“…Curcumin was consistently spread in all the polymers to form transparent yellowish flexible films, except for the translucent PBAT film [ 8 , 9 , 10 ]. The release patterns of curcumin from the natural biopolymer-based and bioplastic-based functional films are shown in Figure 1 and Figure 2 , respectively.…”

“…Such a difference in the curcumin release rate is mainly due to the difference in the polymeric films’ water solubility and swelling ratio, leading to the different diffusion rates of curcumin [ 8 ]. However, there was no noteworthy variance in the release profile of curcumin in the bioplastic-based films ( Figure 2 ), mainly attributed to the hydrophobicity of both the PLA- and PBAT-based films with low water solubility and a low swelling ratio [ 9 , 10 ]. In general, various factors such as the solubility and swelling ratio of the polymer matrix, the solubility and compatibility of the bioactive compounds, and the integrity of the composite polymer are known to play a vital role in releasing the active compounds [ 9 , 34 , 35 ].…”

“…The PLA/curcumin and PBAT/curcumin films were also fabricated using the solution casting method [ 9 , 10 ]. First, 0.04 g of curcumin was added to 100 mL of chloroform and dispersed for 2 h with gentle agitation, and then 4 g of each bioplastic (PLA or PBAT) was gradually integrated into the curcumin solution and dissolved (48 h with gentle stirring).…”

“…Recently, curcumin has been used to manufacture bioactive packaging, and in biomedical applications. Some of the results showed it could be a promising candidate for manufacturing bioactive packaging films [5][6][7][8][9][10][11]. The functional material curcumin is released from the film upon contact with food to provide functionality through dissolution, diffusion, partitioning, swelling, and targeting.…”

This work reports the effects of free volume on curcumin release in various polymer-based composite films. Curcumin-reinforced biocomposite films were fabricated with natural biopolymers (carrageenan and chitosan) and bioplastics (poly(lactide) (PLA) and poly (butylene adipate-co-terephthalate) (PBAT)) via the solvent casting method. The curcumin release test was performed using an aqueous medium, and it was found that it was released the fastest in the carrageenan film, followed by the chitosan, PLA, and PBAT films, presumably owing to the dissimilarity of the polymer matrix. The free volume of the polymer films was determined using positron annihilation lifetime spectroscopy (PALS) to understand the release phenomena of curcumin. The free volume fraction was varied and reliant on the type of polymer, with the highest in the PBAT-based film followed by the PLA-, chitosan-, and carrageenan-based films. The free volume method helps analyze the release of bioactive compounds in a polymer matrix and may help to achieve a better understanding of the release of bioactive compounds.

Antibacterial films based on polylactic acid (PLA) were developed by blended with neem oil (NO) and curcumin via solvent casting technique. Nuclear magnetic resonance (NMR) results revealed the presence of fillers (NO and curcumin) in the PLA matrix. Without losing much of the PLA film's transparency, the composite film has exceptional ultra violet-blocking properties. The addition of NO to the PLA matrix increased the elongation of the composite film by reducing tensile strength while not affect their thermal stability. The water vapor transfer rate (WVTR), water contact angle (WCA), and oxygen transmission rate (OTR) of the film were marginally improved by the introduction of NO and curcumin. The curcumin inclusion prevented the plasticized PLA/NO/curcumin compositions surfaces from porosity according to the morphology studies. Further, the PLA/NO/curcumin composites films exhibited good antibacterial, antioxidant activity and therefore have the possibility to use as an active packaging material for food preservation and safety.

Poly(butylene adipate‐co‐terephthalate) (PBAT) is one of the solutions to the energy crisis and white pollution. However, the poor thermo‐oxidative stability limits its wide applications. In this work, Chrysanthemum morifolium extract (CME) as a natural additive was used to modify the PBAT. The oxidation onset temperature (OOT) results showed that the CME could provide PBAT with high thermal oxidation stability. By the presence of 2.5 wt% CME, the OOT value of PBAT‐CME2.5 increased by 52°C compared with the neat PBAT. The outstanding antioxidant capacity is attributed to the excellent free radical quenching capacity of CME, whose main components consist of six kinds of phenolic compounds. Moreover, the PBAT‐CME1.5 composite could achieve the balance between the mechanical property and thermo‐oxidative stability, the OOT result of PBAT‐CME1.5 increased by 42°C, the tensile strength reached 103.1%, and the elongation at break could retain 91.4% of that of neat PBAT. Besides, the processing property, degradation performance, and surface hydrophobic nature of modified PBAT samples were all improved. This work proposes a facile method to obtain completely natural biodegradable composites to expand the practical applications of PBAT.Highlights The main components in CME are phenolic compounds. CME showed high free radical scavenging efficiency. CME improved the thermal oxidation stability of the PBAT matrix. The addition of CME could still maintain good mechanical properties of PBAT. The introduction of CME promoted the degradation of PBAT films.
