“…Plasma-treated materials exhibit a variety of nanostructures: lamella structures for PET textiles [23,24], flat-capped nanograss (20-80 nm diameter, 0.5 µm height) [43] and sharp nanoneedle (0.5-20 µm) [45] structures for black silicon, and a sharp nanocone structure (10-40 nm tip, 0.4-1.2 µm width, 3-5 µm height) for diamond [9].

“…Compared to stiff materials (e.g., silicon [7], graphene [8], diamond [9], graphene oxide [11], titanium [12], or titanium oxide [13]), soft polymers have received relatively little study for use in antibacterial nanostructured surfaces through biophysical interactions with the bacterial membrane [19,[23][24][25][26][27]. Some studies have found that the antibacterial activity of polyethylene terephthalate (PET) films was enhanced when the physical bactericidal mechanism was activated by modifying the surface structures via cold oxygen plasma [23,24] and nanoimprint lithography [19,25] treatments. Plasma treatment, often used for dry-etching using energetic atoms or molecules, is a useful technique for heat-sensitive materials such as polymers.…”

Cross-infection following cross-contamination is a serious social issue worldwide. Pathogens are normally spread by contact with germ-contaminated surfaces. Accordingly, antibacterial surface technologies are urgently needed and have consequently been actively developed in recent years. Among these technologies, biomimetic nanopatterned surfaces that physically kill adhering bacteria have attracted attraction as an effective technological solution to replace toxic chemical disinfectants (biocides). Herein, we introduce a transparent, colorless, and self-disinfecting polyethylene terephthalate (PET) film that mimics the surface structure of the Progomphus obscurus (sanddragon) wing physically killing the attached bacteria. The PET film was partially etched via a 4-min carbon tetrafluoride (CF4) plasma treatment. Compared to a flat bare PET film, the plasma-treated film surface exhibited a uniform array structure composed of nanopillars with a 30 nm diameter, 237 nm height, and 75 nm pitch. The plasma-treated PET film showed improvements in optical properties (transmittance and B*) and antibacterial effectiveness over the bare film; the transparency and colorlessness slightly increased, and the antibacterial activity increased from 53.8 to 100% for Staphylococcus aureus, and from 0 to 100% for Escherichia coli. These results demonstrated the feasibility of the CF4 plasma-treated PET film as a potential antibacterial overcoating with good optical properties.

“…Higher activity of modified nonwovens against S. aureus than for K. pneumoniae reflects higher activity of triclosan against Gram (+) bacteria . Triclosan inhibits the growth of S. aureus (ATCC 6538) at 0.01 ppm concentration, whereas K. pneumoniae (ATCC 4352) at concentration 0.03 ppm.…”

“…Triclosan [5‐chloro‐2‐(2,4‐dichlorophenoxy)phenol] could be incorporated into textiles during their fabrication and finishing . As a finishing substance, triclosan is often used for the production of industrial and transport filters, antimicrobial shoe socks, towels, cleaning wipes, and household textiles . One of the nowadays, developing methods is based on binding the biocide‐loaded (bio) degradable microparticles to the desired textiles.…”

A convenient and simple method for preparation of commercial nonwovens with antimicrobial properties was elaborated. The process consists in preparation of poly(L-lactide) microspheres (from poly(L-lactide) with M n = 10,560 and M w /M n = 1.39) containing triclosan (5-chloro-2-(2,4-dichlorophenoxy) phenol) and loading them onto the nonwovens. The microspheres were prepared by spray drying (D n = 3.91 μm, D w /D n = 2.43) and oil-in-water emulsification-solvent evaporation method (D n = 5.84 μm, D w /D n = 1.25). Content of triclosan in microspheres ranged from 4.65 to 4.95 wt%. The antibacterial nonwovens were prepared by padding of the fibers with the microspheres using the microsphere suspension. The resulting antibacterial nonwovens were examined using inhibition zone measurement method. Inhibition zones from 4 to 9 mm indicated that the modified nonwovens had antibacterial properties against Gram (+)-Staphylococcus aureus and Gram (À)-Klebsiella pneumoniae. Nonwovens were conditioned up to 12 months at relative humidity <5%, 50%, and 100% in desiccators and up to 6 months air-conditioning system at relative humidity = 65%. Antimicrobial activity of the modified nonwovens was examined as a function of time and air humidity. Time of conditioning has strong influence on antibacterial activity, whereas the impact of the air humidity was negligible. All nonwovens had antibacterial properties even after 12 months of conditioning.

“…A broad range of antimicrobial textile products, for example, hygienic clothing, underwear, socks, shoe linings, outdoor textiles, air filters, automotive textiles, domestic home furnishings, and medical textiles have been developed to respond the substantial demand. Generally, the antimicrobial activity of textiles results from antimicrobial agents, such as quaternary ammonium compounds, triclosan, polyhexamethylene biguanide (PHMB) noble metals, and metal oxides (TiO 2 , ZnO). Because most of the antimicrobials cannot be chemically linked to textile fibers, the antimicrobial efficiency of the leaching agents directly depends on their concentration and does not withstand repeated laundering processes.…”

An N-halamine monomer, 3-allyl-5,5-dimethylhydantoin (ADMH), was synthesized by a Gabriel reaction of 5,5-dimethylhydantoin and 3-bromopropene. Antimicrobial coatings of poly[1-(4,4-dimethyl-2,5-dioxoimidazolidin-1-methyl)ethylene] were prepared on plasma-treated PET fabrics via a vapor-phase assisted polymerization (VAP) process using gasified ADMH as monomer. The coatings endow the PET fabrics with an antimicrobial efficiency greater than 80% for both Escherichia coli and Staphylococcus aureus after chlorination of the N-halamine polymer with dilute bleach solution. The obtained antimicrobial effect has remarkable durability that can bear over 30 times of stringent laundering tests. Compared with other antimicrobial finishing methods, the VAP methodology offers great advantages in needless of organic solvents and small consumption of monomer. It has potential applications in a wide variety of fields such as hygienic clothing, underwear, socks, and medical textiles.
