“…The extensive utilization of plastics has given rise to escalating environmental challenges due to their exceptionally slow degradation rate upon disposal as waste. 1,2 However, the environmental damage caused by cumulative nondegradable plastic waste is being overlooked owing to the convenience of its use. 3 Fiber-based products account for a significant proportion of plastic goods in the industry.…”

Fiber‐based products constitute a significant portion of plastic waste and cause environmental damage. In particular, discarded sanitary masks and fishing gear disintegrate into microfiber plastics, posing a significant threat to human health and ecosystems. In this study, we developed robust biodegradable nanocomposite fibers of poly(butylene adipate‐co‐terephthalate) (PBAT)/cellulose nanocrystals (CNCs) (1 and 2 wt%) through dry‐jet wet spinning, by using dimethyl sulfoxide (DMSO) as a common solvent. The control PBAT fibers exhibit remarkable mechanical performance with tensile strength and toughness of 160.0 MPa and 43.0 MJ m−3, respectively. CNC addition has a toughening effect with slightly reduced strength but enhanced toughness (148.8 MPa and 69.0 MJ m−3, respectively, for 2 wt% CNC); their mechanical performances are superior to those of previously reported PBAT‐based materials. The remarkable performance of the fibers is attributed to a highly oriented structure with a total draw ratio of 15 after post‐hot drawing. The control and nanocomposite fibers exhibit spot‐like patterns in 2D wide‐angle x‐ray diffraction patterns with Herman's orientation factor of 0.54–0.58. The theoretical Hansen solubility parameter confirmed the poor chemical affinity between the PBAT and CNC. Nonetheless, the rheological characterization revealed that well‐dispersed CNCs with DMSO produced a physical network in the PBAT matrix, resulting in the toughening effect. Such robust nanocomposite fibers consisting of fully biodegradable components are promising alternatives to nondegradable nylon and polyester fibers.Highlights Robust biodegradable nanocomposite fibers of PBAT and CNC are prepared. Nanocomposite fibers are dry‐jet wet spun using DMSO as a common solvent. PBAT fibers exhibit strength and toughness of 160.0 MPa and 43.0 MJ m−3. 2 wt% CNC toughens the PBAT fibers with an enhanced toughness of 69.0 MJ m−3. Rheological results confirm the toughening effect of well‐dispersed CNC in PBAT.

“…Plastics are regarded as indispensable commodities that significantly improve the quality of human life owing to their advantageous properties, including high flexibility, cost-effectiveness, convenient processing, and light weight [ 1 – 4 ]. Plastics are generally produced using more than one petroleum-based monomer, where this process is the main cause of the depletion of fossil fuels.…”

“…6 In this respect, the development of biodegradable polymeric materials represents a simple and viable solution to reduce the environmental footprint due to the increasing utilization of single-use plastics. 7 Among commercially available biodegradable polymers, poly(butylene succinate) (PBS) is considered an emerging material. PBS is an aliphatic thermoplastic polyester (Figure 1a) with good mechanical properties that are comparable to polyethylene (PE) and polypropylene (PP).…”

The introduction of inorganic materials into biopolymers has been envisioned as a viable option to modify the optical and structural properties of these polymers and promote their exploitation in different application fields. In this work, the growth of Al 2 O 3 in freestanding ∼30-μm-thick poly(butylene succinate) (PBS) films by sequential infiltration (SIS) at 70 °C via trimethylaluminum (TMA) and H 2 O precursors was investigated for the first time. The incorporation of Al 2 O 3 into the PBS matrix was clearly demonstrated by XPS analysis and SEM-EDX cross-sectional images showing a homogeneous Al 2 O 3 distribution inside the PBS films. Raman measurements on infiltrated freestanding PBS show a reduction of the signal related to the ester carbonyl group as compared to pristine freestanding PBS films. Accordingly, FTIR and NMR characterization highlighted that the ester group is involved in polymer–precursor interaction, leading to the formation of an aliphatic group and the concomitant rupture of the main polymeric chain. Al 2 O 3 mass uptake as a function of the number of SIS cycles was studied by infiltration in thin PBS films spin-coated on Si substrates ranging from 30 to 70 nm. Mass uptake in the PBS films was found to be much higher than in standard poly(methyl methacrylate) (PMMA) films, under the same process conditions. Considering that the density of reactive sites in the two polymers is roughly the same, the observed difference in Al 2 O 3 mass uptake is explained based on the different free volume of these polymers and the specific reaction mechanism proposed for PBS. These results assessed the possibility to use SIS as a tool for the growth of metal oxides into biopolymers, paving the way to the synthesis of organic–inorganic hybrid materials with tailored characteristics.
