Ultrasound mediation for one-pot sonosynthesis and deposition of magnetite nanoparticles on cotton/polyester fabric as a novel magnetic, photocatalytic, sonocatalytic, antibacterial and antifungal textile

Abstract

A magnetic cotton/polyester fabric with photocatalytic, sonocatalytic, antibacterial and antifungal activities was successfully prepared through in-situ sonosynthesis method under ultrasound irradiation. The process involved the oxidation of Fe(2+) to Fe(3+) via hydroxyl radicals generated through bubbles collapse in ultrasonic bath. The treated samples were analyzed by X-ray diffraction, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy and vibrating sample magnetometry. Photocatalytic and sonocatalytic activities of magnetite treated fabrics were also evaluated toward Reactive Blue 2 decoloration under sunlight and ultrasound irradiation. Central composite design based on response surface methodology was applied to study the influence of iron precursor, pH and surfactant concentration to obtain appropriate amount for the best magnetism. Findings suggested the potential of one-pot sonochemical method to synthesize and fabricate Fe3O4 nanoparticles on cotton/polyester fabric possessing appropriate saturation magnetization, 95% antibacterial efficiency against Staphylococcus aureus and 99% antifungal effect against Candida albicans, 87% and 70% dye photocatalytic and sonocatalytic decoloration along with enhanced mechanical properties using only one iron rich precursor at low temperature.

Modification of Cotton Fibers with Magnetite and Magnetic Core‐Shell Mesoporous Silica Nanoparticles

“…XRD pattern of clean cotton sample exhibits the characteristics peaks associated with the crystalline cellulose structure at 16° and 22.5° which correspond to the reflections (110) and (200) respectively . The XRD pattern of sample CF‐2 (Cotton‐Fe 3 O 4 ) shows the characteristic peaks of both cellulose and magnetite, indicating a succesful attaching of Fe 3 O 4 nanoparticles onto the cotton fibers . Similarly, the XRD pattern of sample CF‐3 (Cotton‐Fe 3 O 4 ‐mSiO 2 ) indicates a weakened intensity of the representative peaks due to the presence of the mSiO 2 shell and the overlaping of cotton functional groups…”

The effect of TiO2 nanopigment on the optical properties of polyester fabric in UV–VIS–NIR regions

“…The interest for immobilization of titanium dioxide (TiO 2 ) nanoparticle onto textile material is continually growing due to their extraordinary photocatalytic activity, nontoxicity, high availability, biocompatibility, and low price . Accordingly, much effort have been made to immobilize TiO 2 nanoparticle onto textile materials with an aim to produce goods with multifunctional properties such as ultraviolet protective, self‐cleaning and deodorizing, antimicrobial, and so on …”

“…5,6 Accordingly, much effort have been made to immobilize TiO 2 nanoparticle onto textile materials with an aim to produce goods with multifunctional properties such as ultraviolet protective, 7 self-cleaning 8 and deodorizing, 9,10 antimicrobial, 11,12 and so on. 13,14 In addition, taking complex refractive index into consideration, TiO 2 nanoparticles are inorganic substances possessing some special optical properties. Investigations 15 show that the imaginary part (k) of refractive index for TiO 2 particles has maximum value in the ultraviolet (UV) region, and therefore, it can be expected that the titanium dioxide pigments are good absorbers of ultraviolet radiation.…”

A review of antimicrobial fabric containing nanostructures metal‐based compound

“…Meanwhile, it reduces the features such as poor moisture absorption and static dissipation from polyester and poor crease retention and wrinkle recovery from cotton . Rastgoo et al have studied to produce blended polyester/cotton fabric with antibacterial, magnetic, photoactive, and sonocatalytic properties via sonosynthesis of magnetite iron oxide NPs . Hanh et al have immobilized Ag NPs on peco bed sheets (65% polyester, 35% cotton) for antibacterial performance evaluation .…”
