Incorporation of hydrophilic ZnO-lignin into the polyamide layer induces the formation of nanochannels around the nanoparticles since water molecules absorbed on hydrophilic nanoparticles can terminate the interfacial polymerization by hydrolysis of trimesoyl chloride monomers. In addition, ZnO-lignin significantly impacts the polyamide layer’s properties in the modified TFN membranes, which had measurably more hydrophilic, thinner and smoother surfaces than the bare thin film composite (TFC) membrane. The covalent bonding of hydroxyl groups with trimesoyl chloride enables the synthesis of a thin polyamide film with high stability and improved performance. At the same time, the sulfonic groups endive membrane surfaces with a negative charge, hence immensely enhancing the membrane selectivity toward NaCl and heavy metal ions. These changes in the properties of the polyamide layer are nearly twice the water flux and raise the selectivity for the optimal membrane. With the assistance of 400 ppm of ZnO-lignin, the water flux of the TFN-ZLS.2 membranes were augmented up to 22.5 LMH, corresponding to 95% of the water flux enhancement compared to the control TFC membrane. In addition, the TFN-ZLS.2 membrane presented higher rejection toward Cr<sup>+3</sup> and Cu<sup>+2</sup> than control TFC membranes, verifying enhancement of the selectivity of the polyamide layer by incorporating ZnO-lignin. Our results indicate that hydrophilic shells in ZnO-lignin nanoparticles significantly develop TFN membranes with high separation performance.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 2","pages":"899 - 909"},"PeriodicalIF":4.7,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While poly(lactic acid) (PLA) remains among the most widely used bio-based compostable polymers in material extrusion, its inherent brittleness imposes limitations in sectors requiring more flexible and ductile materials. In this context, the combination of PLA with poly(butylene adipate-co-terephthalate) (PBAT) results in more flexible compostable blends, broadening the scope of advanced applications of 3D-printed parts while upholding sustainability standards. Despite the considerable potential of PLA/PBAT blends, research on their use in material extrusion 3D printing remains limited, highlighting an opportunity for significant advancements in the near future. Therefore, this article provides a detailed review of the influence of printing parameters on the properties of 3D-printed PLA/PBAT blends. It begins with a brief overview of the synthesis methods of PLA and PBAT, and their blend compatibilization strategies, showcasing advancements in the pursuit of versatile and sustainable materials. Furthermore, it also examines potential applications while identifying research gaps that can steer future investigations. In essence, this review not only provides valuable insights for optimizing the printing parameters of these blends in extrusion-based 3D printing but also contributes to the development of more adaptable and sustainable materials, holding substantial promise across various technological domains.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 2","pages":"631 - 659"},"PeriodicalIF":4.7,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance the solubility of CSNPs further cross-linked with polyethylene glycol (PEG) (PEG/CSNPs@BTZ-VCR). Several methods were used to examine the NPs.

The synergic effect of the BTZ and VCR was considerably more potent, with 0.22 of PEG/CSNPs@BTZ-VCR NPs. In addition, PEG/CSNPs@BTZ-VCR NPs have a higher DPPH scavenging activity (58.32%) than drug-alone. The synergistic efficiency of the PEG/CSNPs@BTZ-VCR NPs triggers apoptosis variations was detected using Calcein AM/Propidium Iodide (PI), DAPI, and PI biochemical staining techniques.
