“…Additionally, the infrared absorption peak at 1352 cm −1 for NiAl-LDHs and LDHs@TA-Ti was attributed to the vibrations of CO 3 2 ⁻ in the interlayer [ 19 ]. Compared with NiAl-LDHs, LDHs@TA-Ti shows additional peaks at 1709, 1496, 1320 and 1197 cm −1 , which corresponded to C=O (ester groups), C–O, aromatic C=C and phenolic hydroxyl in TA, respectively [ 20 , 21 , 22 ]. In addition, the bands recorded below 700 cm −1 were attributed to metal-oxygen vibration in NiAl-LDHs [ 15 ].…”

Inspired by complexation and mussel adhesion of catechol groups in tannic acid (TA), organophilic layered double hydroxides (LDHs@TA-Ti) were synthesized by forming a one-pot assembled TA-titanium (Ti) dual network coating on the surface of layered clay for the first time. LDHs@TA-Ti/poly(vinyl alcohol) (PVA) nanocomposites were prepared by the solution casting method. The results show that TA-Ti(IV) and TiO2 coordination compounds are simultaneously formed due to hydrolysis of titanium tetrachloride and complexation of TA in aqueous solution. Upon TA-Ti coatings onto the surface of LDHs, the antibacterial rate of LDHs@TA-Ti is up to 99.98%. Corresponding LDHs@TA-Ti/PVA nanocomposites also show outstanding antibacterial properties. Compared with pure PVA, LDHs@TA-Ti/PVA nanocomposites show a 40.9% increase in tensile strength, a 17.5% increase in elongation at break, a 35.9% decrease in oxygen permeability and a 26.0% decrease in water vapor permeability when adding 1 wt % LDHs@TA-Ti. UV transmittance (at 300 nm) of LDHs@TA-Ti/PVA nanocomposites decrease by 99.4% when the content of LDHs@TA-Ti reaches 3 wt %. These results indicate that PVA matrix incorporated with LDHs@TA-Ti could be used as a potential active packaging material to extend the shelf life of food products.

“…The FT‐IR spectra of CMC showed that peak at 1585 cm −1 due to the stretching vibrations of carbonyl (CO), peak at 1410 cm −1 due to the characteristic peak of COO on CMC, and the peak at 1317 cm −1 was corresponding to CO stretching . Furthermore, peaks originating from ring stretching in benzene from 1500 to 1600 cm −1 were observed owing to the benzene moieties of TA . However, in the hydrogel formed from CMC and TA, a decrease in the peaks for ring stretching in benzene and a decrease in OH and/or NH stretch vibration peaks were detected obviously.…”

Hemostatic microparticles (HMs) have been widely used in surgery. To improve the comprehensive performance of HMs, multifunctional HMs named HM15 and HM15′ are prepared from starch, carboxymethyl chitosan, hyaluronic acid, and tannic acid. Herein, tannic acid is used as an effective cross‐linker. A 3D network structure for cell growth and wound repair can be formed by secondary cross‐linking. Through synergistic effect of these natural materials, the process of wound healing can be regulated controllably. HM15 and HM15′ have the ability of rapid hemostasis. Moreover, HM15′ shows excellent properties in antibacteria and wound healing acceleration. Blood clotting time treated with different HMs is shortened obviously from 436.8 s to 126 s. Compared with Celox, HM15 and HM15′ exhibited better broad spectrum antibacterial activity against both Escherichia coli and Staphylococcus aureus. Notably, the wound can be repaired rapidly by HM15′ in 14 days. These multifunctional HMs might have an important prospect in clinical application.

“…Interestingly, the antifouling performance of PMPDSAH coated surfaces is outperforming that of the PEG surfaces [ 137 ]. Moreover, this polymer can be functionalized by a 1.9 nm thick metal–polyphenol coating to make it attractive to proteins and cells [ 138 ]. This is particularly important when targeting the spatio-selective functionalization of a specific surface.…”

Pathogenic microbes are the main cause of various undesired infections in living organisms, including humans. Most of these infections are favored in hospital environments where humans are being treated with antibiotics and where some microbes succeed in developing resistance to such drugs. As a consequence, our society is currently researching for alternative, yet more efficient antimicrobial solutions. Certain natural and synthetic polymers are versatile materials that have already proved themselves to be highly suitable for the development of the next-generation of antimicrobial systems that can efficiently prevent and kill microbes in various environments. Here, we discuss the latest developments of polymeric structures, exhibiting (reinforced) antimicrobial attributes that can be assembled on surfaces and coatings either from synthetic polymers displaying antiadhesive and/or antimicrobial properties or from blends and nanocomposites based on such polymers.
