“…coli was obviously displayed in all of the antibacterial fabrics (F8, F9, F10, F11, and F3) as compared to that in the pristine fabric, with an especially great reduction for antibacterial fabrics (F9, F10, F11, and F3) due to the fluorine component. Sivakumar et al previously reported that hydrophilic surfaces prevent bacterial attachment and hydrophobic organisms have a greater propensity to attach to hydrophobic surfaces than hydrophilic ones in their work. However, a few researchers have found that in in vitro environments, hydrophobic surfaces showed less bacterial adhesion when compared to the hydrophilic ones. , Herein, further investigation was undertaken by combining the water contact angles (WCAs) on the treated fabrics and bacterial antiadhesion rates (Figure ).…”

“…The repelling of bacteria was realized by introducing elements, such as highly negatively charged polymers (electrostatic repulsion), similar hydrogel forming polymers (steric repulsion) mostly based on poly(ethylene glycol), or special polymers with low surface energy (ultrahydrophobic repulsion). − The killing of bacteria can be achieved by either release-killing of antibacterial moiety from a matrix or contact-killing of antibacterial surfaces. − Unfortunately, up to now, only a few literatures about antibacterial and bacterially antiadhesive fabrics were reported. For instance, Sivakumar et al have developed a bacterially antiadhesive cotton cloth coated by chalcones . Spasova et al.…”

Considerable attention has been devoted to producing antibacterial fabrics due to their very wide applications in medicine, hygiene, hospital, etc. However, the poor antibacterial durability and bad bacterial antiadhesion capacity of most existing antibacterial fabrics limit their applications. In this work, a series of antibacterial and polymeric quaternary ammonium monomers with different alkyl chain length were successfully synthesized to copolymerize with fluorine-containing and other acrylic monomers to generate cationic fluorinated polymer emulsions and durably antibacterial and bacterially antiadhesive cotton fabrics. The relation between antibacterial constituent and its antibacterial activity was investigated. The study indicated that the alkyl chain length and contents of the antibacterial monomers, as well as the add-on percentage of polymer greatly influenced the antibacterial activities of the fabrics. In addition, it was found that incorporation of fluorine component into the polymer greatly enhanced the antibacterial activity and bacterial antiadhesion of the treated fabrics due to the low surface energy induced hydrophobicity. Finally, antibacterial and antiadhesive models of action of the obtained fabrics were illustrated.

“…These cotton fabrics achieved bacterial antiadhesion mainly by hydrophobicity . Sivakumar et al developed a chalcone coating on cotton cloth to reduce bacterial adhesion . As an alternative, we recently developed a soft “surface stereochemistry” strategy, on the basis of a well‐accepted theory that cells could distinguish molecular chirality, to regulate microbial reversible adhesion in the initial stage of microbe–material interaction .…”

Microbial contamination on cotton textiles (CT) negatively affects people's health as well as the textile itself during use and storage. Using antimicrobial CT in a body‐safe manner is currently still a challenge because it is difficult to balance killing microbes and protecting skin flora. Herein, a borneol‐decorated CT (BDCT) through coupling of borneol 4‐formylbenzoate molecules onto the amino‐modified CT is reported. This BDCT shows strong and broad‐spectrum microbially antiadhesive activities against gram‐positive bacteria (Staphylococcus aureus and S. epidermidis), gram‐negative bacteria (Escherichia coli and Pseudomonas aeruginosa), and fungi (Aspergillus niger, Mucor racemosus, and Candida albicans). Because of its unique stereochemical microbial antiadhesion mechanism, BDCT is harmless to skin flora. In addition, BDCT exhibits prominent durability of microbially antiadhesive capability by bearing 50 times of accelerated laundering. Therefore, this stereochemical BDCT strategy shows great potential for applications in the new generation of textiles, food packaging, and medical protection.

Iron particles were immobilized onto non-woven carbon fiber via electroplating for use in a microbial fuel cell (MFC). Electroplating was performed under an applied voltage at a current of 0.2 A for 5, 10, and 15 min. The scanning electron microscope (SEM) observations show that 5 min was not adequate for the particles to be immobilized, whereas 10 and 15 min of electroplating resulted in an adequate number of particles on the surface. To evaluate the strength of the binding of iron via electroplating on the surface of the fiber, the samples were washed with pure water and observed using an SEM. The 10 min electroplated sample has a larger surface area, which is suitable for the MFC anode, than the 15 min electroplated sample. According to X-ray photoelectron spectroscopy and X-ray diffraction analysis, the peaks corresponded to those of Fe 2 O 3 , and the sample dipped into tannic acid shows the peaks of Fe 3 O 4 . The amount of biofilm of Shewanella oneidensis MR-1 was evaluated using crystal violet staining, and living bacteria were counted as colony forming units. Electroplated Fe 2 O 3 and Fe 3 O 4 were found to be effective for producing biofilm and immobilizing S. oneidensis MR-1.
