. The nanofibers were found to exhibit high antibacterial characteristics with 95 % of E. coli and 97 % S. aureus killed within 10 min of contact with 50 mg of fibers.…”
