“…According to the previously reported method, the antifungal behavior of PMETM was investigated by the fungal landing test. 41 PMETM powder was pressed into regular pellets (diameter = 13 mm, thickness = 0.75 mm), and PET pellets were used as a control for the same test. The material was immobilized separately on the surface of wort agar medium.…”

“…The material was immobilized separately on the surface of wort agar medium. Then, 10 μL of the pre-prepared black fungal suspension (detailed preparation can be found in the literature 41 ) was dropped into the center of the plate with a distance of about 15 mm from the pellets. Finally, the medium was placed in a fungal incubator at 30 °C, and photographs were taken at regular intervals to record the experimental phenomena.…”

Antimicrobial modification of poly(ethylene terephthalate) (PET) is effective in preventing the adhesion and growth of microorganisms on its surface. However, few methods are available to modify PET directly at its backbone to impart the antimicrobial effect. Herein, menthoxytriazine-modified PET (PMETM) based on the stereochemical antimicrobial strategy was reported. This novel PET was prepared by inserting menthoxytriazine into the PET backbone. The antibacterial adhesion test and the antifungal landing test were employed to confirm the antiadhesion ability of PMETM. PMETM could effectively inhibit the adhesion of bacteria, with inhibition ratios of 99.9 and 99.7% against Escherichia coli (Gram-negative) and Bacillus subtilis (Gram-positive), respectively. In addition, PMETM exhibited excellent resistance to Aspergillus niger (fungal) contamination for more than 30 days. Cytotoxicity assays indicated that PMETM was a noncytotoxic material. These results suggested that the insertion of menthoxytriazine in the PET backbone was a promising strategy to confer antimicrobial properties to PET.

Dual Coordination between Stereochemistry and Cations Endows Polyethylene Terephthalate Fabrics with Diversiform Antimicrobial Abilities for Attack and Defense

Modification of fabrics by stereochemical antiadhesion strategies is an emerging approach to antimicrobial fabric finishing. However, a purely antiadhesive fabric cannot avoid the passive adhesion of pathogenic microorganisms. To address this issue, borneol 4formylbenzoate (BF) with a stereochemical structure is introduced into a cationic polymer PEI-modified PET fabric by a simple two-step method. The obtained fabric exhibits remarkable features of high bactericidal activity, excellent resistance to bacterial adhesion, desirable fungal repellent performance, and low cytotoxicity. More impressively, this modified fabric not only effectively reduces microbial contamination during food preservation but also plays a role in avoiding infection and accelerating wound healing in the mouse wound model. The dual coordination between stereochemistry and cations is validated as a viable "attack and defense" antimicrobial strategy, providing an effective guide for diversiform antimicrobial designs.

“…The menthoxy polymer P(MT- alt -ODA) forms a molecular prison of spores, where the fungi were firmly confined. The menthoxy polymer is a candidate of a stereochemical antifungal strategy ,, and will be promising for managing and controlling microorganisms. This strategy can effectively limit fungi landing on the materials surface, so as to prevent fungal contaminations.…”

An antifungal polymer containing menthoxy triazine was synthesized by a polycondensation of 2,4-dichloro-6-menthoxy-1,3,5-triazine (DMT) with 4,4-oxidianiline (ODA) and named as P(MT-alt-ODA). To emphasize the antifungal performance of the menthoxy group, series of similar triazine polymers derived correspondingly with hydrogen, ethoxy, and decoxy groups were prepared and served as controls. The spores of Aspergillus niger were used for an antifungal evaluation. Only P(MT-alt-ODA) can effectively inhibit the growth and spread of spores. A further in-depth analysis combined with an inhibition zone and water contact angle illustrated that the surface menthoxy stereochemistry is crucial for the antifungal mechanism.
