Antibacterial performance of the PVDF membranes doped with Ag photodeposited TiO2 particles

PVDF/Fe3O4@pDA@Ag Nanofiber Membranes with Multicore–Shell Structure for EMI Shielding

“…There were asymmetric stretching vibration bands at 836 and 1273 cm – 1 , and a bending vibration band associated with −CF 2 was identified at 475 cm – 1 . These peaks were identical to the chemical structure of PVDF. − In the spectra of PVDF/Fe 3 O 4 and PVDF/Fe 3 O 4 @pDA NFMs, the characteristic peak at 562 cm – 1 was assigned to Fe–O stretching in Fe 3 O 4 NPs. , Moreover, in the PVDF/Fe 3 O 4 @pDA spectrum, −NH bending vibration was detected near 1597 cm – 1 due to a large amount of −NH in pDA. , In the PVDF/Fe 3 O 4 @pDA@Ag spectrum, due to the complete coverage of the fiber surface by the Ag layer, only the Ag–O characteristic peak at 533 cm – 1 was detected …”

Preparation and antibacterial properties of polypropylene composite with bisphenol A-type benzoxazine.

“…This type of antimicrobial agent has advantages such as non-toxicity and strong biocompatibility, but their poor stability, low temperature resistance, and complex processing methods greatly limit their use [14,15]. Inorganic antimicrobial agents usually refer to metal ions or oxides with antimicrobial activity, including Ag + [16][17][18], TiO2 [19], ZnO [20] and so on. Inorganic antimicrobial agents have certain advantages in terms of heat resistance, safety, antimicrobial activity, and durability, but they also have some disadvantages such as high cost and poor compatibility.…”
