Preparation and characterization of polypropylene/silver nanocomposite fibers

Abstract

Bicomponent sheath‐core fibers were prepared by a general melt‐spinning method with polypropylene chips and silver nanoparticles. The melt‐spun fibers were characterized by DSC, WAXS and SEM. The antibacterial effect was evaluated by an AATCC 100 test, a quantitative method. The results of the DSC thermogram and the intensity pattern of X‐ray diffraction indicated that the crystallinity of polypropylene including silver nanoparticles was slightly decreased compared with that of pure polypropylene fibers. SEM micrographs showed that the average diameter of the silver nanoparticles was approximately 30 nm and some particles had aggregated. The fibers, which contained silver in the core part, did not show antibacterial effects. Fibers with added silver in the sheath part, however, exhibited excellent antibacterial effects.

Effect of Newly Synthesized Polypropylene/Silver Nonwoven Fabric Dressing on Incisional Wound Healing in Rats

“…As silver is non-toxic and posses antimicrobial properties, it has encouraged workers to use silver nanoparticles in different textile fabrics. In this direction, silver nanocomposite fibres were prepared containing silver nanoparticles incorporated inside the fabric [11]. Thus, various silver-based dressings have been introduced and have become the latest and greatest ''innovation'' in wound care products.…”

Review of Antibacterial Activity of Titanium-based Implants Surfaces Fabricated by Micro-arc Oxidation

“…It has also been demonstrated that the antimicrobial activity of Ag NPs is higher than that of Ag ion [73]. The use of Ag NPs will lead to anti-bacterial effects maximized due to the increased numbers of particles per unit area [67]. Necula et al [55] have successfully fabricated Ag-bearing TiO2 coatings with different contents of Ag NPs by MAO in the electrolyte including CA, calcium glycerophosphate (Ca-GP) with Ag NPs.…”

“…NPs present a greater chemical activity than the bulk material for the advantage of their larger ratio of surface area to volume [67]. Ag NPs are the most popular inorganic antimicrobial NPs [68] and can be incorporated into implant by directly dispersion of solid Ag NPs in the electrolyte during MAO.…”

Preparation and Characterization of Nylon 6/Silver Nanocomposite Fibers for Permanent Antibacterial Effect

“…Polymeric or fibrous nanocomposites of polymers and silver nanoparticle have been reported to have special properties. [17][18] Nanocomposite fibers have attracted attention in recent years because improved mechanical, thermal, solvent resistance ad fire retardant properties compare to the pure or conventional composite fibers. Therefore, much work has focused on developing nanocomposite fibers using various polymers.…”

“…In addition, a coating of nano-particles on fabrics will not affect their breathability or hand feel. 7 For imparting anti-bacterial properties, nanosized silver, [8][9][10][11][12] titanium dioxide [13][14][15] and zinc oxides are used. Metallic ions and metallic compounds display a certain degree of sterilizing effect.…”
