Multifunctional cinnamaldehyde-tannic acid nano-emulsion/chitosan composite film for mushroom preservation

Construction of highly hydrated and mechanically strong anti-fouling coatings for deep-sea probes based on poly(vinyl alcohol) tannic acid zwitterion coatings

“…Second, it was also found that TA enhances the film-forming ability of PVA, resulting in a denser surface film. 33 This is further evidenced by the EDX spectral distribution, which shows a uniform distribution of the components C, N, O and S throughout the hydrogel coating polymer. The hydrophilicity of the composite is attributed to these components.…”

“…Furthermore, optical microscopy images showed the presence of a multidimensional pore structure in the PVATAZ hydrogel coating, which would allow the material to have superior biocompatibility 34 and adsorption capacity. 33 In conclusion, PVATAZ hydrogel coatings exhibit very good surface quality and are ideal for marine antifouling applications. These observations highlight the potential of the hydrogel coatings for use in a variety of anti-fouling device surface applications and implants, providing in-depth information on the structure and properties of the hydrogel coatings.…”

Thermal-Driven Curcumin Release Film with Dual-Mode Synergistic Antibacterial Behavior for Efficient Tangerine Preservation

“…After being placed under 25 °C for 24 h (RH: 50%), the final weight of the cups was measured. The following eq was used to calculate the value of WVP: WVP = normalΔ m × d S × t × normalΔ P where Δ m is the weight change (g) of the cups, d represents the thickness of the film (m), S indicates the area of the film used to cover the cup (m 2 ), t is the duration of the test process (s), and Δ P is the partial vapor pressure (1584 Pa).…”

“…0.5 g of reduced iron powder, 1.5 g sodium chloride and 1 g of activated carbon were added to the test vessel, and the test vessel was covered with a film sample. The weight of the test vessel initially and after being placed for 48 h under 25 °C was recorded OP = normalΔ m × d A × t Where Δ m is the weight change of test vessel (g).…”
