“…It is well known that metal oxides can induce thermal degradation of PLA by unzipping depolymerization [31] . A similar effect on thermal degradation was reported for cerium oxide incorporation in PLA [32] . The negative-charged oxygen from PLA chain interacts with positive-charged cerium atoms from CeNPs, while the oxygen from CeNPs interacts with the carbon from the PLA carboxyl group, leading to a catalytic depolymerization.…”

“…It has good biocompatibility and biodegradability and is widely used in the fields of packaging, biomedical materials, and agriculture. [1][2][3][4][5] However, its poor crystallization and mechanical properties limit its application. [6,7] Compounding PLA with inorganic fibers is an effective way to enhance the crystallization ability and mechanical properties of PLA.…”

Carbon fiber fabric reinforced poly(lactic acid) (CFF/PLA) composites were manufactured using both vacuum‐assisted resin transfer molding (VARTM) and compression molding (CM) methods. Of the two methods, the CFF/PLA‐VARTM composite shows superior carbon fiber infiltration and interfacial adhesion compared to the CFF/PLA‐CM composite. The improved infiltration enables the carbon fibers to induce a dense group of PLA crystal nuclei along their surface, resulting in the formation of a trans‐crystalline layer (TCL) structure where the PLA lamellae grow perpendicular to the fiber axis. As a result, the interfacial adhesion is improved, and the crystallinity of the PLA in the CFF/PLA‐VARTM composite is 4.1 times higher than that of pure PLA. However, the weak infiltration of fibers and matrix in CFF/PLA‐CM composite results in poor load‐bearing ability. Conversely, CFF/PLA‐VARTM composite presents better interlayer bonding and tight fiber‐matrix wrapping, promoting effective tensile load transfer to carbon fibers, which results in higher strength and modulus. The presence of TCL structures also plays a key role in improving mechanical properties. Overall, these findings demonstrate a promising method for producing high‐performance PLA composites.

“…Compared with petroleum-based polymers, polylactic acid (PLA) has received much attention as a biodegradable hydrophobic polymer [7][8][9]. PLA synthetic raw materials are widely available and inexpensive and have been used in the packaging [10], medical [11], and textile fields [12]. Therefore, they have become one of the best alternative materials to improve disposable masks [13,14].…”

With the increasing environmental pollution caused by disposable masks, it is crucial to develop new degradable filtration materials for medical masks. ZnO-PLLA/PLLA (L-lactide) copolymers prepared from nano ZnO and L-lactide were used to prepare fiber films for air filtration by electrospinning technology. Structural characterization of ZnO-PLLA by H-NMR, XPS, and XRD demonstrated that ZnO was successfully grafted onto PLLA. An L9(43) standard orthogonal array was employed to evaluate the effects of the ZnO-PLLA concentration, ZnO-PLLA/PLLA content, DCM(dichloromethane) to DMF(N,N-dimethylformamide) ratio, and spinning time on the air filtration capacity of ZnO-PLLA/PLLA nanofiber films. It is noteworthy that the introduction of ZnO is important for the enhancement of the quality factor (QF). The optimal group obtained was sample No. 7, where the QF was 0.1403 Pa−1, the particle filtration efficiency (PFE) was 98.3%, the bacteria filtration efficiency (BFE) was 98.42%, and the airflow resistance (Δp) was 29.2 Pa. Therefore, the as-prepared ZnO-PLLA/PLLA film has potential for the development of degradable masks.
