The morphology of the particle-coated scaffolds was examined; it was observed that the particles obtained were monodisperse and of an ideal size for the intended application. According to the drug-release results, the release of drugs was completed in 24 h from the CS/PLA-2RIF scaffold and in 48 h from the CS/PLA-3RIF scaffold. Antimicrobial analysis was performed using <i>Escherichia coli</i> and <i>Staphylococcus aureus</i>; the scaffolds showed effectiveness against these bacterial strains. Per MTT analysis, the scaffolds had no toxic effects; it was noted that the cells easily adapted to the scaffold.

The drug-release results indicate that the release of the drugs was completed in 24 h from the CS/PLA-2RIF scaffold and in 48 h from the CS/PLA-3RIF scaffold. Antimicrobial analysis was conducted using <i>Escherichia coli</i> and <i>Staphylococcus aureus</i>; the scaffolds showed effectiveness against these bacterial strains. Larger zones were demonstrated in testing the scaffolds with gram-positive bacteria; smaller zones were demonstrated in testing the scaffolds with gram-negative bacteria. The PLS/CS scaffold was associated with a small inhibition zone; this finding was attributed to the natural antimicrobial effect of CS. The MTT results suggest that scaffolds were not associated with toxic effects. The results of this study suggest that the wound dressing obtained by combining 3D printing and EHDA methods could provide an alternative approach to treat HS.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"9 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141869406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Multifiller carbon nanotube, graphene, and carbon black composite filaments: A path to versatile electromaterials","authors":"Sandra Lepak-Kuc, Łukasz Nowicki, Agnieszka Lekawa-Raus, Malgorzata Jakubowska","doi":"10.1557/s43577-024-00757-y","DOIUrl":"https://doi.org/10.1557/s43577-024-00757-y","url":null,"abstract":"<h3 data-test=\"abstract-sub-heading\">Abstract</h3><p>Addressing the growing demand for conductive and flexible composites, this research focuses on producing thermoplastic composite fibers made of polyurethane and carbon nanomaterials featuring the highest possible electrical conductivity. Based on a recently developed methodology enabling the formation of very high filler contents of 40% w/w, this work presents a systematic investigation of the role of all the materials used during the manufacturing process and selects the materials that ensure the best electrical performance. The results show that the highest electrical conductivity and current-carrying capacities are obtained when dimethylformamide is used as a solvent, and small amounts of AKM surfactant aid the de-agglomeration of carbon nanomaterials. It is also shown that the hybridization of MWCNTs filler with graphene nanoplatelets and small amounts of carbon black is beneficial for the electrical properties. However, the highest performance is achieved with SWCNTs as fillers, exhibiting two orders of magnitude higher electrical conductivities of 6.17 × 10⁴ S/m.</p><h3 data-test=\"abstract-sub-heading\">Impact statement</h3><p>The article presents a pioneering exploration into the synthesis and application of a novel composite material. This research significantly impacts the field of electromaterials by introducing a cutting-edge approach that leverages the synergistic properties of carbon nanotubes, graphene, and carbon black within a single filament. The impact of this research extends beyond the laboratory, influencing the development of next-generation materials that bridge the gap between conventional materials and advanced nanomaterials. The presented composite filaments open avenues for the creation of innovative devices and systems that demand good mechanical strength, electrical conductivity, and thermal stability. Moreover, the versatility of these filaments allows for the optimization of materials properties, enabling customization based on specific application requirements. In addition to its technological significance, the paper contributes to sustainability efforts by facilitating the production of lightweight, energy-efficient materials. The insights provided by this research have the potential to reshape the landscape of materials science, inspiring further exploration and innovation in the quest for versatile and high-performance electromaterials.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"19 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141869405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
