“…Investigations carried out by Shankar and Rhim , where they prepared films composed of PBAT and silver nanoparticles (PBAT/Ag‐NPs), showed strong antibacterial activity against E. coli and L. monocytogenes compared to PBAT films without Ag‐NPs load. Likewise, comparable results were obtained by Venkatesan and Rajeswari when they incorporated ZnO nanoparticles into a PBAT matrix and evaluated antibacterial activity. In this research, it was observed that the PBAT compound, which was used as the control matrix, showed no antibacterial activity compared to the PBAT/ZnO nanocomposite films.…”

“…In the thermograms, it is observed that the presence of Cu‐NPs slightly increases the thermal stability of the nanocomposites compared to the unfilled polymer. This enhancement in thermal stability was attributed to the barrier effect of Cu‐NPs . The degradation percentages around 420°C–427°C of the PBAT matrix and NCs‐PBAT/Cu (1, 3, and 5% (w/w)) were 98.9%, 97.5%, 95.4%, and 96.8%, respectively.…”

“…In both cases, the improvement with nanoparticle is not significant in comparison to the use of nanowires . By using FTIR, it was determined that there is no effective interaction between the Cu‐NPs surface and PBAT matrix since the slight improvement found in the mechanical properties of the nanocomposites is due to processes of loads entanglement with the polymer chains of the matrix .…”

Poly(butylene adipate‐co‐terephthalate) (PBAT) was mixed with copper nanoparticles (Cu‐NPs) in concentrations of 1%, 3%, and 5% with particle size between 100 nm and 200 nm by the melting method. A morphological, thermal, and structural characterization of the nanocomposites (NCs‐PBAT/Cu) was performed to analyze the effect of the Cu‐NPs on the polymer chains, as well as to explain the influence on their crystallinity, and its influence on the thermomechanical and antibacterial properties. The percentage of crystallinity (Xc) increased 6.7% to 9.5% with the amount of Cu‐NPs in the matrix. E‐modulus was slightly improved from 84.04 to 87.7 MPa, in the same way the degradation temperature (Td) of the PBTA was improved from 420.7°C to 427.2°C for 5% loading of Cu‐NPs. In contrast, ΔHm decreased from 12.50 to 6.96 J/g, indicating that there was no significant modification of the PBAT chain, mainly by heterogeneous nucleation in the presence of Cu‐NPs, which act as a heat barrier. No blue or red shifts we observed in the nanocomposites Fourier transform infrared (FTIR) spectra, indicating there is no effective interaction between PBAT and Cu‐NPs. The nanocomposites showed excellent antibacterial properties inhibiting 100% of the strains Enterococcus faecalis, Streptococcus mutans, and Staphylococcus aureus, at 2 hours of treatment. For more resistant strains such as Acinetobacter baumannii, the NCs‐PBAT/Cu did not show antibacterial activity at any time of treatment. POLYM.

“…3 and 4, the tensile strength monotonically decreased, but the elongation at break and the Young's modulus were at the same level. Due to the incompatibility between PBAT and TPS/ATPS, TPS/ATPS dispersed as particles in PBAT matrix, as shown in other studies [36,37] and our previous work [38]. The SEM images in Fig.…”

“…Although there are several reports on the use of TPS with lignocellulosic fibers, few of those are about the biodegradation of PBAT/TPS blends, and none of them deal with the biodegradation of PBAT/TPS/lignocellulosic fiber systems. The majority of the studies involving these blends evaluates the addition of a third polymer to the blend, the use of compatibilizers, the addition of layered silicates, and the influence of processing on the degradation of these materials …”

The influence of thermoplastic starch (TPS) and babassu mesocarp incorporation on the biodegradation of poly(butylene adipate‐co‐terephthalate), PBAT, PBAT/TPS blend, and its biocomposite were investigated. PBAT/TPS blend (70:30) and its biocomposite containing 20% babassu (i.e., 17:58:25% wt/wt babassu mesocarp/PBAT/TPS system) were prepared by melt blending in a torque rheometer at 150 °C. Samples for biodegradation were obtained by hot pressing. Size exclusion chromatography showed that incorporation of TPS and babassu mesocarp to PBAT led to a reduction in PBAT molecular weight on the blends and composite. The reduction was higher on the blends than in the composite. Respirometry data showed that while addition of TPS accelerated biodegradation incorporation of babassu retarded it.
