“…FT-IR and XPS were used to determine the chemical composition and chemical binding state of the treated PET fabrics. After the treatment with APDMH, new absorption peaks appeared at 1712 cm -1 and 1408 cm -1 in the curves of PET-APDMH and PET-APDMH-Cl (Figure 2A), which were attributed to the stretching mode of carbonyl group (-C=O) [51,52] and the bending vibrations of alkyl groups in the N-halamine structure [38], respectively. XPS spectra of PET, PET-PAPDMH, PET-APDMH-Cl were performed, and the results are shown in Figure 2B-E.…”

Antibacterial textile materials are widely used in daily life, but most are disposable products with poor antibacterial durability. N-halamine can rapidly inactivate microorganisms, has good stability, and shows great potential applications in antibacterial fabrics. In this study, an N-halamine monomer precursor was synthesized and treated onto PET fabrics. The treated PET fabrics were rendered antibacterial functionality after chlorination, and exhibited good antibacterial properties with inactivation rate of 100.0 % for both E. coli O157:H7 and S. aureus. After 50 wash cycles, the chlorinated treated PET fabrics could maintain 80.0 % antibacterial efficacy, demonstrating durable antibacterial properties. Storage stability and UV irradiation tests showed that the treated PET fabrics had remarkable regenerable properties. The reduction of the breaking strength was within 12 % after treatment, which is in a satisfying range in antimicrobial finishing.

“…The abovementioned polymer matrix is widely known for its resistance to aqueous and polar organic media, as well as good biocompatibility, easy processing and forming. Moreover, the study performed by Wang et al [59] indicate that MA containing materials have no significant toxic effect regarding the growth of both Staphylococcus aureus and Escherichia coli. Therefore, plant fiber-based polymer materials described in this research could possibly be applied in medical and healthcare applications, e.g., drug delivery, wearables, different medical devices, pharmaceutical blisters, and trays.…”

The following article is the presentation attempt of cellulose hybrid chemical modification approach as a useful tool in improving the mechanical properties of plant fiber-filled polymer materials. The treatment process is a prolonged method of the cellulose maleinization and consists of two steps: 1. solvent exchange (altering fiber structure); 2. maleic anhydride (MA) chemical grafting (surface modification). Thanks to the incorporated treatment method, the created ethylene–norbornene copolymer composite specimen exhibited an improved performance, tensile strength at the level of (38.8 ± 0.8) MPa and (510 ± 20)% elongation at break, which is higher than for neat polymer matrix and could not be achieved in the case of regular MA treatment. Moreover, both the Payne effect and filler efficiency factor indicate a possibility of the fiber reinforcing nature that is not a common result. Additionally, the polymer matrix employed in this research is widely known for its excellent resistance to aqueous and polar organic media, good biocompatibility, and the ability to reproduce fine structures which makes it an interesting material regarding healthcare applications. Therefore, plant fiber-based polymer materials described in this research might be potentially applied in this area, e.g., medical devices, drug delivery, wearables, pharmaceutical blisters, and trays.

“…Many biocidal functionalities such as N -halamines ( N -chloramines and N -bromamines) [ 5 , 6 , 7 ], antibiotics [ 8 , 9 ], quaternary ammonia salts [ 10 , 11 , 12 ], reactive oxygen species [ 13 , 14 ], and heavy-metal ions [ 15 , 16 , 17 , 18 ] have been incorporated onto cellulose to give an antibacterial ability. N -halamines, produced by halogenation of imide/amide/amine N−H to N−X (X=Cl, Br), have many advantages, since they are highly powerful, rechargeable, broad-spectrum, and not susceptible to bacterial resistance.…”

Cyclic N-halamines are highly antimicrobial, very stable, and not susceptible to bacterial resistance. A polysiloxane delivery vehicle was synthesized to deliver cyclic imide N-halamine onto cellulose via a benign and universal procedure that does not require a harmful solvent or chemical bonding. In brief, Knoevenagel condensation between barbituric acid and 4-hydroxybenzaldehyde furnished 5-(4-hydroxybenzylidene)pyrimidine-2,4,6-trione, whose phenolic O−H was subsequently reacted with the Si−H of poly(methylhydrosiloxane) (PMHS) via silane alcoholysis. The product of silane alcoholysis was interpenetrated into cellulose in supercritical CO2 (scCO2) at 50 °C, to form a continuous modification layer. The thickness of the modification layer positively correlated with interpenetration pressure in the experimental range of 10 to 28 MPa and reached a maximum value of 76.5 nm, which demonstrates the ability for tunable delivery, to control the loading of the imide N−H bond originating from barbituric acid unit. The imide N−H bonds on cellulose with the thickest modifier were then chlorinated into N−Cl counterparts using tert-butyl hypochlorite, to exert a powerful biocidability, providing ~7 log reductions of both S. aureus and E. coli in 20 min. The stability and rechargeability of the biocidability were both very promising, suggesting that the polysiloxane modifier has a satisfactory chemical structure and interlocks firmly with cellulose via scCO2 interpenetration.
