“…Thus, GO‐Ag hybrid nanofillers induced better improvement on the mechanical performance of CG nanofibers than simple mixture of GO and AgNPs fillers. In fact, similar synergistical effect of hybrid fillers on mechanical properties of polymer was also witnessed on GO‐ZnO/poly(lactic acid) and GO‐Ag/PVA composites . Thus, GO‐Ag is excellent candidate for improving the mechanical properties of PEC nanofibers for more demanding biomedical applications.…”

The poor mechanical and antibacterial performance has become a big hurdle for extending the application of polyelectrolyte complex (PEC) nanofibers in various fields. In this study, chitosan/gelatin (CG) composite nanofiber system was used for portraying the synergistic enhancement of mechanical and antibacterial properties of PEC nanofiber membranes by inclusion of graphene oxide‐silver (GO‐Ag) nanofillers. In particular, the introduction of 1.5 wt % GO‐Ag has raised the elastic modulus and tensile strength of CG nanofiber membrane by 105% and 488%, respectively, which are partially attributed to the alleviated restacking of graphene sheets by the anchored AgNPs. Meanwhile, the diameters of inhibition zone against Escherichia coli and Staphylococcus aureus on LB‐agar plates induced by GO‐Ag/CG nanofiber membranes are increased by 80.5% and 50.1%, respectively, compared to that by CG membrane. The synergistic improvement of antimicrobial performance of GO‐Ag/CG may be related to the accumulation of microorganisms induced by GO. In summary, the incorporation of GO‐Ag composite nanofillers has emerged as an effective strategy for engineering PEC nanofiber membranes for potential applications in nanomedicine and tissue engineering. © 2018 Wiley Periodicals, Inc.

Recently, silicone rubber (VMQ) was extensively used in household articles and medical devices. To develop a kind of safe and long‐term antimicrobial VMQ was of great significance. In this work, a kind of vinyl‐contained polyhexamethylene guanidine hydrochloride (VPHMG) was synthesized and used as antimicrobial additive for VMQ. With the increasing of VPHMG addition, the mechanical properties and antimicrobial properties of VMQ‐VPHMG were significantly improved. In particular, the antimicrobial rates against Escherichia coli and Staphylococcus aureus were higher than 99.99% as for 4 wt% of VPHMG addition. Moreover, the surface concentration of VPHMG as well as the antimicrobial rates revealed almost unchanged after being extracted by water and methanol. All the results indicated the vinyl‐contained VPHMG vulcanization and therefore provided the permanent antimicrobial performance for VMQ.

The starch/PVA films with the addition of 30 wt.% Ca(NO3)2 and different content of Tween 20 are prepared by solution casting. The effect of Ca(NO3)2 on the crystalline, thermal, and mechanical properties of starch/PVA film is studied by X‐ray diffraction measurement, differential scanning calorimetry and tensile testing, respectively. The effect of Tween 20 on the properties of Ca(NO3)2 doped starch/PVA film is studied. The water sorption properties and the water vapor barrier properties of starch/PVA films are studied. The results shows that Ca(NO3)2 can effectively destroy the crystals of starch and PVA. The Ca(NO3)2 doped starch/PVA film shows a high water sorption rate and low water vapor barrier properties. Tween 20 can increase the water resisting properties and increase the flexibility of Ca(NO3)2 doped starch/PVA film. With the combination of Ca(NO3)2 and Tween 20 the flexible starch/PVA film with a high water resisting ability is obtained.
