“…52 Besides, adding the CNFs/CNCs with higher strength and crystallinity to the viscoelastic PLA polymer matrix played a role in sharing the load. 53 As depicted in Fig. 2, the crystallinity of CNCs (83.5%) was significantly higher than that of CNFs (58.2%), such that the breaking strength of the PLA-CNCs film was significantly greater than that of PLA-CNFs film, and the results were consistent with the crystallinity results of the composite film.…”

“…For calculations of the heat involved in the processes and the melting and crystallization temperatures that occurred during heating and cooling, TA60WS software (Kyoto, Japan) was used. The calculation of polymer crystallinity was also performed using Equation (1), conceived by Rossin and Aldhafeeri [ 25 , 26 ]. X c = (Δ H m − Δ H c /Δ H ° m ) × 100 where X c is the degree of crystallinity of the polymer, Δ H cc is cold crystallization enthalpy of the sample, Δ H m is fusion enthalpy of the sample, Δ H° m is theoretical fusion enthalpy of the 100% crystalline sample; in the case of PBAT, Δ H° m = 114 J·g −1 , and, for PLA, Δ H° m = 93.7 J·g −1 .…”

This work aimed to use the electrospinning technique to obtain PBAT/PLA polymer fibers, with the semiconductors rutile titanium dioxide (TiO2-R) and magnetite iron oxide (Fe3O4), in order to promote the photocatalytic degradation of environmental contaminants. The parameters used in the electrospinning process to obtain the fibers were distance from the needle to the collecting target of 12 cm, flow of 1 mL h−1 and voltage of 14 kV. The best mass ratio of semiconductors in the polymeric fiber was defined from a 22 experimental design, and the values obtained were 10% TiO2-R, 1% Fe3O4 at pH 7.0. Polymer fibers were characterized by Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and Fourier Transform Infrared (FTIR) techniques. SEM measurements indicated a reduction in fiber diameter after the incorporation of semiconductors; for the PBAT/PLA fiber, the average diameter was 0.9466 ± 0.2490 µm, and for the fiber with TiO2-R and Fe3O4 was 0.6706 ± 0.1447 µm. In the DSC, DRX, TGA and FTIR analyses, it was possible to identify the presence of TiO2-R and Fe3O4 in the fibers, as well as their interactions with polymers, demonstrating changes in the crystallinity and degradation temperature of the material. These fibers were tested against Reactive Red 195 dye, showing an efficiency of 64.0% within 24 h, showing promise for photocatalytic degradation of environmental contaminants.

In this work, polylactic acid/poly (butylene adipate-co-terephthalate) (PLA/PBAT) melt-blown nonwovens with well oil-water separation properties were made with melt-blown technology. The thermal, crystalline, morphology, mechanical properties, wettability, and oil-water separation performance of the PLA/PBAT melt-blown nonwovens were thoroughly investigated. The result of DSC and WAXD show that PBAT promotes the movement of the PLA molecular chain and promotes crystallinity. With increasing the blending ratio of PBAT, the ΔH m and degree of crystallinity (X c ) of PLA were also enhanced from 38.1 to 55.1 J/g and from 1.5-15.5%, respectively, which were higher than neat PLA. Furthermore, PBAT increases the toughness and hydrophobic of the PLA melt-blown nonwovens. The elongation at break of PLA/PBAT 90/10 (53.3 ± 3.7%) was 12.3% higher than the neat PLA melt-blown nonwovens (41.0 ± 2.9%).The result of the research on the in uence of the oil-water separation parameters and oil absorption experiments shows that the 90/10 PLA/PBAT melt-blown nonwoven exhibits the highest hydrophobic (water contact angle is 133.2 o ). Meanwhile, the maximum adsorption e ciency of cyclohexane of nonwovens reaches 5.18 g/g. The PLA/PBAT melt-blown nonwovens have excellent oil-water separation capability.
